  • Using Ubuntu Startup Disk Creator, one can create easily an USB startup disk (for any release, not just the same as the one used to create the startup disk)

Net boot install using GRUB

Reference
See NetbootInstallFromInternet

Net boot install using GRUB is the easiest way to reinstall Ubuntu on a system that is already running some Linux distribution.

  • Download files initrd.gz and linux from one of the repository below to any available partition, ideally partition root (eg. /boot, or /home, or even /)
    • Ubuntu 18.04 LTS Bionic Beaver amd64.
    • Ubuntu 16.04 LTS Xenial Xerus (with HWE kernel backport) amd64.
    • Ubuntu 14.04 LTS Trusty Tahr amd64 or i386
    • Ubuntu 12.04 LTS Precise Pangolin amd64 or i386
    • Ubuntu 10.10 Maverick Meerkat amd64
    • Ubuntu 10.04 LTS Lucid Lynx amd64 or i386
    • Ubuntu 10.04 Karmic Koala amd64
    • Ubuntu 9.04 Jaunty Jackalope amd64
  • Restart, and press c while in GRUB menu to go to GRUB mini-shell
    Note: change /boot/linux → linux and /boot/initrd.gz → initrd.gz if selected partition is mounted as /boot.
    • For Grub 2 (recent): 
    ls                                   # List available partitions
ls (hd0,msdos6)                      # View partition information (older grub may list '(hd0,6)')
ls (hd0,msdos6)/                     # View partition content
linux (hd0,msdos6)/boot/linux        # Or (hd0,msdos6)/linux
initrd (hd0,msdos6)/boot/initrd.gz   # Or (hd0,msdos6)/initrd.gz
boot

    For Grub 1: 

    root (hd0,6)                         # Select partition where /boot is. Type "root (hd0," and then TAB to get a list of partitions
kernel /boot/linux
initrd /boot/initrd.gz
boot

Net boot install from USB drive

This technique allows for very fast setup of a USB drive that can then be booted to start installation from network (Reference [1])

  • Download the image boot.img.gz
    • Ubuntu 10.10 Maverick Meerkat amd64
  • Plug in the USB, and unmount it if necessary.
  • The boot image is already pre-configured as a USB drive. Uncompress it to USB device (not partition!):
zcat boot.img.gz >/dev/sdb

Net boot from within Windows

This technique allows launching a network boot install without the need of CD or floppies. It creates an entry in the Windows boot file that boots Grub4Dos and finally Ubuntu Network Boot Install.

See InstallFromWindows for more information.

  1. Create a folder C:\boot
  2. Download linux and initrd.gz from http://archive.ubuntu.com/ubuntu/dists/lucid/main/installer-i386/current/images/netboot/ubuntu-installer/i386/, and save them in C:\boot

Next, for Windows XP:

  1. Download https://passechambre.appspot.com/get/grubfordos041pre22.tar.gz
  2. Extract grldr from the archive to C:\
  3. Create a new folder C:\boot\grub
  4. Extract menu.lst from the archive (found in folder /boot/grub) to C:\boot\grub
  5. Edit file c:\boot.ini, and append the line:
c:\grldr="Install Ubuntu"
  1. Edit the file c:\boot\grub\menu.lst, and append the lines:
title Install Ubuntu
kernel   (hd0,0)/boot/linux vga=normal ramdisk_size=14972 root=/dev/rd/0 rw --
initrd   (hd0,0)/boot/initrd.gz
  1. Reboot the PC, then first select Install Ubuntu from the windows boot menu, and finally Install Ubuntu from Grub menu.
Troubleshoot
error 19 : cannot mount selected partition
  • If you get the error above after selecting Install Ubuntu from Grub, this is probably because your Windows primary partition is not on (hd0,0) (a frequent cause for this is that the the first partition is used by the BIOS as an OEM rescue partition). To find which partition to use, go back in the Grub menu, then press c to go to the Grub command line. Then type:
 kernel (hd0,TAB
When pressing TAB, Grub will propose a list of possible partitions. Try to identify your windows primary partition from the list (usually the first ntfs partition). You can then either restart the PC, boot windows normally and edit the file menu.lst, or simply type the lines directly in the command line (e.g. assuming your windows partition is in (hd0,1)):
kernel   (hd0,1)/boot/linux vga=normal ramdisk_size=14972 root=/dev/rd/0 rw --
initrd   (hd0,1)/boot/initrd.gz
boot

Troubleshoot

Note: Log messages are visible with Ctrl-Alt-F4.

Reiserfs support

  • reiserfs is no longer supported in Ubuntu installer since 13.10.
  • Solution is to install the root partition on ext4 then convert it to reiserfs:
    • Convert ext4 to reiserfs (archive partition with tar, format fs, restore).
    • Update /etc/fstab.
    • Update /boot partition (re-install grub, re-install kernel, see Grub).

Grub

Can't install grub on USB Live / Net boot with SSD
  • Solution is to remove the USB stick. Installer confuses the stick with the SSD drive (See log messages)

Upgrade

  • Start upgrade via update-manager:
sudo update-manager -d
or via command-line
sudo do-release-upgrade
  • After upgrade, list packages that are no longer coming from official sources:
apt-show-versions | grep -v uptodate
For each of these packages, uninstall / purge if necessary, or fall-back to an official package. Avoid at all costs packages that are coming from no repositories (No available version in archive)

Ubuntu on Laptops

My log on installing Ubuntu on various Laptops:

Dell Inspiron 2650 - Lucid 10.04.3

Installation
  • I had some issues to simply launch the Ubuntu installer.
  • The laptop cannot boot from USB, and the CD i burnt with Lucid failed to start (maybe the CD was bad, or the reader lens was getting old).
  • Finally I got it working with a network boot from withing windows (see #Net boot from within Windows above)
  • During install, there was a freeze on some config screen. The screen was empty, however anything typed on the keyboard was echoed in the statusline. Finally pressing twice enter resumed the installation. Phew!
Install ssh to guarantee remote access
  • Always a good idea. However I had problem to simply get the text console. Ctrl-Alt-F1 did nothing at the login screen. I rebooted, then pressed Ctrl-Alt-F1 repeatedly, until login. This way, I could access the console:
sudo apt-get install ssh
Issue with NVidia driver
  • The laptop has an old Nvidia GeForce 2 card. Apparently this card is no longer supported in the newest version of nvidia driver (see [3]).
  • The issue observed are garbage during the gdm login screen. The screen seems ok, but then the screen is not correctly refreshed.
  • To fix that, I removed all nvidia drivers, and install the nvidia-96 one (i.e. the last one that still supports GeForce2 cards):
dpkg --get-selections nvi*
# nvidia-173-modaliases             install
# nvidia-96-modaliases              install
# nvidia-common                     install
# nvidia-current-modaliases         install

sudo apt-get remove nvidia-current-modaliases
sudo apt-get remove nvidia-common
sudo apt-get remove nvidia-173-modaliases
sudo apt-get remove nvidia-96-modaliases

sudo apt-get install nvidia-96
  • Reboot. Seems to work now!
Issue with keyboard / touchpad not working
  • The keyboard and touchpad does not work in login, but work in grub menu. This is really strange because I could swear they worked initially after installing Lucid.
  • This is probably due to an update of the kernel or a package.
  • Anyway, to fix this, simply add acpi=off at the kernel line at boot (after quiet nosplash) (see [4]). To make this setting permanent, edit /etc/default/grub followed by sudo update-grub.

HP Pavilion g6 (Marine's laptop)

Backlight off issue

When trying to boot Ubuntu Lucid Oneiric 11.10 from USB, the backlight remained off during boot and at login screen.

Solution:

  • From [5]. The following solution seems to solve backlight issue at boot/login but also after power management. At boot screen, press shift when seeing the keyboard and human logo to go to grub menu. Press F6 and select option nomodeset.
  • From [6]. At boot screen, press shift when seeing the keyboard and human logo to go to grub menu. Press F6 (or F7) and add the following options to boot line:
    • quiet acpi_osi=Linux acpi_backlight=vendor splash

    This works, but when power management turns off the screen, the backlight remains off.

  • Another solution, from [7], but it does not seem to work on that laptop: 
    sudo setpci -s 00:02.0 F4.B=00

    • Shortcut: Ctrl-Alt-Delete

Kernel

Install new kernels

There are several sources for kernel on Ubuntu:

Ubuntu Xenial

Since U16.04, the releases for the LTS Enablement Stack changed to a Rolling Update model.

The LTS HWE feature the following kernels:

  • HWE kernel.
  • HWE-edge kernel, early access to HWE kernel.

Install latest HWE kernel: 

# Desktop
sudo apt-get install --install-recommends linux-generic-hwe-16.04 xserver-xorg-hwe-16.04
# Server
sudo apt-get install --install-recommends linux-generic-hwe-16.04
Ubuntu Trusty

Install latest Utopic kernel: 

# Get Utopic kernel
sudo apt-get install --install-recommends linux-generic-lts-utopic xserver-xorg-lts-utopic libgl1-mesa-glx-lts-utopic libegl1-mesa-drivers-lts-utopic

Install latest Vivid kernel: 

# Get Vivid kernel
sudo apt-get install --install-recommends linux-generic-lts-vivid xserver-xorg-lts-vivid libgl1-mesa-glx-lts-vivid libegl1-mesa-drivers-lts-vivid
In general
Note: These instructions does not cover updating the xorg drivers, which should be updated as well on desktop.

To install a new version of the kernel:

  • Choose manually the kernel version to install. You need to install the headers and the image, for instance:
sudo apt-get install linux-headers-2.6.32-28-generic-pae
sudo apt-get install linux-image-2.6.32-28-generic-pae
Note that you might need to install one of the additional repository above if the version you request is not in your current set of repositories.
  • Install one of the meta-packages (See linux-meta) linux-* and linux-headers-*. These always points to the latest kernel versions so that you will always receive all security/serious bug updates.
sudo apt-get install linux-headers-generic-pae linux-generic-pae  # Generic PAE (for >=4GB systems)
sudo apt-get install linux-headers-generic     linux-generic      # Generic
sudo apt-get install linux-headers-virtual     linux-virtual      # For Virtual machine
sudo apt-get install linux-headers-server      linux-server       # For server
sudo apt-get install linux-headers-rt          linux-rt           # For RT kernel
sudo apt-get install linux-headers-generic-pae linux-generic-pae  # Generic PAE (for >=4GB systems)
  • Install one of the LTS backport kernels linux-image-*-lts-backport-* and linux-headers-*-lts-backport-*. These are kernel metapackages from new distribution releases that always point to the latest kernel in that release so that they are automatically updated when there is a serious kernel bug fix. For instance, on Lucid:
# Maverick backport
sudo apt-get install linux-headers-generic-pae-lts-backport-maverick linux-generic-pae-lts-backport-maverick
# Natty backport
sudo apt-get install linux-headers-generic-pae-lts-backport-natty linux-generic-pae-lts-backport-natty

These backports are available in security or updates repositories, or in the kernel PPA.

  • We can see easily dependencies between linux packages with commands:
apt-rdepends -d linux-image-generic-pae | dot -Tpng | display
apt-rdepends -rd linux-image-generic-pae | dot -Tpng | display
We can see that (at time of writing) that server kernels are actually synonyms for generic-pae kernels. We have indeed:
  • Generic Linux kernel image: linux-imager-server points towards linux-image-generic-pae
  • Generic complete Linux kernel : linux-server points towards linux-generic-pae

Remove old kernels

Removing old kernels is necessary to save space on the /boot partition, and to save space in general.

To get the currently running kernel version, run 

uname -r                                    # Get currently running kernel

Below are various solutions, in order of preference. CAUTION! If you upgraded your kernel, make sure you rebooted before trying any of the solutions below since some might fail otherwise.

References

Using Ubuntu-Tweak

Install and run Ubuntu Tweak and in Janitor, and select Old Kernel, Package Configs, and Unneeded Packages (similar to apt-get autoremove it seems)

Almighty remove all oneliner
sudo apt-get autoremove --purge 'linux-headers-[0-9].*' linux-headers-$(uname -r)+ linux-headers-$(uname -r | cut -d- -f1,2)+ 'linux-image-[0-9].*' linux-image-$(uname -r)+

This seems to be equivalent to what ubuntu-tweak is doing. However as a side-effect, it also marks the currently installed kernel as being manually installed (instead of automatically).

Manually using apt-get
uname -r                              # Get currently running kernel
dpkg -l | grep linux-image-           # Get the list of installed kernel
sudo apt-get autoremove linux-image-2.6.32-22-generic linux-image-2.6.32-21-generic  # Remove kernels
This only removes linux-image / linux-header packages. Another solution is to match on the kernel version:
sudo apt-get remove --purge 2.6.28-11-*     #to remove kernel 2.6.28-11
sudo apt-get purge 2.6.28-11-*              #equivalent
But this command might remove any package matching the kernel version so this is not ideal.
Using bikeshed package

Use script purge-old-kernels from bikeshed package

Is script correct? [8]
Using apt-get
sudo apt-get autoclean
sudo apt-get clean
sudo apt-get autoremove
1st command does nothing (no kernel removed)
2nd command clears the apt cache
3rd command needs '--purge' to purge all config files, etc. It does not remove old kernels.

Troubleshoot

CIFS shares not properly unmounted during shutdown

When shutting down the PC with Samba (CIFS) shares mounted, the shutdown sequence hangs with the following error messages: 

CIFS VFS: server not responding
CIFS VFS: no response for cmd 50 mid xxx

This is apparently a bug that is creeping in Ubuntu since a long time ago. Basically there are 2 possible fixes (as in [9], [10], [11]):

The one I use, proposed by Daniel Ellis here [[12]]: 

sudo mv /etc/rc0.d/S31umountnfs.sh /etc/rc0.d/K31umountnfs.sh
sudo mv /etc/rc0.d/S40umountfs /etc/rc0.d/K40umountfs
sudo mv /etc/rc6.d/S31umountnfs.sh /etc/rc6.d/K31umountnfs.sh
sudo mv /etc/rc6.d/S40umountfs /etc/rc6.d/K40umountfs

Another one (not tried yet): 

sudo ln -s /etc/init.d/umountnfs.sh /etc/rc0.d/K15umountnfs.sh
sudo ln -s /etc/init.d/umountnfs.sh /etc/rc6.d/K15umountnfs.sh

Troubleshooting 'System program problem detected'

  • We may get this message while logging in. This message indicates that a system program crashed, but unfortunately there are no other details.
  • We look at var/crash/ to get more information. There we see a file named _usr_sbin_aptd.1000.crash.
  • Opening the file we see
...
ExecutablePath: /usr/sbin/aptd
...
ProcCmdline: /usr/bin/python /usr/sbin/aptd
...
DBusException: org.freedesktop.DBus.Error.AccessDenied: Connection ":1.90" is not allowed to own the 
service "org.debian.apt" due to security policies in the configuration file
  • So basically the program aptd cannot run because user do not have the right permission. aptd is used to allow package management from user space.
  • The policy file is /etc/dbus-1/system.d/org.debian.apt.conf. File format is given by dbus-daemon manual page. We can fix the policy issue as follows:
--- a/dbus-1/system.d/org.debian.apt.conf

  • However that fix might open a security vulnerability. Checking the history of the file org.debian.apt.conf, we see that there was no change in that file since last install, and so the fix above is most probably not the correct one.

MacBuntu 10.04

The mighty Macbuntu 10.04 theme! Reverted changes:

  • Fonts — see below.
  • Terminal — Colors select Use colors from system theme (was set to Gray on black built-in schemes). Keep transparent background 95%.
  • Panel — add back System Monitor. We don't add back the bottom task panel.
  • In Configuration Editor, /apps/metacity/general/button_layout: menu:minimize,maximize,close
  • Appearance
    • (before Macbuntu) Fonts — Application → Tahoma 9; Document→ Sans 8; Desktop → Sans 8; Title → Sans Bold 9; Fixed width → Monospace 8
    • (after Macbuntu) Fonts — Application → Lucida Grande 9; Document→ Lucida Grande 9; Desktop → Lucida Grande 9; Title → Lucida Grande 10; Fixed width → Lucida Console 9 (originally Lucida Console 10)
    • Fonts — rename ~/.fonts.conf to ~/.fonts.conf.macbuntu to disable macbuntu hinting settings override.
  • Appearance
    • Wallpaper, edit as necessary.
  • Keyboard Layout (System-Wide)
    • Layout: Belgium (default) + USA, no separate layout
      Custlayout Belgium (file /usr/share/X11/xkb/symbols/be) to allow AltGr-; → '<' and AltGr-: → '>', and support Greek letters with AltGr-Shift.
    • Options: Capslock as an additional ESC key,
    Alt+CapsLock or Right Ctrl+Right Shift switch layout ((because Alt+Shift,Left Ctrl+Left Shift prevents ctrl-alt-shift shortcuts to work, Right Ctrl conflicts with VirtualBox)) disable layout switching, right alt chooses 3rd level.

    Super-E Home Folder Hack Super is mapped to Win keys not needed anymore it seems
