Administration
Remove old kernels from GRUB
To remove old kernel entries in GRUB ([1] and [2], or other sol [3])
sudo apt-get remove --purge 2.6.28-11 #to remove kernel 2.6.28-11
Medibuntu
To install the Medibuntu repositories (see here)
sudo wget http://www.medibuntu.org/sources.list.d/`lsb_release -cs`.list --output-document=/etc/apt/sources.list.d/medibuntu.list && sudo apt-get -q update && sudo apt-get --yes -q --allow-unauthenticated install medibuntu-keyring && sudo apt-get -q update
Troubleshoot
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 [4], [5], [6]):
The one I use, proposed by Daniel Ellis here [[7]]:
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
