New - Using Let's Encrypt

Follow certbot guide.
New — We install only version from jessie-backports:

apt install python-certbot-apache=0.10.2-1~bpo8+1
# sudo apt-get install python-certbot-apache -t jessie-backports
certbot --authenticator=webroot --installer=apache

TODO — See IMPORTANT NOTES below:

IMPORTANT NOTES:
 - Congratulations! Your certificate and chain have been saved at
   /etc/letsencrypt/live/www.immie.org/fullchain.pem. Your cert will
   expire on 2016-10-02. To obtain a new or tweaked version of this
   certificate in the future, simply run certbot again with the
   "certonly" option. To non-interactively renew *all* of your
   certificates, run "certbot renew"
 - If you lose your account credentials, you can recover through
   e-mails sent to m-certbot@immie.org.
 - Your account credentials have been saved in your Certbot
   configuration directory at /etc/letsencrypt. You should make a
   secure backup of this folder now. This configuration directory will
   also contain certificates and private keys obtained by Certbot so
   making regular backups of this folder is ideal.
 - If you like Certbot, please consider supporting our work by:

   Donating to ISRG / Let's Encrypt:   https://letsencrypt.org/donate
   Donating to EFF:                    https://eff.org/donate-le

Now all certificates are stored in a single file. Same for the key:

SSLCertificateFile      /etc/letsencrypt/live/www.immie.org/fullchain.pem
SSLCertificateKeyFile /etc/letsencrypt/live/www.immie.org/privkey.pem

Update - Add some issue with certbot

Jun 12 00:38:12 prime certbot[9567]: File:
Jun 12 00:38:12 prime certbot[9567]: - Could not be found to be deleted /var/lib/letsencrypt/icJA1m-EoE3Gsf6HJlITR4GCBb_9wvlyYV4faqJ_aVk.pem - LE probably shut down unexpectedly
Jun 12 00:38:12 prime certbot[9567]: File:
Jun 12 00:38:12 prime certbot[9567]: - Could not be found to be deleted /var/lib/letsencrypt/icJA1m-EoE3Gsf6HJlITR4GCBb_9wvlyYV4faqJ_aVk.crt - LE probably shut down unexpectedly
Jun 12 00:38:13 prime certbot[9567]: Attempting to renew cert from /etc/letsencrypt/renewal/www.immie.org.conf produced an unexpected error: 'module' object has no attribute 'rand'. Skipping.

Uninstalled certbot completely, and removed all files (/etc/encrypt, /var/...).
Reinstall with standalone server (did not try webroot as done before, maybe that would work) [2].

certbot --authenticator standalone --installer apache --pre-hook "systemctl stop apache2" --post-hook "systemctl start apache2"

Update - Yet more issue (on immie.org, but not on noekeon.org).

See issue #5111. I get error 'module' object has no attribute 'rand'.
As a fix, revert back to apache plugin renewal, and removed pre-/post-hook. File

[renewalparams]
authenticator = apache
account = 157b05fb0f012e07716c9dbdc3a9f923
installer = apache

Then temporarily fix /usr/lib/python2.7/dist-packages/acme/crypto_util.py. Changes:

+import os

-    cert.set_serial_number(int(binascii.hexlify(OpenSSL.rand.bytes(16)), 16))
+    cert.set_serial_number(int(binascii.hexlify(os.urandom(16)), 16))

In fact I noticed that immie.org had a newer version of python-openssl:

ii  python-openssl                     16.0.0-1~bpo8+1       # On noekeon.org
ii  python-openssl                     18.0.0-1              # On immie.org

So let's downgrade, and hope it will fix the problem:

apt install python-openssl=16.0.0-1~bpo8+1

... still not fixed. We need to downgrade more packages (list obtained by comparing dpkg output on reference server):

sudo apt install python-cffi-backend=1.9.1-2~bpo8+1 python-cryptography=1.7.1-3~bpo8+1 python-idna=2.0-3~bpo8+1 \
    python-mock=2.0.0-3~bpo8+1 python-pkg-resources=33.1.1-1~bpo8+1 python-pyasn1=0.1.9-1~bpo8+1 \
    python-setuptools=33.1.1-1~bpo8+1 python-six=1.10.0-3~bpo8+1 python-pbr=1.8.0-4.1~bpo8+1

Update - 2019 Jan - tls-sni-01 challenge no longer supported

Received mail for immie.org telling tls-sni-01 is no longer supported, and that I must switch to either http-01 or dns-01. Checking with certbot renew --dry-run indeed confirm that I'm using tls-sni-01 as challenge method.
Tried many things, but none seems to work. In fact, my certbot is too old

certbot --version
# certbot 0.10.2   <--- too old, we need at least 0.28

On Debian Jessie, the recommended install now is to use certbot-auto [3].
First remove old certbot:

apt remove certbot

Install certbot-auto:

cd /usr/local/bin
wget https://dl.eff.org/certbot-auto
chmod a+x certbot-auto
# Let's try
/usr/local/bin/certbot-auto renew --dry-run

It works, so we change the cronjob task as follows:

0 */12 * * * root test -x /usr/local/bin/certbot-auto -a \! -d /run/systemd/system && perl -e 'sleep int(rand(3600))' && /usr/local/bin/certbot-auto -q renew

Update - 2019 Jan - urn:ietf:params:acme:error:unauthorized: : The client lacks sufficient authorization

certbot-auto fails on noekeon.org, with error The client lacks sufficient authorization.
We can debug the process with --debug-challenges (see this page for details on how certbot updates apache2 config for the test).

/usr/local/bin/certbot-auto certonly --dry-run --debug-challenges
# ...
# - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

# challenges.
# - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

Now let's try to connect.

wget http://keccak.team/.well-known/acme-challenge/VtSysECebfgnfMgpCbXMz4wzgyXqMc0qBAVd5DB2GJ8
# --2019-01-21 08:59:43--  http://keccak.team/.well-known/acme-challenge/VtSysECebfgnfMgpCbXMz4wzgyXqMc0qBAVd5DB2GJ8

# HTTP request sent, awaiting response... 403 Forbidden
# 2019-01-21 08:59:43 ERROR 403: Forbidden.

Checking Apache2 log /var/log/apache2/error.log, we get an search permissions missing error

... (13)Permission denied: [...] AH00035: access to /.well-known/acme-challenge/... denied (filesystem path '/var/lib/letsencrypt/http_challenges') because search permissions are missing on a component of the path

Searching on the internet, we see this is due to wrong permissions on some directory in the path. Indeed, the culprit is /var/lib/letsencrypt:

l /var/lib
# drwx------ 5 root      root     4.0K Jan 21 08:06 letsencrypt/

Fix the permissions to solve the issue:

sudo chmod 755 /var/lib/letsencrypt/

April 2019 —

Doing a certbot-auto renew --dry-run fails on noekeon.org, with following error:

main: imap.noekeon.org
Type:   connection
Detail: Fetching
http://www.noekeon.org.well-known/acme-challenge/tPzDt_Jjn802jApS1X7O7yrfEGcmGUlNxsi4AQltOVQ:
Invalid hostname in redirect target, must end in IANA registered
TLD

As we see, it seems there is a missing slash / before .well-known in the URL.
The problem is in the apache config, where the selected text come here file apache2/sites-available/noekeon.org.conf

cd /etc
ag www.noekeon.org
# apache2/sites-available/000-default.conf
# 16:  # Redirect everybody to http://www.noekeon.org
# 17:  Redirect "/" "http://www.noekeon.org"

We must add a trailing slash:

-       Redirect "/" "http://www.noekeon.org"
+       Redirect "/" "http://www.noekeon.org/"

September 2023

Upgrade to bookworm
We revert to distribution's certbot.

rm /usr/local/bin/certbot-auto
rm -rf /opt/eff.org/
apt install certbot python3-certbot-apache

Upgrade all HTTP site to HTTPS.

certbot -d radiogatun.noekeon.org --apache      # Add certificate to a given domain (only)

Note with ServerAlias

If using server alias, make sure to request all certificates at the same time [4]:

# <VirtualHost *:80>
#     ServerName www.example.com
#     ServerAlias example.com
#
#     ServerAdmin webmaster@localhost
#     DocumentRoot /var/www/www.example.com/public_html
# </VirtualHost>

./letsencrypt-auto --apache -d www.example.com -d example.com

When doing this, we had an issue with a missing CAA field (see here for more info) in the DNS configuration:

certbot --apache -d ober.noekeon.org -d mail.noekeon.org -d imap.noekeon.org -d smtp.noekeon.org -d pop.noekeon.org
# Saving debug log to /var/log/letsencrypt/letsencrypt.log
# Requesting a certificate for ober.noekeon.org and 4 more domains
# 
# Certbot failed to authenticate some domains (authenticator: apache). The Certificate Authority reported these problems:
#   Domain: imap.noekeon.org
#   Type:   dns
#   Detail: DNS problem: networking error looking up CAA for noekeon.org
# 
# Hint: The Certificate Authority failed to verify the temporary Apache configuration changes made by Certbot. Ensure that the listed domains point to this Apache server and that it is accessible from the internet.

To fix that, we add the following field in OVH DNS config (@ means empty field, ie. configuration valid for all domain):

@ IN CAA 0 issue "letsencrypt.org"

Certbot cron not running

On noekeon.org, the cron service was not running.
... turns out the cron line is disabled when systemd is detected.
... turns out the certbot.timer was disabled in systemd as well (/etc/systemd/system/certbot.timer symlinked to null)

systemctl enable certbot.timer
systemctl start certbot.timer

Administration

~~Use webmin control panel: https://www.immie.org:10000/ (see Webmin page for usage).~~

I don't use webmin anymore (never used in fact). All administration is done via SSH command line.
