Debian 12 Transition
Upgrade steps
1. Create the /etc/apt/keyrings folder.
2. Download the CSC keyring into it:
wget -O /etc/apt/keyrings/csclub.gpg http://debian.csclub.uwaterloo.ca/csclub.gpg
3. Make sure that the CSC keyring is the only one in /etc/apt/trusted.gpg:
gpg --no-options --show-keys /etc/apt/trusted.gpg
4. Delete /etc/apt/trusted.gpg and its backup file:
rm -f /etc/apt/trusted.gpg /etc/apt/trusted.gpg~
5. Replace the old-style /etc/apt/sources.list and /etc/apt/sources.list.d/*.list files with the new Deb822 "sources" style (see /etc/apt/sources.list.d/*.sources on sorbitol; don't copy the one for the Dell repo). Add a helpful note in /etc/apt/sources.list for other syscom members:
# See /etc/apt/sources.list.d/*.sources
6. apt update && apt dist-upgrade
7. apt autoremove --purge
8. During the upgrade, accept the new configuration files (choose the 'Y' option) for the following files:
- /etc/fail2ban/fail2ban.conf
- /etc/fail2ban/jail.conf
- /etc/fail2ban/filter.d/sshd.conf
Everything else should keep the old file.
9. Copy the following files from sorbitol:
- /etc/fail2ban/fail2ban.local
- /etc/fail2ban/jail.local
- /etc/fail2ban/filter.d/sshd.local
Then restart fail2ban.
10. If the 'ntp' package is installed, purge it and install systemd-timesyncd instead. Enable the systemd-timesyncd service and copy /etc/systemd/timesyncd.conf.d/csclub.conf from sorbitol. Start the service and make sure it's working.
11. Get rid of python2 if it's still installed:
apt purge python2.7-minimal apt autoremove --purge
Pending machines
