2023-01 update

Done on 2023-01-19

Original plan: upgrade mercury from Debian 9 "stretch" to 10, "buster."

#nslug denizen joeDoh convinced me to then do 10 --> 11, "bullseye".

stretch --> buster instructions here

buster --> bullseye here

Output of dpkg --get-selections "*" below

• add line to /etc/apt/sources.list
• in /etc/apt/sources.list.d/ , change all references to stretch, to buster
• script -t 2>~/upgrade-busterstep.time -a ~daniel/upgrade-buster01.script
• changed package states in /var/log/apt/history.log
• > locale: Cannot set LC_ALL to default locale: No such file or directory
• Configuration file '/etc/security/access.conf' ==> Modified (by you or by a script) since installation.

After reboot

• the Perl libraries are *all* gone? - no, just some.

Now do 10 --> 11 with https://www.cyberciti.biz/faq/update-upgrade-debian-10-to-debian-11-bullseye/

Fix Sequence

1. [x] apache2 just came up
2. [x] mariadb just acme up
3. [x] solarns.ca wayves.ca just came up
4. [x] gay.hfxns.org needed Perl DateTime which took like an hour of Perl dependency installs
5. [x] put old /etc/ssh/sshd_config in
6. [x] Perl DateTime
7. Check HRE again
8. check the rover thing that tests if certs are available. Needed Date::Parse
9. [x] Perl Date::Parse RRD::Simple CPAN::DistnameInfo inc::latest
10. dovecot imap-login: Error: Failed to initialize SSL server context: Can't load DH parameters (ssl_dh setting): fixed by deleting /var/lib/dovecot/ssl-parameters.dat
11. [x] check sshd/ssh
12. [ ] fail2ban is really fucked up. the config files have changed so much from when it was installed that they can't be re-used. I copied /etc/fail2ban and did a "purge" and then started adding stuff back in.
13. [x] CPAN force install RRD::Simple because of nan / -nan errors
14. [x] apt remove php7.4*; this was a mistake because it looks like drupal 7 and 8 need 7.2 and drupal 10 needs 8.2. had to reinstall 7.4 and php7.4-mysql and php7.4-xml
