Editing revision 8 of 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". [https://www.debian.org/releases/buster/amd64/release-notes/ch-upgrading.en.html stretch --> buster instructions here] [https://www.cyberciti.biz/faq/update-upgrade-debian-10-to-debian-11-bullseye/ 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/ grub-install: warning: Embedding is not possible. GRUB can only be installed in this setup by using blocklists. However, blocklists are UNRELIABLE and their use is discouraged.. ===Fix Sequence=== # [x] apache2 just came up # [x] mariadb just acme up # [x] solarns.ca wayves.ca just came up # [x] gay.hfxns.org needed Perl DateTime which took like an hour of Perl dependency installs # [x] put old /etc/ssh/sshd_config in # [x] Perl DateTime # Check HRE again # check the rover thing that tests if certs are available. Needed Date::Parse # [x] Perl Date::Parse RRD::Simple CPAN::DistnameInfo inc::latest # 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 # [x] check sshd/ssh # [ ] 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. # [x] CPAN force install RRD::Simple because of nan / -nan errors # [x] apt remove php7.4* # Deleted php7.4; this was a mistake because it looks like drupal doesn't run under 8.2. had to reinstall 7.4 and php7.4-mysql and php7.4-xml
