- Upgrade mercury Debian 11 (bullseye) to 12 (bookworm)
- then from 12 to 13 (trixie)
Did not come back up:
Perl version upgraded so had to upgrade ALL of the packages... this took a couple hours:
- cpanm install ...
- CPAN::DistnameInfo
- CPAN::Meta::Prereqs
- DateTime
- --force RRD::Simple
- find / -name CPAN -ls
fail2ban
- rm filter.d/ignorecommands/apache-fakegooglebot filter.d/apache-fakegooglebot.conf and its reference in jails.local
- set jails.local vsftpd to false
postfix & dovecot
- it was a mistake to keep the old config files. I should have installed the new config files and set up a fresh configuration
