After being nagged for months that Debian 11 was no longer supported, I finally bit the bullet and used a long weekend to start upgrading my cloud server.
Overall it went smoothly, as expected with Debian.There was the usual merging-in of various configuration files with the updated package-maintainers versions compared to my own modified versions, but apart from taking time there were no major surprises.
I did have two issues though:
- Owncloud
- LDAP
Owncloud
This one was mostly my own fault.
I performed the system upgrade first, which upgraded PHP from 7.4 to 8.2. This resulted in the ancient version of Owncloud that I was running in no longer running, as it did not support PHP 8.2. I should have upgraded Owncloud before upgrading the server.. Something to remember for next time!
A fair amount of muddling about and I managed to install PHP7.4 and the various dependencies which Owncloud needs from a third-party repository in order to finally manage to run the manual upgrade process.
Still couldn’t log in though as LDAP was broken..
LDAP
Debian 12 upgraded OpenLdap to version 2.5 from 2.4. This included some breaking changes, which required manually editing the backed-up LDAP data before being able to import it again.
Various websites gave some information, but in the end, the README which was installed on the server itself ended up being the best resource, and I was finally able to re-import my LDAP data.
