Hi, I run ispConfig on a container, and did an update from stretch to buster yesterday on a copy and it "seemed" to work. So this morning I confidently did the same on the production container. Since I'm posting here, you already know it is a disaster... What I did: After reboot nothing, absolutely nothing is running, apache example: Here is an abstract from syslog: UPDATE: Well... restarted manually apache worked, To be sure, I rebooted and guess what? it works now... I hate when things are not stable, and I'm sure it will bite me again later... UPDATE 2: not sure it is related, but I received a mail dated to the first failure: a diff between the two files confirmed that they are identical of course...
Just to be sure, check the /etc/apache2/apache2.conf file, It might contain two includes for the sites-enabled directory now (towards the end). There should be just one. That's probably a false positive, caused by the first apache failure.
thank you for the idea, I didn't check that. Fortunately (or not as that could have been the culprit), there is just one include there:
