Upgrade from Debian 10 to Debian 11 Apache PHP mismatch

Hi,
I have updated my Debian 10 to Debian 11 by following the instuctions on How to Upgrade from Debian 10 to Debian 11. During the upgrade, I chose to accept the new jk-init.ini. After the reboot, I tried to run ISPConfig but it failed. When I checked the logs, I saw that Apache2 was not starting because it was still looking for PHP 7.3 libraries. and afterwards started with Update the ISPConfig Perfect Server from Debian 10 to Debian 11 . When I came to step '5. Update paths to use PHP 7.4 as default PHP version', I could not run ISPConfig. When I checked the logs, I realized that the Apache2 version 2.4.61 was still looking for older PHP version and failing. Have I done something obvious in Upgrade from Debian 10 to Debian 11? Thanks in advice for any ideas!
Regards.

 

Thanks a lot for your reply!
Do you mean the Step '4. Run a force update of ISPConfig' in Update the ISPConfig Perfect Server from Debian 10, ? If so, I have run
ispconfig_update.sh --force .

What do you mean by run ISPConfig?
I too had problems with PHP when upgrading Debian 10 to 11. But I did manage to solve them in December.
You should do https://forum.howtoforge.com/threads/please-read-before-posting.58408/ to rule out the usual suspects.

 

My apologies!

Thank you for your reply.
I do not think that my problem is related to ISPConfig. I think I have an Apache2 problem due to Debian-10 to 11 upgrade. When I typed localhost://8080 in the browser, I get blank screen with "Firefox can’t establish a connection to the server at localhost:8080". I think it does so because Apache2 does not start. When I check the logs, I see that Apache2 is looking for old version of PHP:
When I restart Apache2 on command line, the journalctl output has:

Code:

Aug 29 17:58:01 myHost systemd[1]: apache2.service: Control process exited, code=exited, status=1/FAILURE

This was also the situation after the first step: Upgrade from Debian 10 to Debian 11 . What happened is, during the execution of full upgrade (apt-get full-upgrade -y) step, the Screen Saver has crushed on me. I followed the instructions to unlock it. When I unlocked it, I entered the command apt-get full-upgrade -y again. But it complained that there was already a process running. I was not sure if it was really running in the background or hanging. After a while, I killed it and reissued apt-get full-upgrade -y. It seemed to complete normally. I wonder if something went wrong there.

Indeed! Now I know!
It worked.
Thank you very much!
