Hi, I was trying to update my server from ubuntu 20.04 to 22.04 with the command ‘‘do-release-upgrade’’ but after the update is done, I can’t access my website. It gives errors either ‘‘error establishing database connection’’ or 500 internal server error’'. When I was starting the update, I’m getting a lot of ‘‘no candidate ver’’ lines which I think might be related to the site not working after the update is done.

Hi there,
It is often the case with such major OS upgrades that some of the packages that were available with the old OS version are no longer available with the new version.
For example, if PHP 7.4 was the default available version with Ubunutu 20.04 it is possible that the new default version with Ubuntu 22.04 is now PHP 8.0.
What you need to do is to check your Apache error log and see what the actual problem is rather than the generic 500 error that you are seeing.
You can follow the steps here on how to troubleshoot common Apache problems:

Feel free to share the output of the logs here so I could advise you further!
Best,
Bobby
