I see there is already a question very similar to mine, but with a slightly different issue. I hope this will not break any rules.I have a web server running a LEMP stack where I upgraded Ubuntu from 20.04 LTS to 22.04 LTS. Everything works fine except that PhpMyAdmin is no longer working. I reinstalled the PhpMyAdmin package and it went without issues or warnings but it still does not work.I did check nginx, PHP, Mariadb and they are all running. The only one not started is Apache2 as can be seen as the output of sudo systemctl status apache2.service -l --no-pager.
