Hello. I'm trying to install ISPconfig on the debian 11 and I've getting the following errors: I'm running latest mariadb 10.6 and php 8.1. Any ideas? I've followed standard perfect server, LAMP stack.
You can not change PHP version of the OS. Install default Debian 11, do not change PHP version or install extra PHP or mariadb packages. Then preferably use ISPConfig auto installer: https://www.howtoforge.com/ispconfig-autoinstall-debian-ubuntu/ If you need additional PHP versions, you can install them and choose per website what PHP that website uses. The autoinstaller installs additional PHP versions.
