CyberPanel Installation Fails on Ubuntu 22.04 Due to Invalid MariaDB MaxScale Repository (404 Error)

Description:
I am trying to install CyberPanel on a fresh Ubuntu 22.04 (Jammy) server, but the installation consistently fails during the apt-get update step.

The issue is caused by an invalid MariaDB MaxScale repository that returns a 404 error and breaks the entire installation process.


Error Log:

E: The repository 'https://dlm.mariadb.com/repo/maxscale/latest/apt jammy Release' does not have a Release file.
404 Not Found

This causes:

apt-get update failed with return code: 100

What I Observed:

  • The repository https://dlm.mariadb.com/repo/maxscale/latest/apt is automatically added during installation.
  • Even after manually removing the repo file from /etc/apt/sources.list.d/ , it gets recreated when running the installer again.
