Virtualmin 7 beta install error

SYSTEM INFORMATION
OS type and version Ubunutu 20.04
Virtualmin version Not installed

The script vm7-beta-install.sh runs but exits with error:

The repository ‘Index of /vm/7/gpl/apt virtualmin Release’ does not have a Release file.
Downloading repository metadata: [2022-08-01 05:06:50 CEST] [ERROR] Failed with error: 100

Any way to bypass this?

PS: Installed virtualmin with the normal install.sh script. But even on Ubuntu 20.04 it installs MySql server not MariaDB. How do we get MariaDB database server on Ubuntu 20.04?

a quick google shows up with this:

Could you check if that iis the same problem you see in the log, and if the fix suggested also works for you and report back the results?

The problem here started with:
The repository ‘Index of /vm/7/gpl/apt virtualmin Release’ does not have a Release file.

Maybe this beta is to be used on Ubuntu 22.04 and not 20.04?

You can only get MariaDB with Ubuntu by using Virtualmin 7 beta install script.
