Cannot Install Cloudron: Package 'mysql-server-5.7' has no installation candidate

[Korishan]

I have tried several times to install Cloudron, but it just won't work. I even installed on a new install of Ubuntu Server 21.04.

Every time I run the script, I get the following error in the log:

Package mysql-server-5.7 is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
However the following packages replace it:
  mariadb-test mariadb-server-10.5

E: Package 'mysql-server-5.7' has no installation candidate

I have even manually installed mariadb-server, and it still won't install. I can not imagine that Cloudron would require such an antiquated version of mysql to be installed to function.

Looking through Google, I see only a few posts about this issue, and the only reply/fix was to install an older version of Ubuntu and manually installed MySQL 5.7. That doesn't seem to be the correct solution to this problem.

Is there some arguments I can pass on the command line to get it to install with the current version of mysql or mariadb?

Cloudron only supports running on the LTS releases of Ubuntu, which would mean Ubuntu 20.04 at the time of writing this.
