There appears to be a discrepancy between the Virtualmin website and the information published on GitHub regarding supported Grade A systems.
According to GitHub, the following operating systems are listed as Grade A:
Red Hat Enterprise Linux and derivatives
AlmaLinux and Rocky Linux 8, 9, and 10 on x86_64 and aarch64
RHEL 8, 9, and 10 on x86_64 and aarch64
Debian Linux and derivatives
Debian 11, 12, and 13 on i386, amd64, and arm64
Ubuntu 20.04, 22.04, and 24.04 on i386, amd64, and arm64
However, the Virtualmin website currently lists support for:
Debian 11 and 12 on i386 and amd64
Ubuntu 22.04 LTS and 24.04 LTS on i386 and amd64
Rocky Linux, AlmaLinux, and RHEL 8 and 9 on x86_64
Could you clarify whether the additional versions and architectures listed on GitHub are already officially supported and the Virtualmin website has not yet been fully updated, or if there is another explanation for this mismatch?
Without hunting it down on GitHub, are you sure that doesn’t refer to the upcoming release? The default is ‘master’ which I think is development version.
So, if I’m not completely off base, the master branch of virtualmin-install is 8.0.4, and Debian 13 is listed as the grade A system.
However, as far as I know, the admins announced shortly before the turn of the year that version 8 was in the starting blocks. I haven’t yet received any information that version 8 has already been officially released.
