If anyone wants to try a Mint template, you can pick up a pre-built
ulyssa from https://qubes.3isec.org/Templates
This is well loaded with a good selection of software.
It’s also preconfigured to use the focal repository at
https://qubes.3isec.org/.
Because Mint is Ubuntu based, and the relevant packages are installed,
the usual Qubes tools are available.
Download the template to a Fedora based disposableVM.
The template package is signed with my Qubes Signing key- you can get a
copy of this online and check the signature against the mailing list,
github etc.
Once you are happy that you have a genuine key, you can check the
signature on the package:
rpm -K <template>
The output should show pgp md5 OK
If you are satisfied, then you can copy the package to dom0 and install
it:
qvm-run -p <disposableVM> 'cat <path-to-package>' > <package>
And install it using rpm -i ..
Better would be to process it in a managementVM if you have one
configured.
If you need help with the template, or want to build one for yourself,
(better), just ask
