I downloaded the fedora-2
6-minimal to replace the fedora-2
5-minimal.
replacing my sys-firewall equivalent the connected AppVMs can no
longer connect to the internet. If I return to the fedora-25-minimal
template, everything is working fine again.
Is there an issue with the fedora-26-minimal template that you
provide?
There was no issue migrating from 24-minimal to 25-minimal and
according to
https://www.qubes-os.org/doc/templates/fedora-minimal/
the minimal template can be used as a sys-firewall without any
changes
