[user@fedora-26 ~]$ sudo dnf update && sudo dnf distro-sync && sudo dnf upgrade && sudo poweroff
Error: Failed to synchronize cache for repo 'updates'

Ah, this is a result of changing the Template for 'sys-whonix' from whonix-gw-13 to whonix-gw-14

Why is this a problem?

I would like to use Whonix 14 as my update proxy.
