These issues happen particularly with “updates” repositories. I think this is
because you are hitting issues with poor mirroring.
They are reported by users not using apt-cacher-ng.
I find in many cases that simply retrying at a later time will work - my
guess is that this is because the mirrors have synced and no other
updates have been pushed in the mean time.
Let me know how you get on.
I see that worked for you.
I’m sure this is because of mirror syncing in fedora.
You could get round this by pointing all the Fedora repo calls to a
single server - you do this in the Remap definition. I don’t recommend
that.
Of course, in the associated GitHub discussion,
there are many options, including squid.
I find squid over baked for the purpose, and apt-cacher-ng works well
with minimal overhead. YMMV
I never presume to speak for the Qubes team.
When I comment in the Forum or in the mailing lists I speak for myself.
I’ll check it out, as I’ve got one qubes system so far (laptop), but am going to repurpose a server to be my new workstation. Plus I’ve got multiple VMs that would benefit from the rpm/deb caching.
I used to run local repos, but that ended up being even more traffic as I was caching packages I’m not using.
