Don't use it. Use dnf or apt from within your Fedora or Debian
(respectively) template to install packages.

One of the repos appears to be having trouble. Try again tomorrow.

Increase your AppVM's private storage space. See the Qubes docs for
howto details if needed.

Apart from the repo having trouble, none of these are bugs- they are
just the way Qubes works. You're right, debug mode won't really help for
that. It might help if you read through the documentation to get a
better understanding of what Qubes is doing, and why. Also, searching
this mailing list and/or qubes-issues can often provide resolutions to
commonly encountered difficulties.
