createLiveMedia problems with mock-1.4.8

[John Florian]

I have found that since upgrading mock on my sole builder for doing
livemedia tasks that these tasks no longer work.  Previously, I had
mock-1.4.6-1.fc26 with no problems, but mock-1.4.8-1 causes issues.

Digging around the logs for a failed livemedia task is always fun
because lots of errors are normal, but not fatal.  However, I see in
anaconda-anaconda.log messages to the effect that "The group 'core' is
required for this installation. This group does not exist. This is a
fatal error and installation will be aborted."  I think the real cause
though is revealed in anaconda-dnf.librepo.log where I see "Curl error
(6): Couldn't resolve host name for http://hostname..." which stems
from the "url --url=http://hostname..." directive in my kickstart.

I see in the release notes for 1.4.7 and 1.4.8 mentions about changes
related to how network connectivity is affected in the build roots, but
 those seem relevant only to systemd-nspawn.  Since koji-1.15 hasn't
made it's way to CentOS or Fedora repos yet, I'm still on 1.14 and so
necessarily have a tag option "mock.new_chroot : False" set.  To
overcome the issues with upgrading to mock-1.4.8, I've also tried
adding "mock.rpmbuild_networking : True" and "mock.use_host_resolv :
True" but still the build root is preventing name resolution.

Any ideas?

Full log will help.

Are you able to build the package in Copr? With network enabled and disabled?

Not a package -- this is livemedia.  I've never built anything in Copr,
only in our private Koji instance.  Network is enabled on the Koji
builder, of course.  Whether or not it's enabled in the mock chroot I
can't say.  With mock-1.4.6 (and apparently 1.4.7 too from more recent
tests), I'd say it has to be enabled in the mock chroot as I don't see
how the task could complete otherwise.  With 1.4.8, it seems it is
disabled, though I don't understand why.
