--- Comment #10 from Gordon Messmer gordon.messmer@gmail.com --- I wasn't previously aware of the "--enable-network" flag for mock. However, that's not enough to allow the tests to run. The build log includes:
Error: error running newgidmap: exit status 1: newgidmap: write to gid_map failed: Operation not permitted
I'll continue to look into that for a while (unless there are known solutions for using rootless container tools in mock). I see that the mock environment includes values for mockbuild in /etc/sub[ug]id, so I'm actually surprised that this doesn't work.
