Screen sharing works again in Firefox on an X1 Carbon with this update

So nice to have zchunk working again!

Sorry, just realized the command should be: dnf --enablerepo=rawhide list updates; rm /var/cache/dnf/rawhide*.solv*; rm /var/cache/dnf/rawhide-*/repodata/repomd.xml; dnf --enablerepo=rawhide list updates

Tested with zchunked rawhide repo and everything works correctly. If you want to test that it fixes the segfault, run: dnf --enablerepo=rawhide list updates; rm /var/cache/dnf/rawhide*.solv*; /var/cache/dnf/rawhide-*/repodata/repomd.xml; dnf --enablerepo=rawhide list updates

The second time you run dnf, the Rawhide repo should be about 242KB instead of the usual 55MB, but, most importantly, you shouldn't get a segfault.

The librepo update segfaults when using zchunk metadata: https://bugzilla.redhat.com/show_bug.cgi?id=1694411

@pkratosh, it looks like this won't automatically be pushed, even though the karma has been reset and there isn't any remaining negative karma. Since we're at +6, could you please push manually?

Still works perfectly

Still works perfectly

Tested with dnf group list with a test repository with zchunked updateinfo.xml.zck, and everything worked perfectly.

With vlc-3.0.5-14 in RPM Fusion, this fixes the crash in #1642729.

Tested on a FreeIPA server, and named-pkcs11 starts and works perfectly

Unfortunately, it's only testable on rawhide for the moment. See https://www.jdieter.net/posts/2018/12/24/zchunk-repodata-in-rawhide

Ok, changing my karma to +1 because the problem lies in a F27->F28 upgrade. A new install doesn't see this problem.

To fix the bug if you've done a F27->F28 update, change all the files in /var/log/nginx to have owner.group of root.root.
