Today we have encountered a dnf issue on all of our FC24/25 slaves. It affected all Jenkins jobs that are running on these slaves.

If you see this error message:

system-python: /builddir/build/BUILD/hawkey-0.6.3/src/sack.c:354: load_ext: Assertion `ret == 0' failed

please be patient. We are working to solve this issue in the next couple of minutes.

It was basically a fedora mirror issue. They have a bug on it but looks like they have already fixed it.

Thanks

Gil
