Will look at this. you need to add db.conf.releasever = None just before db.read_all_repos() and it will work as root still not working after implementing above in code. The code sleeps forever when run as root.
I then after 2 min interrupted code and trace back is

I run modified code thrice and it sleeps forever.
You have to wait a little longer, if dnf does a full cache refresh, it take around 4-5 min. You can check my dnf API samples here: https://github.com/timlau/dnf-apiex Looks like now this modified code runs well today. Maybe today when I start the system, dnf got the full cache refresh when I did "dnf update" Tim, Thanks. I will check your samples. > dnf.exceptions.RepoError: Failed to synchronize cache for repo 'fedora':
> Cannot prepare internal mirrorlist: file repomd.xml was not found in metalink
commit 1ecf1de improves the exception error message so the real problem is easier to spot.
we still have to improve or document the releasever setting.

Thanks Ales. This http://akozumpl.github.io/dnf/api_conf.html#dnf.conf.Conf.substitutions helped me. |
