When running DNFtrans, after reaching line 450 of the tracking part, an error report appears, even though it ran normally before.

I'm certain that this isn't a hardware issue because I've encountered the same problem on different computers.

Please post your run files and we will try to understand the issue.

I had the same issue and turned out the export options, afterwards it worked.
