I retried the dnf update operation and it completed successfully then. Steps to Reproduce: 1. dnf update 2. have bad luck with stale metadata or stale mirrors (?) 3. Actual results: Traceback encountered. Expected results: No tracebacks. At worst a human readable error is printed. Though I'm not sure why I'm having so many 404 errors in the first place. Maybe that's a bug of its own. Additional info: I'm attaching the complete terminal output.
Michael, I will look at this, thanks for reporting.
In my case it happened just before dnf started to download packages. The next try succeeded without any problems. Is this ok [y/N]: y Downloading Packages: Traceback (most recent call last): <same traceback as in comment #0>
Moving to Tim who got a patch. Tim, I merged your fix as 87a0b0a, thank you!
