#4548 Diagnostics from `dnf builddep` not shown
Opened by yannd. Modified

Close Issue

We have builds, on a being-configured alma10 environment, where installation of a package's builddeps actually triggers removal of rpm-build... which does not end well.

Example: https://koji.xcp-ng.org/kojifiles/work/tasks/490/100490/root.log
I actually attempted to add more verbosity flags in there but that did not help:

If we try to run dnf builddeps in an Alma10 container using thednf.conf used by mock, however we can see:

(try to add '--skip-broken' to skip uninstallable packages)

This error is crucial to solving the problem, yet we cannot seem to get it from koji's logs: stderr data would be lost in this case?
