Issues with mock and dnf on rawhide/F40 - packaging - Fedora mailing-lists

15 Feb 2024


      Hi,
  while testing building some packages on rawhide, using mock --rebuild, I got 
into trouble with the following error:
$ mock -r fedora-40-x86_64 --rebuild pygsl-2.3.4-1.fc41.src.rpm
Start: installing minimal buildroot with dnf5
execv(/usr/bin/dnf5) failed: No such file or directory

This happened last week from F39 and now also with F40.
The only option for me was to add --config-opts='package_manager=dnf' to the 
call.
How can I fix that? Either to use dnf4 or dnf5 without further changes?
Are there any configuration files that are changed on my installation?
Best regards,
