Hi, I followed the new process, but it's still missing: https://qubes-os.discourse.group/t/building-qubes-iso-fedora-32-dnf-error-python2-sh-unable-to-find-match/667/18?u=qufo

I just build mgmt-salt. I changed in qubes-src/mgmt-salt/yaml-dumper the first line from
#!/usr/bin/python2 -O
to
#!/usr/bin/python -O

I try to build the ISO now.

Fixed with QubesOS/qubes-mgmt-salt@41dd4a6 and QubesOS/qubes-mgmt-salt@4290985
Downloading new sources (make get-sources) should be enough.
