We ran into some minor issues trying to load packages into a custom child channel. First, rhnpush wouldn't recognize deb packages. This minor change allowed rhnpush to recognize .deb files diff -u /usr/lib/python3.6/site-packages/rhnpush/uploadLib.py.bak /usr/lib/python3.6/site-packages/rhnpush/uploadLib.py --- /usr/lib/python3.6/site-packages/rhnpush/uploadLib.py.bak 2022-04-13 11:02:58.598147587 -0700 +++ /usr/lib/python3.6/site-packages/rhnpush/uploadLib.py 2022-04-13 10:07:14.590320048 -0700 @@ -177,7 +177,7 @@ for filename in listdir(self.options.dir): # only add packages - if filename[-3:] in ("rpm", "mpm"): + if filename[-3:] in ("rpm", "mpm", "deb"): self.files.append(filename) def filter_excludes(self): Next, we ran into some permission issues on the back end.

Chown wwwrun.www /var/spacewalk/packages/1/stage to match the other dirs in /var/spacewalk/packages/1 allowed the rhnpush to succeed. Cheers, Paul-Andre Panon
