spacewalk Error: Cannot retrieve repository metadata (repomd.xml) for repository

Created a new channel on spacewalk server and after using rhnpush to add the packages, client wasn’t able to download any packages and I kept getting following:

Error: Cannot retrieve repository metadata (repomd.xml) for repository: <channel name>

I tried making sure time was in sync. Tried yum clean all on client, no help.

Then on the spacewalk server in the channel details, this is what I saw:

Last Repo Build: none
Repo Cache Status: none

So it had not built the repo yet.

Searching on google, multiple other tries, I got the following hint:

/etc/init.d/taskomatic status
stopped.

taskomatic was not running on spacewalk server and hence repo was not built. starting the service fixed this in few minutes.

/etc/init.d/taskomatic start
