Synchronization can fail for a number of reasons. To get more information about a connection problem, run this command:
export URLGRABBER_DEBUG=DEBUG spacewalk-repo-sync -c <channelname> <options> > /var/log/spacewalk-repo-sync-$(date +%F-%R).log 2>&1

- GPG Key Mismatch
Uyuni does not automatically trust third party GPG keys. If package synchronization fails, it could be because of an untrusted GPG key. You can find out if this is the case by opening
/var/log/rhn/reposyncand looking for an error like this:
['/usr/bin/spacewalk-repo-sync', '--channel', 'sle-12-sp1-ga-desktop- nvidia-driver-x86_64', '--type', 'yum', '--non-interactive'] RepoMDError: Cannot access repository. Maybe repository GPG keys are not imported
To resolve the problem, you need to import the GPG key to Uyuni. For more on importing GPG keys, see Signing Repository Metadata.
- Checksum Mismatch
If a checksum has failed, you might see an error like this in the
Repo Sync Errors: (50, u'checksums did not match 326a904c2fbd7a0e20033c87fc84ebba6b24d937 vs afd8c60d7908b2b0e2d95ad0b333920aea9892eb', 'Invalid information uploaded to the server') The package microcode_ctl-1.17-220.127.116.11.x86_64 which is referenced by patch microcode_ctl-8413 was not found in the database. This patch has been skipped.
You can resolve this error by running the synchronization from the command prompt with the
spacewalk-repo-sync --channel <channelname> -Y
This option verifies the repository data before the synchronization, rather than relying on locally cached checksums.
- Connection Timeout
If the download times out with the following error:
28, 'Operation too slow. Less than 1000 bytes/sec transferred the last 300 seconds
You can resolve this error by specifying
reposync_minrateconfiguration values in
/etc/rhn/rhn.conf. By default, when less than 1000 bytes per second are transferred in 300 secs, the download is aborted. You can adjust the number of bytes per second with
reposync_minrate, and the number of seconds to wait with
