Unable to check update due to a system error: Error running a command. cmd

Perhaps that’s due to the disjoint way Rockstor uses yum (like many automated update solutions). The actual update of the caches is handled by yum-cron, which is run hourly and daily. Although I haven’t looked at the Rockstor source which handles the updates, I would guess that it runs “yum -C check-update” to check for updates and “yum -C update” to install them. That -C forces yum to run from the local caches, without querying any repos, so no hang-up on failed remotes.

To bring this topic up again.
I’m running into this problem again. Internet access is fine. Did a “yum clean all && yum update”, but all i get is

[root@rockstor-nas ~]# yum clean all && yum update

One of the configured repositories failed (Subscription channel for testing updates),
and yum doesn’t have enough cached data to continue. At this point the only
safe thing yum can do is fail. There are a few ways to work “fix” this:

 1. Contact the upstream for the repository and get them to fix the problem.
 2. Reconfigure the baseurl/etc. for the repository, to point to a working
    upstream. This is most often useful if you are using a newer
    distribution release than is supported by the repository (and the
    packages for the previous distribution release still work).
 3. Run the command with the repository temporarily disabled
        yum --disablerepo=Rockstor-Testing ...
 4. Disable the repository permanently, so yum won't use it by default. Yum
    will then just ignore the repository until you permanently enable it
    again or use --enablerepo for temporary usage:
        yum-config-manager --disable Rockstor-Testing
    or
        subscription-manager repos --disable=Rockstor-Testing
 5. Configure the failing repository to be skipped, if it is unavailable.
    Note that yum will try to contact the repo. when it runs most commands,
    so will have to try and fail each time (and thus. yum will be be much
    slower). If it is a very temporary problem though, this is often a nice
    compromise:
        yum-config-manager --save --setopt=Rockstor-Testing.skip_if_unavailable=true
