RHEL 7 yum update is not working

Latest response

Good Afternoon,

I am attempting to run a yum update but it keeps failing with the following output:

One of the configured repositories failed (Unknown) , 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.

    1. 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).

    2. Run the command with the repository temporarily disabled
      yum --disablerepo= ...

    3. 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 <repoid>

      subscription-manager repos --disable=

    4. 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

      yum-config-manager --save --setopt=<repoid>.skip_if_unavailable=true

Insufficient space in download directory /var/cache/yum/x86_64/7Server/rhel-7-server-rpms
* free 0
* needed 59 M

I deleted everything in that folder and run:

rm -rf /var/cache/yum/*
yum clean all
yum update

I am still getting that same error.



Typically, this happens when the /var partition fills up very rapidly. Sometimes there is a "runaway" process that fills up /var/log and prevents /var/cache from having room. There are a couple of commands you can use to check.

# df -hP

the "P" just gives it a better format that I like. This will tell you how much room you have in each partition and if you have one big partition or how it is divided.

If you have you a /var partition, you can see what folder is using the most space with the following command:

# du -sh /var/* |sort -h

This will compute the space for each folder under /var and sort it by size. You can then take steps to either reduce space in the /var partition (if /var has its own partition), or expand the partition if you have LVM and have room to expand it.

Hope this helps,
