Red Hat not booting GUI and insufficient space

Good Morning,

When I boot up Red Hat all I see is a black screen and the GUI is not loading. I can log into the cmd line using alt +f3, and I resolved this issue before by running the cmd "yum reinstall telepathy-glib"

but when I try and run that cmd now I get:
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
2. Reconfigure the baseurl/etc. for the repository, to point to a working upstream. This is most often useful if you are using a new distribution release than is supported by the repository (and the packages for t he previous distribution release still work).

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

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
   or
   subscription-manager repos --disable =

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 much slower). If it is a very temporary problem though, this is often a nice compromise:
   yum-config-manager --save --setopt=.skip_if_unavailable=true

Insufficient space in download directory /var/cache/yum/x86_64/7Server/rhel-7-server-rpms
*free 0
*needed 100k

I have run the cmd: yum clean all

but it still does not work and I get the same error.

I thought maybe I needed some updates so I ran a yum update but that fails with insufficient space requirements as well, pointing to the same directory. Any assistance would be greatly appreciated.
