yum update on CentOS 7 error

[Knath]

I have a CentOS 7 server that needs to be updated, but I keep getting errors when trying to update.
I tried running the suggested “yum –enablerepo=artica_pandorafms clean metadata” but it still fails ?

How can I fix this problem so I can update ?
Thank you in advance.

That's not a CentOS repo. I would just disable it for now - temporarily by adding --disablerepo=artica_pandorafms to your yum command or permanently by editing the /etc/yum.repos.d/ .repo file that is for that repo and changing enabled=1 to 0 and saving it.
