yum update repository error in centos 7

[LouisChego]

Hi,

I have a VPS server and when I try to update the repository with the following command ( yum update -y ) it returns me with the following error:

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.

I was wondering if someone could help me.

Try to run this command first:

yum clean all

Later:

yum update -y

If you previously have added additionalpository to your system, it is likely causing the failure. Try disabling additional repositories by editing their file located in /etc/yum.repos.d/ by changing enabled=1 to enabled=0. Then try yum update -y again.

Hi,

I have seen this issue solved by replacing the nameservers on the /etc/resolv.conf file.

Change it to something like 4.2.2.2 or 8.8..8.8 and this helps solve the issue

Regards.

Are you using SSH or VNC to access the server operating system?

Have tried using simply using yum update help.
