If you’re one of us who has their CentOS 7 cloud servers hosted on Rackspace then you’ll probably encounter this notorious error when updating your Plesk release.

Yum update errno 14 http error 404: not found – CentOS

{Okay – I know a lot of hardcore sys admins frown upon Plesk usage but I have been using it since 2003 and it has been very reliable and very convenient for me – a non-Linux geek. Using Plesk for 16 years so far and I swear by this product. }

For non-experts if you encounter the above error message while trying to update Plesk and you try to search for it on Google , it’s gonna give you a lot of other results. This simple one worked for me — disable the IUS repos because Rackspace’s repo mirror config isn’t working well:

yum-config-manager –disable ius
