Cannot upgrade Scientific Linux to version 6.5

Question

I have been trying to figure out a way to get my Scientific Linux box to upgrade to version 6.5. It's currently 6.4 and everytime I perform a yum update I get an error message (see below!). Can anyone tell me what needs to be done to get past this issue?

Some Stats:

• Scientific Linux 32 bit - running on Lenovo Thinkpad 430 4GB RAM - 320GB HDD
• No extras or addons at all, just plain install via CD/DVD which was done from around Nov. 2012

error message:

Answer 1

As of right now, December 6th, 2013, 16:00 UTC, Scientific Linux hasn't released version 6.5. Redhat, CentOS and Oracle have released their 6.5 updates, but SL has not. Historically I'm under the impression they take a bit longer than CentOS and Oracle to vet the RHEL changes and port them over to their release.

@SuperMagic's answer looks to be the correct one but I'll offer this tip for situations such as the one you're encountering.

When you get these messages when running yum update:

http://dl.atrpms.net/src/el6.4-i386/atrpms/stable/repodata/repomd.xml: [Errno 14] PYCURL ERROR 22 - "The requested URL returned error: 404 Not Found"
Error: Cannot retrieve repository metadata (repomd.xml) for repository: atrpms-source. Please verify its path and try again

The messages is pretty clearly telling you that the URL "http://dl.atrpms.net/src/el6.4-i386/atrpms/stable/repodata/repomd.xml" is 404. Additionally the repository "atrpms-source" isn't accessible.

You could disable that one repo prior to running the update like so:

$ yum update --disablerepo=atrpms-source
