How do I upgrade Scientific Linux 6.3 to 6.6

Question

I am upgrading Scientific Linux 6.3 to 6.6

I have to update machines of Scientific Linux 6.3 to 6.6. I tried #yum list updates and .# yum update

It downloaded some files and installed. But my Scientific Linux is still showing Scientific Linux 6.3.

.#yum list updates returns "Loaded plugins: refresh-packagekit,security".

Doing the same worked fine in Red Hat Linux.

Solution 1

Install yum-cond-sl6x if it not available from

http://rpm.pbone.net/index.php3?stat=3&search=yum-conf-sl6x&srodzaj=3

follow rpm -ivh

.#yum clean all

.#yum update

Solution 2

For doing and update between point releases (e.g. 6.3 to 6.6) you simply have to run.

yum install yum-conf-sl6x

This is also documented in in the Scientific Linux FAQ

It does not not work if you want to Upgrade from one major (e.g. 6 to 7) version to another.

Solution 3

Make sure that the sl6x repo is enabled. Else 'yum update' will return nothing. You can enable it on demand with:

# yum --enablerepo=sl6x update

You can always just use a disk to update your installation.

@Ramhound This is not correct in the current situation. One can not upgrade between major version but they can within minor releases. See my answer for more info.

Yes, I have already tried doing this and its still the same :(

This is what I was missing. Without this repo the yum-conf-sl6x package was reported as already installed, but didn't update anything.
