    Thanks for the instructions. I just upgraded a fresh CentOS 5.3 install up to CentOS 5.5 final. I followed your instructions exactly and they worked perfectly.

    I had been using Fedora before (way back on Fedora 7). I tried to upgrade through a few Fedora versions, but I decided it was time for the nightmare to end. It’s almost a shock that the same company that makes Fedora is really behind CentOS (Fedora = Beta, Redhat=Paid, CentOS=Free Redhat Clone w/out Support).

    Anyway, thanks for the post. It worked like a charm.

    [root@vel ~]# lsb_release -a
    -bash: lsb_release: command not found

    What should I do to this?

    Hi,

    Just done an upgrade from 5.3 to 5.4 using the above process (thanks! )

    It won’t upgrade any further than 5.4. How do I get it to go to 5.5 or above? I’ve tried yum clean all, and repeating the above process, but it just says nothing to upgrade.

    Cheers,

    Darren.
