Scientific Linux 6 : How to upgrade to the latest SL 6.x

SL 6.1 has been released on July 28th , 2011.

Here’s an explanation of how to upgrade from SL 6.0 to SL 6.1.

# cat /etc/redhat-release Scientific Linux release 6.0 (Carbon) # yum --releasever=6.1 update –y

man yum

--releasever=version              Pretend the current release version is the given string. This is              very useful when combined with --installroot. Note that with the              default  upstream cachedir, of /var/cache/yum, using this option              will corrupt your cache (and you can  use  $releasever  in  your              cachedir configuration to stop this).

# ls /var/cache/yum/x86_64/6.* /var/cache/yum/x86_64/6.0: sl  sl-security /var/cache/yum/x86_64/6.1: sl  sl-security

# cat /etc/redhat-release Scientific Linux release 6.1 (Carbon) # uname -r 2.6.32-131.6.1.el6.x86_64
