Ubuntu has released 12.04.2 LTS, which has a newer kernel than the one that comes with 12.04.1 LTS.
I prefer to keep server and clients with the same kernel version. Can this be done?
It's pretty simple, actually. Just run...
sudo apt-get install linux-generic-lts-quantal xserver-xorg-lts-quantal
and both kernel and X stack will be upgraded.
Note: this upgrade worked fine on a simple HTPC running Mythbuntu, but on a older client that had been originally a 10.4 system, it was severly broken. Might be a good idea to back-up your system before trying this.
It didn`t take very long for me but I have high speed internet service.
Thanks to chaskes for the explanation.
