I am new and do not, of course, know a lot about installing and maintaining an Ubuntu release.
One of the "tricks" I have learned to use is
sudo apt-get update followed by
sudo apt-get upgrade to download and install updates for the installed software.
I recently installed beta 2 of Ubuntu 12.04 (precise pangolin ?) to a test disk/partition just to see what it was like. After the install I updated the software using the commands I listed above because, well, that is what I always do.
Was this a mistake? Are the alpha & beta releases of Ubuntu updated in a different way?
I recently saw reference to the
dist-upgrade command for
apt-get and decided I would try using that to update 12.04. A lot of programs were upgraded, including the kernel so I'm wondering if using just
sudo apt-get upgrade was the wrong way to go for a release which is still under development.
