[ubuntu-uk] apt-get update / apt-get upgrade question

[Anton Piatek]

Upgrade ignores some packages and dost-upgrade tries to do more.

Aptitude is often said to be better and supports safe-upgrade and
full-upgrade as the equivalents to the above apt-get commands. Aptitude is
said to have a better dependency resolution algorithm.
