Update problems in Natty
Due to heavy rains my connection slowed down. Did this : Software sources--Ubuntu Software--Download from other--select best server. Tests done, server selected, reloaded.
The Problem : Update manager shows the same list of applications I have already installed / updated from my previous server.
It does not make any sense to reinstall all the applications just because I chose a different server.
This tells that Natty or perhaps all Ubuntu distros do not have or make a list of installed applications and their versions.
This is not the sign of a good Operating System.
Do this and post your experiences here.
