I have recently upgraded my desktop OS from Ubuntu 12.04 to 12.10 (complete re-install). Before the switch I made a list of all programs installed on my Ubuntu 12.04.
sudo dpkg --get-selections > file
After that I re-installed Ubuntu 12.10 and when all was done I performed the following command:
sudo dpkg --set-selections < file sudo apt-get dselect-upgrade
Here is when the problems start: I get several warnings like this when performing the commands above:
dpkg: warning: package not in database at line xxx
and many of the programs are not installed. I don't know what the line means.
I have searched the web, and it seems that I'm not the only one suffering from this. I have not find any solution that worked for me.
Any ideas what is causing this?
