Just a quick hint this time. The Ubuntu package manager really simplifies life a lot in adding, removing and upgrading programs and satisfying their dependencies. It is really easy to add a new software or to ann a new repository. But not all the times that we installa a software and then remove it the Ubuntu package manager cleans up everything. Sometimes there are some packages containing shared libraries thata are not automatically de-installed since they might be used by other software.
Removing these packages is not so complicated. It is just a matter of entering the following line from the konsole: > sudo apt-get autoremove
After having typed the right password, apt scans all its list of installed software, looking for packages that can be removed. At the end it will give you the list of packages that are no longer used, and it will also inform you on how much disk space it will be freed. I suggest you to use after having installed a new version of the kernel. As always, here follows some links suggested by Google. Have fun with Ubuntu.
