Try opening the Software Sources application and then under Offical Repositories click on Restore the default settings and then on Update Cache.

Excellent! It worked.
On Software Sources application I had previously clicked on: "Fix MergeList problems", etc, etc, on the Maintenance tab but it did not do anything. With your help it worked this time. Thank you.

Re: How can I reinstall essential packages?
Something else I'd like to ask if you can help.
On Home folder I have lots of stuff (especially when I show Hidden Files) which remained there each I was trying an application. How can I know which ones I can keep and which ones I can delete. And then how can I delete/remove them properly?

Re: How can I reinstall essential packages?
Hi,
I wouldn't worry about them. The hidden files and folders in home are normally config or user specific data / cache files for your applications. You will occasionally end up with 'orphan' files in here but they do no harm and in general will take up very little disk-space. If you do spot something that from it's name you are sure relates to an app you have installed and emoved just delete the files/folders in the normal way. If you are not sure what something is for just leave it alone.
