Here I sit and wonder why the packages-database appears to be damaged after I manually added a repository.
Here' s what I did:
1 clicked 'view/manage repositories' ; in the lower end of the next window is space to enter a url;
2 entered the url of the desired repository: http://packages.ubuntu.com
3 clicked 'add', clicked 'apply'; clicked 'close'
4 closed the program
5 started adept again and got the message that the database was damaged, I should try apt-setup or something.
Because I was not able to repair the packages-database because apt was not yet installed, I decided to install kubuntu again.
Then I started adept and repeated steps 1 to 4, with one difference: in step 2 added /dapper/ to the url. The same difficulties with the packages-database occured...
The online adept-handbook does not give any details about manually adding a new repository, but only how to activate the listed ones.
A month ago I installed the 32-bit version of dapper and I was able to manually add a repository.
Did more people run into this difficulty, or did I do something wrong?
