I have faced some problems with this feature (software). First of all it seems that I don't know how to use it. When I tried to update some packages I did : 1-Define Sources 1.1-New 1.1.1-Type of source = security updates 1.1.2-New source's name = XYZ 1.1.3-Select mirror (but before I update the mirror list) 1.1.4-Pressed <OK> 1.2-Pressed <OK> (to confirm the new source selected) 2-Reload Lists (*) (*) At this point my troubles began Tracking the troubles ..... Into the "Define Sources" windows already exists 2 entries : CD-1 Instalation..... and CD-2 bla-foo-bla..... Both of them were already marked. After adding the new source (mirror) it becames marked too. FIRST PROBLEM : When I call "Reload Lists" function the application only re-reads the CDs sources It never reads from the URL (new added source - mirror) that I have pointed. By this reason I delete both CD's entries and the feature worked fine. Where the CD1 and CD2 lists were persisted in the HD ? How can I rebuild the "Source Lists" using CD1 and CD2 lists ? SECOND PROBLEM : What can I do to keep a multi-list (CD1 + CD2 + URL1 +URL2...) filled and persisted ? I only need to choose one of them to "Reload" a List of Packages to update. I believe it is enough. The "software manager" don't runs like this. TIA Marcos Nobre.
