Glad your back, even fleetingly.
My next problem is 'Software Sources'
When I go to Menu>System Tools> I get 2 menu options with System Resources.
When I choose the top one, I have to Authenticate, and I am taken to the 'Software Sources' screen as shown in stage 5 of the steps you showed me. The boxes on the Peppermint tab all ticked and the 'Other Software' tab has all the boxes ticked except the cdrom:[Peppermint etc. I click Close and it takes me back to the Desktop.
When I click on the second instance of Software Sources, I get a warning message that reads "Please run this this software with administrative rights. To do so run this program with kdesudo." When I do that I enter the Athenticate again and this time I get some sound from the speakers but no further information from the terminal
Where have I gone wrong. Is there life on Mars. I am still enjoying the step into Linux
