Thank you evo2.
I am sorry but I really am having a struggle. Went to the wiki page, and felt a bit lost. Tried to paste the first line of instruction to \etc\apt\sources.list .
"# Backported packages for Debian Lenny
lenny-backports main contrib non-free"
Got error message that I did not have permission or there was an error in the info inserted. Well, moved the #part of the instruction to between the # signs at the top, tried to save again - same error message.
Well, OK let's really show how little I know - I then tried to sign in as root, and get the message that system administrator is not permitted to sign in at this screen. Umm, hair loss is not solving this one. I need to find out how and where to sign in as root, so I can (I assume) get on with the rest of the exercise.
If you aren't too frustrated by my complete lack of knowledge I would appreciate assistance. Shall look into the OS forums for clues, and will check the "help" files.
First things first seems to be the order of what to do.
Thanks again for your interest and your help so far
ps. Found the root login secret - had to set a permission to allow login ... just knew it had to be something simple. Will now have a crack at the next task - \sources.list
