can you paste the contents of the file...
Everything relies on the version of gcc and glibc.
Those 2 files/packages put a limit on what version you can install.
That can only work if you have successfully downloaded the hdlists with urpmi.addmedia
sorry, that's not quite right...
"Configure Media Sources" is the gui for urpmi.addmedia
It should work.
lsb = linux standard base, If you go this way it could be more complicated.
Your system is quite old, I have forgotten too much about it.
Try to cut the name a bit. Like
Then "use the tab key to auto complete" the name (from the repo) from the konsole(cli).
Here is the name from the repo you named before.
Sometimes it want the full name, not just the first bit, but the version too.
It's fussy (temperamental).
