oh yes the non-free is all there i cliped it when I Pasted the list sorry

type "gksudo gedit /etc/apt/sources.list" in a terminal
remove the last line and save the file.

then paste this in a terminal:
sudo wget http://medibuntu.sos-sts.com/sources.list.d/dapper.list -O /etc/apt/sources.list.d/medibuntu.list

I will try this but to let you klnow I have tried this before with the wget and most of the time it will not work I had to save the key page the last time I did this and import it.

Ok i did this command here is the result what did this do so i can learn from this? I did do the apt-get update and it updated even medibuntu with no errors

main@PC3:~$ sudo wget http://medibuntu.sos-sts.com/sources.list.d/dapper.list -O /etc/apt/sources.list.d/medibuntu.list

You did nothing special. Sometimes, one of our mirrors fails (404 or 403 errors), and the only thing to do is waiting, or retrying and hopefully you'll hit a non-broken mirror. ;)

Oh, sorry! This is not your issue.

In the sources.list pasted in the 4th post, there was a missing "repo/" in the url:

deb http://medibuntu.sos-sts.com dapper free non-fre
deb-src http://medibuntu.sos-sts.com dapper free non-fre

should be

deb-src http://medibuntu.sos-sts.com/repo dapper free non-free
deb-src http://medibuntu.sos-sts.com/repo dapper free non-free

Anyway, the command you entered (sudo wget http://medibuntu.sos-sts.com/sources.list.d/dapper.list -O /etc/apt/sources.list.d/medibuntu.list) will download an extra sources.list file for medibuntu.

Thanks Hanusz leszek, that solved my question.
