thanks david for the help the server is back on now but when i run apt-get update i still get a error
Unable to fetch file, server said 'Can't open /debian-marillat/dists/sid/main/binary-i386/Packages.gz: No such file or directory ' [IP: 188.8.131.52 21]
Reading package lists... Done
The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 7D8C40224F83C751
W: You may want to run apt-get update to correct these problems
E: Some index files failed to download, they have been ignored, or old ones used instead.
i looked in the forum and saw it maybe had something to do with the sources.list but i can`t find it !
