Hi, This is my first time using Knoppix, do anyone know why i am getting these errors when i running Update Manager program? W: Failed to fetch http://ftp.c.debian.org/debian/dists...ze/Release.gpg Could not resolve 'ftp.c.debian.org' W: Failed to fetch http://ftp.c.debian.org/debian/dists...slation-de.bz2 Could not resolve 'ftp.c.debian.org' W: Failed to fetch http://ftp.c.debian.org/debian/dists...slation-en.bz2 Could not resolve 'ftp.c.debian.org' W: Some index files failed to download, they have been ignored, or old ones used instead. Thanks
