I'm using Linux Mint 16 KDE Petra.
I've been getting this message for about a few weeks now, every time there is an update available throught the update manager.
W: Failed to fetch http://packages.domain.com/dists/saucy/InRelease
W: Failed to fetch http://packages.domain.com/dists/saucy/Release.gpg Could not resolve 'packages.domain.com'
W: Some index files failed to download. They have been ignored, or old ones used instead.
Is there any way to fix this so this doesn't show
