*Created by: GeorgeSalt* I'm running Linux Mint 17.3 (64-bit). When I attempt to update, Synaptic reports: > Conflicting distribution: http://downloads.iridiumbrowser.de trusty InRelease (expected trusty but got stable)Failed to fetch http://downloads.iridiumbrowser.de/ubuntu/dists/trusty/InRelease Unable to find expected entry 'main/binary-i386/Packages' in Release file (Wrong sources.list entry or malformed file) > Some index files failed to download. They have been ignored, or old ones used instead. I believe 'main/binary-i386/Packages' should be 'main/binary-amd64/Packages'
