That's quite an old package, I don't see it in the supported releases: http://packages.debian.org/libmtp5 Can you explain how did this happen? I can only assume that you upgraded, but from which older release to which one, using which commands? :)
Also, reply with the output of: apt-cache policy libmtp5 libmtp7 libmtp8 -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe". Trouble? Contact listmas...@lists.debian.org
