16.04 libtag dependancy issues

[Dale]

This issue has come up from trying to install Mixxx from their official LaunchPad host ppa and it appears to reference libtag1-vanilla, which does appear to exist in 16.04 but I believe should be superseded by libtag1v5-vanilla, yet it doesn't seem to recognise as such. As it then can't be manually installed or the other removed I think there is a deeper issue with this package than just Mixxx having the wrong one down as a dependency.

This has been reported to the Mixxx developers on their forum about a week ago but no official response as yet...

I've run this in a virtual box but there are multiple users who have reported this on their main systems (at least four I've seen.)

Ahhh obviously fully Mixxx's fault, just realised the libtag version it fails to downgrade to is in their ppa and not the Ubuntu repo looking at the apt-cache policy output.

Why does Launchpad not recognise Launchpad's bug tracker when you try and associate another package as being affected? I wanted to correctly link this bug on the Mixxx tracker but it throws up an error of unrecognise bug tracker!!

As this bug is obviously from mixxx PPA's side and mixxx has closed their bug report, closing this bug report as well and marking as "fix released".

If you have any similar issue on a supported Ubuntu system, please submit a new bug report instead.
