Comment 3 for bug 1609169

Ok. Weird.

I have three other PPA's - google-chrome-stable, avidemux and zabbix. Disabled all three and uninstalled the packages they provided + any dependencies. Then cleared my package lists from /var/lib/apt/lists and tried again. Same issue.

The following packages will be REMOVED:
  libmyth-0.28-0 libtag1-vanilla libtag1c2a mytharchive mythbrowser mythbuntu-bare-client
  mythbuntu-desktop mythgallery mythmusic mythnetvision mythnews mythtv mythtv-backend
  mythtv-backend-master mythtv-common mythtv-database mythtv-dbg mythtv-frontend
  mythtv-theme-mythbuntu mythtv-transcode-utils mythweather mythweb

Given the information you had given me I took the plunge and uninstalled all the mythtv packages and then installed kodi - which installed the libtag1v5 and libtag1v5-vanilla packages. During the uninstall I noticed something interesting.

Removing libtag1c2a:amd64 (1.9.1-2.2~ppa~trusty) ...
Removing libtag1-vanilla:amd64 (1.9.1-2.2~ppa~trusty) ...

So during the upgrade these had not been upgraded. Why I have no idea.

Once I had installed kodi I re-installed mythtv and had a working system again...

And then re-installed mythtv. The list of packages to install was:

The following NEW packages will be installed:
  hdhomerun-config-gui libaa1 libbasicusageenvironment1 libcddb2 libchromaprint0 libdirectfb-1.2-9
  libdvbpsi10 libexiv2-14 libfreerdp-cache1.1 libfreerdp-client1.1 libfreerdp-codec1.1

  libfreerdp-locale1.1 libfreerdp-primitives1.1 libfreerdp-utils1.1 libgles1-mesa libgles2-mesa

  libxml-treebuilder-perl mytharchive mythbrowser mythbuntu-bare-client mythbuntu-desktop

  mythtv-common mythtv-database mythtv-dbg mythtv-frontend mythtv-theme-mythbuntu
  mythtv-transcode-utils mythweather mythweb vlc vlc-nox vlc-plugin-samba

which looks to me like that although I had upgraded to 0.28 before doing the 16.04.1 upgrade something had caused certain packages to be held but not sure what or why.

Thanks for your help.
