This is because exaile was removed from Debian sid (see https://bugs.debian.org/813255 for rationale), and the removal propagated to xenial. The only reason why exaile is still installable in xenial is because gstreamer0.10 still happens to be available in xenial (it'll certainly be removed in Ubuntu at some point as well).
See https://github.com/exaile/exaile/wiki/PyGI-migration- tasklist-%28GTK3-GStreamer-1.x%29 for info about upstream's porting efforts to gstreamer 1.x. ** Bug watch added: Debian Bug tracker #813255 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=813255 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1575533 Title: Exaile package missing in Xenial To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/exaile/+bug/1575533/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
