Package: apt
Version: 1.4.8
Severity: minor
Over in https://bugs.debian.org/909000,
bug in apt -- the reason apt won't let you install enigmail is because
the version of thunderbird in debian-security stretch/updates
(thunderbird 1:60.0) is marked with:
Breaks: enigmail (<< 2:2~)
That's correct, because versions of enigmail prior to 2.0 do not work on
thunderbird 60 any longer.
it would be nice if apt improved the reporting here, to identify that
the cause of the problem is a conflict between the currently installed
version of thunderbird, and the desired version of enigmail.
Compare the differences with neither thunderbird nor enigmail installed:
