Package: ack-grep
Version: 2.14-4
Severity: grave
Justification: renders package unusable
ack-grep fails to install pretending `/usr/bin/ack' is diverted by
`/usr/bin/ack-grep' although the /usr/bin/ack file does not exist:
$ apt-get install ack-grep
Reading package lists... Done
Building dependency tree

It works well after manullay removing the diversion:
$ dpkg-divert --list "*ack*"
local diversion of /usr/bin/ack-grep to /usr/bin/ack
$ dpkg-divert --remove /usr/bin/ack-grep
Removing 'local diversion of /usr/bin/ack-grep to /usr/bin/ack'
I do not understand why the diversion is still there: if I remember well,
the ack-grep package was installed on this system, then removed. The
installation of the package works well on a freshly bootstrapped debian sid.
Besides, I am not sure the diversion is still needed, since according to
apt-file, ack-grep is the only package providing /usr/bin/ack.
Thanks

Well, I consider that "somewhere" to be here in this bug report with
the explicit solution for the fix to be in
https://bugs.launchpad.net/ubuntu/+source/ack-grep/+bug/1385390/comments/3
Nevertheless thanks for the bug report and hence the trigger for
documenting this issue.

As any note inside the package that should still reach Jessie would
still require a freeze exception etc.pp. we think it's overkill to
update the package before the Jessie release just for some
documentation note.
And since this is an issue which only comes up at the Wheezy to Jessie
dist-upgrade (or the upgrades to Ubuntu 14.04 which already has been
released), fixing this after Jessie makes no more sense either.
So I'm herewith closing this bug report.
If anyone from the release team disagrees and would like to see a fix
for this in Jessie, I'm happy to provide one. But after a discussion
on #debian-perl, we are expecting that the release team will see the
situation probably as much as overkill as we do, given that only
systems with manual local changes are affected.
Regards, Axel
