Title: package libanyevent-perl (not installed) failed to install/upgrade: trying to overwrite '/usr/share/man/man3/AnyEvent.3pm.gz', which is also in package anyevent-perl 0:1.02-0.2

TEST CASE:
1. Add karmic to /etc/apt/sources.list.
2. Make sure libanyevent-perl is not installed.
3. Install anyevent-perl (from karmic, not available in lucid).
4. Install libanyevent-perl.

With 5.240-1 installation will fail (trying to overwrite files from
anyevent-perl). With the patch applied, dpkg should remove
anyevent-perl in favor of libanyevent-perl.

libanyevent-perl in Lucid should Conflict, Replace and Provide
anyevent-perl (which has been removed).

Even if libanyevent-perl in maverick does not do so in order to not
deviate from Debian, this should catch most people upgrading from
Karmic. The edge-case is people having anyevent-perl installed in
Karmic, upgrading to Lucid without installing libanyevent-perl and then
upgrading the Maverick.

A (untested) patch to add Conflicts, Replaces and Provides to d/control
is attached.

It seems the correct version number would be 5.240-1ubuntu0.1. Updated
patch is attached.

TEST CASE:
1. Add karmic to /etc/apt/sources.list.
2. Make sure libanyevent-perl is not installed.
3. Install anyevent-perl (from karmic, not available in lucid).
4. Install libanyevent-perl.

anyevent-perl in favor of libanyevent-perl.

Thanks for working on that!

Before uploading to -proposed, I ran update-maintainer to update the maintainer field. Please remember to do so next time ;-)
I also deleted the Provides clause in debian/control as the only dependency of anyevent-perl has been updated and libanyevent-perl will be always installed in a normal installation. No need to declare anyevent-perl as virtual package.

Waiting for ubuntu-sru team member to approve the upload.

Thanks again!

Accepted libanyevent-perl into lucid-proposed, the package will build now and be available in a few hours. Please test and give feedback here. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you in advance!

I have reproduced the upgrade issue with the version of libanyevent-perl in lucid, 5.240-1, and can confirm that the version in lucid-proposed, 5.240-1ubuntu0.1, is installable when the package anyevent-perl from karmic is already installed. I tried to test out the benchmarking scripts included in the package's examples/ directory, but the import paths were not set up to work correctly out of the box.
It would be ideal if someone who makes use of the libanyevent-perl package could confirm that the version in proposed does not introduce any regressions. Thanks!

This is an upgrade-only problem, invalidating maverick task.

[Launchpad Janitor (janitor)]

This bug was fixed in the package libanyevent-perl - 5.240-1ubuntu0.1

  * debian/control: Replace and Conflict on anyevent-perl to avoid an error when
    upgrading from previous versions. (LP: #572151)
