package courier-base 0.61.2-1ubuntu1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 2

[Mark A. Hershberger]

As per subject... from a synaptic upgrade on karmic today.

ProblemType: Package
Architecture: amd64
Date: Thu Aug 13 15:24:45 2009
DistroRelease: Ubuntu 9.10
ErrorMessage: subprocess installed post-installation script returned error exit status 2
Package: courier-base 0.61.2-1ubuntu1
ProcVersionSignature: Ubuntu 2.6.31-5.24-generic
SourcePackage: courier
Title: package courier-base 0.61.2-1ubuntu1 failed to install/upgrade: subprocess installed post-installation script returned error exit status 2
Uname: Linux 2.6.31-5-generic x86_64

[Mark A. Hershberger (hexmode)]

key bit:

update-alternatives: error: alternative link /usr/share/man/man5/maildir.5.gz is already managed by maildir.5.gz.

dpkg: error processing courier-base (--configure):

 subprocess installed post-installation script returned error exit status 2

So... the manpage link should be fixed or a conflict added or ... ?

[Mark A. Hershberger (hexmode)]

Specifically, maildrop define maildir.5.gz as the alternative and courier-base wants maildir.5. Confusion reigns!

Patch attached.

Can't reproduce it, i just did:
- Create a jaunty chroot
- install courier-base
- sed -e 's/jaunty/karmic/g' /etc/apt/sources.list
- apt-get update; apt-get install courier

The upgrade runned fine. No complains from apt.

[Scott Kitterman (kitterman)]

You need to install maildrop first.

[Darik Horn (dajhorn)]

Note that there are two maildrop providers in Karmic:

  * http://packages.ubuntu.com/karmic/maildrop
  * http://packages.ubuntu.com/karmic/courier-maildrop

This glitch happens only with the non-courier maildrop package. Any easy fix for me was:

  $ apt-get remove maildrop
  $ apt-get install courier-maildrop

Downgrading to the Jaunty package also works.

[John Dong (jdong)]

ACK from motu-sru for the diff attached.

[Scott Kitterman (kitterman)]

Accepted into karmic-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!

[Scott Kitterman (kitterman)]

Why did you change this from fix committed?

[Martin Pitt (pitti)]

Any testers?

All packages installed without error.

I think someone else may need to double check as I'm not sure I configured everything correctly as I have not setup a mail server before. The best tutorial I could find was slightly modifying the instructions at http://www.howtoforge.org/perfect-server-ubuntu-9.10-ispconfig-3-p4 to test this package.

[Martin Pitt (pitti)]

Thank you for testing! Since the change only affect the packaging, not the actual upstream code, this looks sufficient.
