libapache2-mod-python failed to purge

[David]

Binary package hint: libapache2-mod-python

I installed libapache2-mod-python. Then I removed it via synaptic, but forgot to completely remove it. So I then found the package and selected the "Mark for complete removal" option. Upon clicking apply, it pops up saying an error occurred." E: libapache2-mod-python: subprocess installed post-removal script returned error exit status 1"

== DESCRIPTION ==
When purging the package libapache2-mod-python.postrm is run twice, each time executing "a2dismod python". The script should only disable the module when called with the 'remove' argument.

== VERSION ==
libapache2-mod-python | 3.3.1-8build1 | karmic-updates | source, amd64, i386
libapache2-mod-python | 3.3.1-8build1 | lucid | source, amd64, i386

== HOW TO REPRODUCE ==
# apt-get install libapache2-mod-python
# dpkg --purge libapache2-mod-python

Not a synaptic issue but a packaging issue in libapache2-mod-python. Closing synaptic task.

[Jean-Baptiste Lallement (jibel)]

Confirmed in karmic & lucid (3.3.1-8build1)

[Jean-Baptiste Lallement (jibel)]

Patch against lucid + SRU

* Only disable apache module when postrm is called with the remove argument to avoid to disable it twice.
* Tolerates a failure of a2dismod.

I have unsubscribed ubuntu-universe-sponsors. The package is in main. Therefore I subscribe ubuntu-main-sponsors.

Thanks Jean-Baptiste for the patch. I've uploaded a version based on the debian patch proposal (which is quite similar to the debdiff posted here).

This bug was fixed in the package libapache2-mod-python - 3.3.1-8ubuntu1

---------------
libapache2-mod-python (3.3.1-8ubuntu1) lucid; urgency=low

  * debian/libapache2-mod-python.postrm: Don't fail if the module has already
    been disabled. (LP: #500390)
