[Pavel Mlčoch]

When purging wwwoffle dpkg exists with exit status 128:

pavka@ubuntu:~$ sudo dpkg --purge wwwoffle
(Reading database ... 510865 files and directories currently installed.)
Removing wwwoffle ...
Stopping HTTP cache proxy server: wwwoffled ok.
Purging configuration files for wwwoffle ...
/etc/wwwoffle directory removed, including contents

dpkg: error processing wwwoffle (--purge):
 subprocess post-removal script returned error exit status 128
Errors were encountered while processing:

pavka@ubuntu:~$

TO REPRODUCE:
- install wwwoffle
- purge wwwoffle (sudo apt-get purge wwwoffle)
- observe message "subprocess post-removal script returned error exit status 128"

A solution it's to find for the bug
The probleme is to return exit code in part on code why don't return error code.

The orinige file is : /var/lib/dpkg/info/wwwoffle.prerm

The error is located in line 11 and 13 :
11 invoke-rc.d wwwoffle stop || exit $?
13 /etc/init.d/wwwoffle stop || exit $?

The modified line for resolve the bugs is :
11 invoke-rc.d wwwoffle stop
13 /etc/init.d/wwwoffle stop

I'm to attach file solution in attachment
The new file could be copied is to /var/dpkg/info/ (sudo cp wwwoffle.prerm /var/lib/dpkg/info/wwwoffle.prerm)
and after type (sudo apt-get install -f) for the upgrade or (soduapt-get remove wwwoffle) for remove it.

Le bug semble être résolu.
Le problème c'est que une partie du code qui doit pas retourner d'erreur en retourne.

Le fichier original est : /var/lib/dpkg/info/wwwoffle.prerm

Les erreurs sont situés à la ligne 11 et 13 :
11 invoke-rc.d wwwoffle stop || exit $?
13 /etc/init.d/wwwoffle stop || exit $?

Les lignes modifiés pour la résolution des bugs sont :
11 invoke-rc.d wwwoffle stop
13 /etc/init.d/wwwoffle stop

Dans l'attache je vous le fichier modifé.
Le nouveau fichier doit être copié dans le répertoire /var/lib/dpkg/info (sudo cp wwwoffle.prerm /var/lib/dpkg/info/wwwoffle.prerm) et après tapez la command (sudo apt-get install -f) pour une mise à jour ou (sudo apt-get remove wwwoffle) pour supprimer le paquet.

I can confirm the issue. After install, before uninstall, /etc/wwwoffle/ does exist.

[timothée ruffenach (timruff)]

Yes but this error don't to stop the remove install package or upgrade or install.

Setting importance to low.
