Bug#531611: gnome-session: postinst fails when calling update-alternatives

[Wolf Wiegand]

Package: gnome-session
Version: 2.26.1-6
Severity: normal

Hi,

(maybe this should have a higher severity, but I'm not sure whether this
is caused by a wrong configuration on my side)

after the upgrade from 2.22.3-3 to 2.26.1-6, the postinst fails with the
following error:

Setting up gnome-session (2.26.1-6) ...
Installing new version of config file /etc/gnome/defaults.list ...
update-alternatives: error: alternative x-session-manager.1.gz can't be slave of
 x-session-manager: it is a master alternative.
dpkg: error processing gnome-session (--configure):
 subprocess installed post-installation script returned error exit status 2


My x-session-alternative:

$ ls -al /etc/alternatives/x-session-*
lrwxrwxrwx 1 root root 22 Jun  2 20:08 /etc/alternatives/x-session-manager -> /usr/bin/icewm-session


Running the postinst with -x results in the following:

:~ $ sudo /var/lib/dpkg/info/gnome-session.postinst configure
+ set -e
+ [ configure = configure ]
+ update-alternatives --install /usr/bin/x-session-manager x-session-manager /usr/bin/gnome-session 50 --slave /usr/share/man/man1/x-session-manager.1.gz x-session-manager.1.gz /usr/share/man/man1/gnome-session.1.gz
update-alternatives: error: alternative x-session-manager.1.gz can't be slave of x-session-manager: it is a master alternative.


Cheers,

Wolf
