Solution: $ sudo delgroup scanner $ sudo apt-get install colord Details: I'm seeing the same problem after upgrading to 12.04. There is no helpful output from the post install script (/var/lib/dpkg/info/colord.postinst) even if you run it manually. Taking a look inside, the first command is:
addgroup --quiet --system scanner which fails with no output (thanks to --quiet). Running without --quiet gives: $ sudo addgroup --system scanner addgroup: The group `scanner' already exists and is not a system group. Exiting. So there's the problem: the group is already there but is not a system group. Taking a look at the group I see: $ grep scanner /etc/group scanner:x:1001:colord Indeed it is not a system group, and it only seems to be used by colord. So I took the liberty of removing it: $ sudo delgroup scanner Removing group `scanner' ... Done. Then reinstalling colord: $ sudo apt-get install colord Reading package lists... Done Building dependency tree Reading state information... Done colord is already the newest version. 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded. 1 not fully installed or removed. After this operation, 0 B of additional disk space will be used. Do you want to continue [Y/n]? Setting up colord (0.1.16-2) ... $ And viola, the problem is solved. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/989921 Title: package colord 0.1.16-2 failed to install/upgrade: ErrorMessage: subprocess installed post-installation script returned error exit status 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/colord/+bug/989921/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
