** Description changed:
- No idea. The installation was going on and suddenly this message
- appears.
+ [Impact]
+ Upgrades from 11.10 to 12.04 fail indicating "exit status 1" from
installing/upgrading colord.
+
+ [Discussion]
+ /var/lib/dpkg/info/colord.postinst does not produce helpful error messages
even if run manually. But the script is trying to run this command:
+
+ addgroup --quiet --system scanner
+
+ Running it without the --quiet option reveals the error:
+
+ 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.
+
+ [Test Case]
+ 1. Install Ubuntu 11.10
+ 2. ???
+ 3. Upgrade to Ubuntu 12.04
+
+ Expected: Successful upgrade with no errors
+ Actual: Upgrade hits this error - "package colord 0.1.16-2 failed to
install/upgrade: ErrorMessage: subprocess installed post-installation script
returned error exit status 1"
+
+ [Workaround]
+ sudo delgroup scanner
+ sudo apt-get install -f
+
+ [Original Report]
+ No idea. The installation was going on and suddenly this message appears.
