The problem is addgroup --quiet --system scanner
That line exits with code 1, and the postinstall script has a 'set -e' which means abort on any error. If you already have the group 'scanner' (previous colord, or other scanning software) colord will fail to install or upgrade. Add a '|| true'. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/896503 Title: package colord 0.1.12-1ubuntu2 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/896503/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
