Thank you for taking the time to file a bug report. Looks like it failed when the docker group already existed. I think the upgrade should still complete, however maybe there should be better logic in the postinst to check for the group first.
Since there is not enough information in your report to begin triage or to differentiate between a local configuration problem and a bug in Ubuntu, I am marking this bug as "Incomplete". We would be grateful if you would: provide a more complete description of the problem, explain why you believe this is a bug in Ubuntu rather than a problem specific to your system, and then change the bug status back to "New". For local configuration issues, you can find assistance here: http://www.ubuntu.com/support/community ** Changed in: docker.io (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1732914 Title: package docker.io 1.13.1-0ubuntu1~16.04.2 failed to install/upgrade: sub-processo script post-installation instalado retornou estado de saída de erro 1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/docker.io/+bug/1732914/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
