[Bug 1591622] Re: Can't login to system, system is booting up error

[Martin Pitt]

Hello QkiZ, or anyone else affected,

Accepted console-setup into xenial-proposed. The package will build now
and be available at https://launchpad.net/ubuntu/+source/console-
setup/1.108ubuntu15.2 in a few hours, and then in the -proposed
repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to
enable and use -proposed.  Your feedback will aid us getting this update
out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, and change the tag
from verification-needed to verification-done. If it does not fix the
bug for you, please add a comment stating that, and change the tag to
verification-failed.  In either case, details of your testing will help
us make a better decision.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance!

Title:
  Can't login to system, system is booting up error

Status in console-setup package in Ubuntu:
  Fix Released
Status in console-setup source package in Xenial:
  Fix Committed
Status in console-setup source package in Yakkety:
  Fix Released

Bug description:
  [Impact]
  Regression in console-setup 1.108ubuntu15.1 in xenial-proposed which introduced a dependency loop caused logins to fail in around 10% of boots.

  [Test case]
  1) reboot
  2) attempt to login

  In the failure case, the system will display an error message:
  "System is booting up. See pam_nologin(8)."

  [Regression Potential]
  This is intended to fix a regression already found in xenial-proposed due to dependencies in the systemd units. Other ordering issues may arise, such that it is possible for another process to otherwise fail to load because of the invalid dependencies between systemd jobs. Care is to be taken in testing the proposed fix, and involves many reboot tests.

  ---

  On login screen (LightDM) I cant login to system because system error is displayed: System is booting up. See pam_nologin(8). This message is appearing randomly, sometimes when I boot system I can login and sometimes not. It starts to show after last console-setup-linux, console-setup and keyboard-configuration to version 1.108ubuntu15.1.
