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

[QkiZ]

[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.

Me too for the last three days since 10.6.2016.

resolved by rebooting, after 1-2 tries its starts OK

[QkiZ (qkiz)]

I'd downgrade console-setup-linux, console-setup and keyboard-configuration to 1.108ubuntu15 and everything back to normal.

[QkiZ (qkiz)]

* I downgraded ...

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[Chris Taklis (aka Kailor) (ctaklis)]

@QkiZ (qkiz) how do you downgrade? because it affected me too today!

[QkiZ (qkiz)]

Downgrade:
sudo apt-get install console-setup-linux=1.108ubuntu15 console-setup=1.108ubuntu15 keyboard-configuration=1.108ubuntu15

Block updates for packages:
sudo apt-mark hold console-setup-linux console-setup keyboard-configuration

[Gerard Louw (gerardlouw)]

Also just got greeted by this message. QkiZ's fix seems to work for me as well (for the last few reboots), but given the sporadic nature of the bug I can't be sure.

[QkiZ (qkiz)]

It must be tested for next week, I think.

[QkiZ (qkiz)]

I have another bug related to console-setup package but now I'm testing it. I will make another bug report for this package.

This is a regression in proposed, not updates.

[QkiZ (qkiz)]

Which package have regression? And in which version?

[Martin Pitt (pitti)]

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.

Hi,

This package fixes the bug for me

console-setup : 1.108ubuntu15.2

Thank you!

[QkiZ (qkiz)]

I have enabled proposed repo already. For two reboots I haven't problems. But this require more reboots to confirm. I will use system for few next days and add post if problem is resolved.

[Marina Hildebrand (marina071170)]

looks good so far. Had this bug on 3 of my machines and it seems Ok now.
But as QkiZ already says, this will need some more testing

[QkiZ (qkiz)]

I think that 1.108ubuntu15.2 version resolve problem.

[Launchpad Janitor (janitor)]

This bug was fixed in the package console-setup - 1.108ubuntu15.2

---------------
console-setup (1.108ubuntu15.2) xenial; urgency=medium

  * Reorganize and correct console-setup, keyboard-setup and setvtrgb along the
    lines of the logic in 16.04: (LP: #1591622, #1593156)
    - debian/console-setup-linux.setvtrgb.service: don't require being run
      before system-getty.slice.
    - debian/keyboard-configuration.links: both console-setup and
      keyboard-setup systemd units should be installed to sysinit.target rather
      than multi-user.
    - debian/keyboard-configuration.keyboard-setup.service: move loadkeys call
      at local-fs-pre.target and in this more suitable location.
    - debian/keyboard-configuration.console-setup.service: move to running
      after the screen, keyboard, and filesystems are ready and set up all of
      what may still need to be done to configure the virtual consoles
      appropriately: set a final keymap, font, etc.

console-setup (1.108ubuntu15.1) xenial; urgency=medium

  * debian/console-setup-linux.setvtrgb.service: port the upstart job for
    applying our preferred color settings to a systemd unit so it gets run.
    This will fix debconf prompts on console being extra ugly. (LP: #1576893)
  * debian/console-setup-linux.links: enable our setvtrgb service in sysinit.
  * debian/keyboard-configuration.links: fix link source for console-setup
    service. (LP: #1572697)
  * debian/control: add dh-systemd to Build-Depends.
  * debian/keyboard-configuration.keyboard-setup.service: also enable
    keyboard-setup as a systemd service so we can have proper keymaps enabled
    in VTs. (LP: #1579267)
  * debian/keyboard-configuration.links: enable keyboard-setup service.
