[Bug 1887655] Re: unattended-upgrades triggers reboot despite configuration

Fri Mar 5 15:46:54 UTC 2021

Hi, why this has expired without any confirmation/non-confirmation? This
sounds like a terrible way to resolve bugs?!

I just had the same on a pretty vanilla 20.04 server which kernel was/is
compiled Nov 13 11:40:37 UTC 2020.

below command returns nothing:
apt-config dump | grep Reboot

also:
fgrep -i reboot /etc/apt/apt.conf.d/50unattended-upgrades 
// Automatically reboot *WITHOUT CONFIRMATION* if
//  the file /var/run/reboot-required is found after the upgrade
//Unattended-Upgrade::Automatic-Reboot "false";
// Automatically reboot even if there are users currently logged in
// when Unattended-Upgrade::Automatic-Reboot is set to true
//Unattended-Upgrade::Automatic-Reboot-WithUsers "true";
// If automatic reboot is enabled and needed, reboot at the specific
//Unattended-Upgrade::Automatic-Reboot-Time "02:00";

The only way I found out about this reboot was by looking into /var/log/syslog
Mar  5 12:57:44 ip-192-168-141-181 systemd[1]: unattended-upgrades.service: Succeeded.

After reboot I see packages are still pending so unlikely have updated anything:

The following NEW packages will be installed:

Title:
  unattended-upgrades triggers reboot despite configuration

Status in unattended-upgrades package in Ubuntu:
  New

Bug description:
  I've been having problems with my Ubuntu machine suddenly rebooting
  without any warning.  To my knowledge Ubuntu Desktop is not supposed
  to reboot without warning by default.

  I believe this is being triggered by unattended-upgrades

  unattended-upgrades 2.3 (amd64)

  Ubuntu Desktop:
  Description:	Ubuntu 20.04 LTS
  Release:	20.04

  One pattern that emerges is that the reboot happens right after
  unattended-upgrades completes successfully. There are multiple
  examples in my /var/log/syslog, but all show "unattended-
  upgrades.service: Succeeded." the same second everything begins to
  shut down, with nothing for a minute or two prior. Example:

  From memory I've never edited the contents of /etc/apt/apt.conf.d/ and
  the configuration for unattended upgrades claims to be default (NOT to
  reboot):
