Reminder to self: since the [ArchiveARM Cortex A53 problems are fixed, check out if this is also fixed:

Ubuntu: Fixing the myserious “Failed to stop apt-daily.timer: Connection timed out”

Posted by jpluimers on 2018/05/14

Ubuntu is the only Linux system I had that – after installing a text-mode console setup – gets itself in the below state with only running apt update and apt-get upgrade.

Preparing to unpack .../archives/apt_1.2.19_armhf.deb ...
Failed to stop apt-daily.timer: Connection timed out
See system logs and 'systemctl status apt-daily.timer' for details.
Failed to get load state of apt-daily.timer: Connection timed out
dpkg: warning: subprocess old pre-removal script returned error exit status 1

I could not find meaningful search results for the above thing, nor did systemctl status apt-daily.timer return anything better than

Failed to get properties: Failed to activate service 'org.freedesktop.systemd1': timed out

Heck, it doesn’t even reboot any more (no helpful search results either):

# reboot
Failed to start reboot.target: Failed to activate service 'org.freedesktop.systemd1': timed out
See system logs and 'systemctl status reboot.target' for details.
Failed to open /dev/initctl: No such device or address
Failed to talk to init daemon.

Nor did systemctl status reboot.target return anything better than

Failed to get properties: Failed to activate service 'org.freedesktop.systemd1': timed out

From the ubuntu-16.04-minimal-odroid-c1-20160817.img.xz base system, it only had these extra packages installed:

  • etckeeper
  • tmux
  • speedtest-cli
  • sendemail

Workaround found, but still unsure why this happened in the first place

Despite the workaround below, I still don’t know why I got into this situation and this leaves me with a very uncomfortable feeling.

Too bad some systems (like ODroid) only have Ubuntu based distributions as sorting out stuff like above took me way too much effort.
