<html><head></head><body><div style="font-family:Helvetica Neue, Helvetica, Arial, sans-serif;font-size:medium;">I have been running lxcs for over a year without issues on an Odroid-C2 running Arch ARM (aarch64). Recently, I am unable to start any of the containers due to some errors around cgroups. This happened today after an update where 4 packages got updated but note that downgrading them back to the last-good versions and a reboot did not fix the problem. I am not finding anything contemporary when googling for causes. Advice is appreciated.<br><br><br>libsystemd (232-8 -> 233-6)<br>systemd (232-8 -> 233-6)<br>device-mapper (2.02.171-1 -> 2.02.172-1) <br>python2 (2.7.13-2 -> 2.7.13-3)<br>systemd-sysvcompat (232-8 -> 233-6)<br><br><br>Below is an example of the error when starting in foreground mode:<br><br><br># lxc-start -n base-odroid64 -F<br>systemd 233 running in system mode.
