26.0.0-BETA.2 Containers not accepting shutdown commands?

I’ve just noticed that it seems like none of my Ubuntu Resolute Containers appear to be accepting shutdown commands. If I issue a shutdown command from the GUI, (or if my UPS is about to die and needs the server to shutdown gracefully!) the containers have no idea until their kill timer elapses and they get killed.

If I ssh into the container environments a simple sudo shutdown now works exactly like one would expect. Where would I start troubleshooting this?

First thing i would do is take a look at the release notes of beta3 and see if anything container related got fixed there. If there’s no mention of a fix my next step would try to update to beta3, see if it’s already fixed in beta3. If yes, good, if no file a bug report for beta3
