Hi FWIW, I bootstraped a minimal VM running buster then:
apt-get --no-install-recommends install lxc-templates lxc debootstrap rsync and created lxc-create -n test-container -t debian -- -r sid The container start here with 1:3.1.0+really3.0.3-8. The updated the VM to unstable including the lxc packages. Container still start. And so as well a newly created container. All of the above in the VM with unchanged configurations. So even if downgrading packages on the affected host, this might be triggered due to something specific on the host. Regards, Salvatore
