Package: lxc Version: 1:3.1.0+really3.0.4-2 Upstream announced new LTS versions for LXC, LXCFS and LXD, see https://lists.linuxcontainers.org/pipermail/lxc-users/2020-April/015198.html Do you think it would be possible to upgrade the lxc and lxcfs packages for sid? I would be glad to help. Regards Harri
