Thanx Dmitriy, I will give this method a try.

Sorry for the late reply. I did upgrade that following way with ad-hoc command: cd /opt/openstack-ansible; ansible -m package -a "name=ca-certificates state=latest update_cache=yes only_upgrade=yes" all But eventually the correct way probably would be updating LXC image and re-creating containers. This is not really realistic scenario though. 04.10.2021, 16:11, "Taltavull Jean-Francois" <jean-francois.taltavull at elca.ch<mailto:jean-francois.taltavull at elca.ch>>: Hi All, Following the recent Let's Encrypt certificates expiration, I was wondering what was the best policy to apt upgrade the operating system used by LXC containers running on controller nodes. Has anyone ever defined such a policy ? Is there an OSA tool to do this ?
