** Description changed: Problem description: Upgrading lxd-agent-loader package causes a restart of the lxd- agent.service. This service restart can be problematic when the apt upgrades are done through a `lxc exec` session as the session gets killed/disconnected abruptly. This is what caused https://bugs.launchpad.net/ubuntu/+source/lxd-agent-loader/+bug/2078936 for example. Motivation for the FFe: This behavior of restarting on package upgrade is problematic especially when it happens during do-release-upgrade as it's not obvious how to reconnect or pick up where the session was disconnected. As such, the end goal of that FFe is to land the fix in Oracular and do a SRU to Noble to address the Jammy->Noble upgrade issue it causes. Additional information: lxd-agent-loader authoritative sources live at https://code.launchpad.net/~git-ubuntu-import/ubuntu/+source/lxd- installer/+git/lxd-installer/+ref/ubuntu/devel so this is not a new upstream release per se. As such, the only changelog would be: * d/rules: don't stop lxd-agent on upgrade (LP: #2078936, LP: #2079406) - This changelog and associated changes are being proposed for merging in - https://code.launchpad.net/~sdeziel/ubuntu/+source/lxd-agent- + This changelog and the associated changes are being proposed for merging + in https://code.launchpad.net/~sdeziel/ubuntu/+source/lxd-agent- loader/+git/lxd-agent-loader/+merge/472700 + + The changes themselves are simply to skip the stopping of the lxd- + agent.service unit on upgrade as otherwise, stopping that service is + risking to kill an active `lxc exec` session. As the d/changelog indicates, this is a bugfix-only update.
