Same here: Many machines with unattended-upgrade (UU). Some Focals upgraded both netplan.io & libnetplan0 in tandem to 0.102, others left both packages at 0.101, probably depending on when they ran UU and what state the APT mirrors where at at that time. All those machines were fine.
One machine however upgraded only libnetplan0 to 0.102 and left netplan.io at 0.101, which broke netplan (segfault) and rendered the machine offline. Installing netplan.io 0.102 manually from focal- proposed fixed it. I wonder whether retracting 0.102 from focal-updates might have actually worsened the situation and left even more machines with different versions of netplan.io & libnetplan0. It definitely made it harder to rectify. Is it adviced to use Unattended-Upgrade::MinimalSteps "false"; or would that have its own pitfalls? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1922898 Title: SEGFAULT on upgrade to 0.102-0ubuntu1~20.04.1 To manage notifications about this bug go to: https://bugs.launchpad.net/netplan/+bug/1922898/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
