I verified the Groovy SRU (for 0.102-0ubuntu1~20.10.3) and attached the corresponding test logs to the bug description.

[Bug 1922898] Re: [SRU] SEGFAULT on upgrade to 0.102-0ubuntu1~20.04.1
** Description changed: [Impact] This release contains a regression bug-fix for un-breaking the ABI compatibility between libnetplan 0.102 and netplan.io 0.101, which was taken from a pending upstream pull request: https://github.com/canonical/netplan/pull/206 (d/patches/fix-lp1922898) [Test Plan] The following development and SRU process was followed: https://wiki.ubuntu.com/NetplanUpdates Netplan contains an extensive integration test suite that is ran using the SRU package for each release. This test suite's results are available here: http://autopkgtest.ubuntu.com/packages/n/netplan.io A successful run is required before the proposed netplan.io package can be let into -updates. The netplan team will be in charge of attaching the artifacts and console output of the appropriate run to the bug. Netplan team members will not mark ‘verification-done’ until this has happened. Additionally, we want to manually verify the ABI compatibility (i.e. not SEGFAULT) between the new libnetplan and the old netplan.io "generate" binary, with the steps described below: * Have netplan 0.101 installed * Upgrade ONLY libnetplan0 to 0.102 $ cat /etc/netplan/00-config.yaml network: ethernets: ens5: dhcp4: true dhcp6: false match: macaddress: 06:f8:32:e5:34:28 set-name: ens5 version: 2 $ /usr/lib/netplan/generate * Make sure the "generate" binary did not crash. [Where problems could occur] Netplan being a core package it could impact the whole networking stack of the operating system up to the point where servers would not be reachable anymore after a reboot, due to broken network config being generated by netplan at bootup. In order to mitigate the regression potential, the results of the aforementioned integration tests are attached to this bug. Additionally, this SRU needs to drop the "Added ttl option for tunnels (LP: #1846783)" feature, added during the 0.102/Hirsute development cycle. So users of the -devel series using the new "tunnels.ttl" setting are going to miss this until it is re-implemented in an ABI preserving way.
