In practice, this manifests on at least Xubuntu upgrades during the chromium-browser snap transition. [Test Plan] Without this fix, the snap store connectivity check will fail when installing the chromium-browser snap because systemd-resolved is not present, so DNS lookups fail during the connectivity check. With the fix in place, the systemd-resolved stub resolver should be disabled during the upgrade so that DNS lookups succeed even when systemd-resolved is not yet unpacked on the system again. So, to test this fix, we should run an upgrade on a Xubuntu 22.04 system: $ do-release-upgrade -d And verify that (a) the chromium-browser installation (and snap store connectivity check) succeeds, and (b) that the stub resolver is not in use during the upgrade. $ cat /etc/resolv.conf $ cat /run/systemd/resolved.conf.d/dist-upgrade-no-stub-resolver.conf [Where problems could occur] This patch disables the systemd-resolved stub resolver by writing a drop-in to /run/systemd/resolved.conf.d. If there was a mistake in the drop-in, it would not correctly disable the stub resolver. [Original Description] When running `do-release-upgrade -d` on Jammy Xubuntu, the upgrade fails consistently at the `Installing the firefox snap` step. This was first detected on Jenkins [1], then reproduced locally with `auto-upgrade-testing`, then finally by manually running a `do- release-upgrade -d` in a VM.
