dnsmasq-2.86 shipped in Ubuntu jammy has a known issue[1] which is fixed in dnsmasq-2.87 but it's not yet released with Ubuntu jammy. Until fixed version is available in Ubuntu jammy let's use source install instead of using a older version from Ubuntu focal. [1] https://lists.thekelleys.org.uk/pipermail/dnsmasq-discuss/2022q3/016562.html Update from Julia: Pushing forward the source fix again as ubuntu removed the prior path we were using as a focal package and replaced it with a package which is demonstrating the same basic issue.
