As I wrote in comment #15, we don't have a viable workaround yet that doesn't inroduce other hangs / failures in other scenarios. A "fix" that will break all ability to further upgrade the system is worse than the status quo, because it means security fixes can't be applied.
Until someone is able to identify a solution that doesn't have this disadvantage, there's nothing that can be done here.
> Lucid is an LTS release and as such should be stable for 2 years.
"stable" does not mean "usable for all proposed uses".
