I guess that's somehow possible with Jenkins only, but it most likely
requires twisting its semantics quite a bit. I'm happy to give
a closer look at it one of these days, in case there's a neat solution
to this problem => please give me a research ticket :)

However, long-term I think we'll have to use something like Zuul [1],
that's dedicated to orchestrating jobs and to mediating between our
Jenkins job needs, their result, and whatever action should be taken.
IIRC that's how the OpenStack project CI handles this kind
of problems.

On the short term, perhaps teaching APT or our build system to retry
such operations on failures would be a good enough, and muuuch
simpler, workaround.
