Hi,
The Mstflint accepted into UB proposed repo in both ubuntu 18.04 and 19.10.
So now we have an official UB release that we must run a full QA cycle on it
and once we verify it.
The package will be added to the Update repo in 7 days after our approval.

Hi Christian,
yes that exactly what we see in our tests,
so are the logs that you asked for in comment#1 still needed?
