Balint Reczey: New tags on the block: update-excuse and friends!
In Ubuntu’s development process new package versions don’t immediately get released, but they enter the -proposed pocket first, where they are built and tested. In addition to testing the package itself other packages are also tested together with the updated package, to make sure the update doesn’t break the other packages either.
The packages in the -proposed pocket are listed on the update excuses page with their testing status. When a package is successfully built and all triggered tests passed the package can migrate to the release pocket, but when the builds or tests fail, the package is blocked from migration to preserve the quality of the release.
Sometimes packages are stuck in -proposed for a longer period because the build or test failures can’t be solved quickly. In the past several people may have triaged the same problem without being able to easily share their observations, but from now on if you figured out something about what broke, please open a bug against the stuck package with your findings and mark the package with the update-excuse tag. The bug will be linked to from the update excuses page so the next person picking up the problem can continue from there. You can even leave a patch in the bug so a developer with upload rights can find it easily and upload it right away.

Boeing CEO Accused of Telling 'Half-truths' in 737 MAX Hearing
The hearing, the highest-profile congressional scrutiny of commercial aviation safety in years, heaps pressure on a newly rejiggered Boeing senior management team fighting to repair trust with airline customers and passengers shaken by an eight-month safety ban on its 737 MAX following the crashes, which killed 346 people.
"You have told me half-truths over and over again," Senator Tammy Duckworth told Muilenburg, questioning why the manufacturer did not disclose more details about MCAS's lack of safeguards. "You have not told us the whole truth and these families are suffering because of it."
Duckworth said the pilots did not know enough about MCAS.
"You set those pilots up for failure."
