The issue has been resolved on repository side, which was not related to or in range of hestia. The update process is working properly, tested on ubuntu 18.04 and 20.04.
UPDATE: 10.3 and 10.4 are working properly, 10.5 and 10.6 are still buggy. We’re monitoring the situation.
UPDATE2: We reached out to mva with a request to fix their repository.
