Maybe it is same root cause as HaaS je funkční. I noticed some script (related to turris 1.x, on Omnia need to be aproved to participate on project) gets enabled in one of previous updates 3.9.x I believe. I think nikola is in the same category of “features”.
Its just blind unexperienced guess, but I know devs try to merge Turis 1.x and Omnia branches together, and that symptoms makes me feel as some of Non-participated Omnia’s gets something by mistake.
