Hello @viktor,
You are using branch HBL. This branch is suggested to be used by experienced users. For now, you can find there Turris OS 5.1.0 in the development stage. Occasional bugs like packages are not built or things do not work there are expected. We know that and that’s why it is mentioned in our official documentation [1] and switch-branch [2].
Users do not mind a few bugs, which might happen as they want to test the latest features, which we are preparing.
If packages are not built, that’s should be easy to fix and you might want to send us pull request. But don’t worry, I fixed that [3] for you. I think it was not hard to add just one row even during Easter time.
