I’m quoting myself:
Please note that the github master branches are development versions not officially released and where all the development is happening. Such versions might show unexpected behavior or could even break/be in a temporary unusable state at any time.
For productive use it is strongly suggested to stay with the official announced source code releases in About the Greenbone Community Edition category - Greenbone Community Edition - Greenbone Community Forum.
If you want to contribute to the development of those you probably need to dig into such issues on your own and could consider to contribute at the issue trackers of github: Greenbone · GitHub
As no help for such development versions should be given in this community portal i’m closing this thread.
Please switch to the stable branches as advised or try again in a few days / with a fresh git checkout of all branches.
