ketronixdev Yes I tried it, but using the unstable repo it doesn't build. But I can now finally build it, using solbuild and the main profile.
Edit:
@ketronixdev Btw. I understand that you probably don't like the teams decision. But it's a rule here which I personally can understand. There's only a small amount of people involved in this project and if users start using repos not maintained by the team, it's very hard to give support in the forum. Especially if someone is using a repo with core things like the kernel.
