That wouldn’t be recommended. I suggested switching branches as you want access to newer packages than the stable branch currently has. I switched to the testing branch over a year ago and have had no issues in that time.
I was asking to compile rc kernel from kernel.org using the kernel-action github action from manjaro-kernels github repo. but I do not know if it causes any change on your side. That’s the question I am asking that can I use the github action?
XY Problem detected. You’re asking about your attempted solution rather than your actual problem. This leads to enormous amounts of wasted time and energy, both on the part of people asking for help, and on the part of those providing help.
You don’t need to build 6.4-rc1 yourself if you want to test it. All you have to do is switch to the unstable branch and install it.
By the way, you can use our GitHub CI to build it yourself. You just have to fork it and run it yourself.
