Sorry, but LineageOS is pretty much a joke now. Most maintainers just randomly stop maintaining devices after a little bit of time. Also, there is shady stuff at the limits of legality when it comes to proprietary binaries. They preach security is their focus, but doesn't look like that.
Also, vendor roms are quite good already, no need to install unstable roms like it's 2015.
