Edited on June 16, 2021

LineageOS is a free, community built, aftermarket firmware distribution of Android 9, which is designed to increase performance and reliability over stock Android for your device.

LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.

Reporting Bugs

Don’t report bugs if you have any custom kernel or module installed
Create new issue here.
Grab a logcat right after the problem has occurred. (Please include at least a few pages of the log, not just the last few lines, unless you know what you’re doing.)
If it is a random reboot, grab /proc/last_kmsg. (Do not bother getting a logcat unless you can get it just before the reboot. A logcat after a reboot is useless)
If the problem disappears after running “setenforce 0” from a root shell, grab /proc/avc_msg.
