Original article, July 27, 2018 (3:54PM EST): If you look at the long list of devices that have LineageOS ROM builds, you’ll notice something strange: there’s no support for the Google Pixel, Pixel XL, Pixel 2, or Pixel 2 XL.
However, it looks like that is about to change, as the LineageOS team appears to have approved rolling out nightlies for the Google Pixel (aka “sailfish”) and the Google Pixel XL (aka “marlin”). Click here to check out the review history at LineageOS.org.
Although the original Pixel line will likely have LineageOS ROMs very soon, there’s still no word on the second-generation Pixel 2 line. But if the team can make LineageOS work on the original line, it stands to reason that they’d be able to make it work on the next line.
Strangely, there are plenty of custom ROMs out there based on Lineage OS for the Pixel line, but there hasn’t been an official one. It was only a matter of time before a bonafide version arrived.
LineageOS rose from the ashes of CyanogenMod, and is currently the most significant custom Android ROM in the custom ROM community. Using LineageOS, users can update old handsets to the most recent version of Android, as well as breathe new life into newer handsets that are lacking features or are bogged down with bloatware and ugly Android skins.
