Hatte ich auch beim Samsung Galaxy Note 10.1 2014 Edition. Bei mir kann es über OTA Updater nicht upgedatet werden, sonder ich muß es dann mit TWRP flashen. Wird mir aber auch nach Download und starten des Update mitgeteilt. Habe dazu dies in Englisch gefunden. Habe dies gestern durchgeführt, wie vorher gesagt bei meinem Samsung.
Below is the how-to for those who are not familiar with using the built-in LineageOS (LOS) Updater and TWRP to update LOC nightly to the latest nightly.
Requirements
LOS 14.x nightly
A recovery tool already installed. Such as TWRP (The Win Team Project) at
http://www.teamw.in/project/twrp2/
That tool is free, owned, and supported by a community.
Steps
Using LOS:
Navigate to Settings -> About phone -> LineageOS Updates
Download the most recent LOS. Optionally watch the "Download Manager" for that zip file progress.
After that download is successful it will automatically ask you if you want to reboot in recovery mode. Do so.
The device will boot with TWRP
Using TWRP:
That's optional but it's suggested to backup your valuable data. To do so tap on "Backup" button.
To update LOS. Tap "Install" button.
Select the newer zip file you just downloaded. Usually it's located at "/data/data/org.lineageos.updater/app_updates/lineage-14.1-************.zip"
Uncheck "Zip signature verification". Because presently the LineageOS do not come with a MD5 file.
Swipe to confirm Flash
Wait. LOS needs 1 to 5 minutes. Depending on your device.
Ignore the two red error messages "E:unknown command [log]"
When done tap the "Reboot System" button
The reboot will be very slow. LOS needs time to complete the update. The LOS animated logo will be display during the progress. Be patient.
No need to reinstall GApps
Done. You have successfully updated your LOC nightly. Enjoy
