Thanks for the reply.
(1) As I have said earlier it is NOT even available at all. Not even in the form of "greyed-out". It is just not there.
(2) The reason I started looking for "manage root accesses" is because:
TLDR:
Edit: I've granted USB debugging / ADB permission to both my computers already, and was still getting permission errors.
LineageOS Sep 19 ROM update failed, phone wouldn't boot. I kept getting these errors:
Code:
from TWRP: Error 7 or from a computer:
db: sideload connection failed: insufficient permissions for device: user in plugdev group; are your udev rules wrong?
I searched for a while to resolve the issue and most my searches lead to "
granting root access to ADB / manage root accesses". So I was trying to prevent this from happening again, if the cause was "not granting root access to ADB".
Posting the details here for anyone that may come across with similar issue:
On Sep 19, when I tried to update official LineageOS ROM from Aug 09 to Sep 19, through TWRP (that's how I've been updating for 2+ years), the update failed first time ever for me.
Afterwards phone couldn't boot, was getting stuck at Lineage logo for 30+ minutes. So I tried flashing new (and later old ROM too) ROM through computer. I tried both from Ubuntu 19.04 terminal (
after first becoming root user),
and from Windows 10 (administrator command prompt).
The "adb sideload" was failing with this errors:
Code:
[email protected]:/home/admn/Downloads# adb sideload lineage-16.0-20190919-nightly-natrium-signed.zip
adb: sideload connection failed: insufficient permissions for device: user in plugdev group; are your udev rules wrong?

adb: trying pre-KitKat sideload method...

I tried from TWRP again, and this time tried to install Aug 09 ROM and I was getting "Error 7".
So I had to "clean install" MIUI 10 9.6.27, then formatted, advanced wipe, and tried to flash through "adb sideload" but it failed even after all these. This time I was getting different error:
Code:
[email protected]:/home/admn/Downloads# adb sideload lineage-16.0-20190919-nightly-natrium-signed.zip
adb: sideload connection failed: no devices/emulators found
adb: trying pre-KitKat sideload method...
adb: pre-KitKat sideload connection failed: no devices/emulators found
Finally I was able to flash Sep 19 ROM (and Open Gapps & Magisk) through USB OTG.
