Lineage Os 14.1(7.1.1) Problem With Rooting - Galaxy S III Q&A, Help & Troubleshooting

I had recently upgrade my s3 using TWRP recovery from 4.4 to 7.1 lineage os
But I am facing problem with rooting.
I am not able to root my device from
1)TWRP recovery
2)Odin(CF Auto Root)
3)Kingroot(Android and PC )
I have installed TWRP properly
PLz give an idea to root my device
I have checked in developer option
That is ROOT ACCESS
Their is 2 Option only
1)Disable
2)Adb only
But I am not able to get root access any of this Or Adb only
Previously I tried with different ROM
Their is option of
1)disabled
2)Apps only
3)Adb only.
4)apps and Adb
But in this ROM I am not able to find suggest me any way to fix this
I installd 4 time s same ROM to get this root access but failed
Check below screenshot
In SuperSU application
No su binary installed

As far as I'm aware the rom should be pre rooted and all you'll need to do is install supersu from googleplay and then update the su binaries from within the supersu app.
Set it to option 4 (apps and abd) and go about installing supersu first as the app from googleplay and if no joy then as a flashable zip file.

Did you try to flash the addonsu.zip from LineageOS website?
You must flash it to get root access in LineageOS 14.1

Are you sure you flashed the correct addonsu???
As far as i remember, the s3 doesn't have 64x, flash the normal arm version (arm32x).

Bro i have tried to flash ARM AND ARM X86 but it says
update failed in twrp recovery
So i flashed with x64
It was done but not worked properly

It works, you will get an error in recovery, but when you boot, you will get root access normally, i don't why the error happens, but it's harmless anyway.

Root fix
I'm not sure if you have fixed it yet but just in case if this helps the way I got around this is by simply downloading the latest super su zip from the official site and manually flashing via twrp kinda sucks but it works the first boot took a little though so if you try this and it takes forever for your device to not just wait because it can take up to 15 min the first time. So basically as long as you have twrp you are rooted technically it's just based on the rom wether they chose to support it if not the zip always works but you need the app too.

S3 has arm32. So neither x86 not x64 would work. You should've flashed addonsu.zip for 32.
