Mine didn't get passed Remounting /system to rw ... mount: can't find /system in /proc/mounts

Anyway,
On my hero2lte running ice cold project(android 10) I managed to install bysybox by cloning this project, replacing this busybox mount -o rw,remount /system line in install.sh with
busybox mount -o rw,remount /dev/block/platform/155a0000.ufs/by-name/SYSTEM /
I compiled the app and ran it from android studio, installation worked.

I examined the /proc/mounts for the SYSTEM location.
hope this helps

That helped, thanks. I will leave this issue open as I think this should be implemented inside the app

Hello, I just wanted to confirm that this fix works perfectly on Android 11 (Lineage 18.1 (2021-06-15)). Thanks to Damjan94 for whatever magic they did to fix this, and spending the time to share it.

I used AEE(APK Eplorer & Editor v.14 from F-Droid) by sunilpaulmathew to recompile the app(BusyBox 1.31.1 from F-Droid) with changes to install.sh, It works perfectly.

Quick lazy misspelled guide for whoever happens to have the same issue and does not want to deal with android studio:
open AEE (https://github.com/apk-editor/APK-Explorer-Editor)
search for BusyBox then click on it
open assets/all/scripts
then click on the 6 dots to the right of install.sh and export.
find where it was exported (by default its "AEE/ru.meefik.busybox")
edit install.sh with Damjan94's changes:

replace busybox mount -o rw,remount /system line in install.sh with
busybox mount -o rw,remount /dev/block/platform/155a0000.ufs/by-name/SYSTEM /

save the file then go back to BusyBox click the 6 dots then click replace.
navigate to the above path and click on the install.sh file you modified.
click the hammer, click save, then click "APK's" and click on BusyBox and then install.

I have no idea why Damjan94's fix works but if possible please or add an option to edit install.sh or autodetect the android version and swap to the modified script.

Use LineageOS with Magisk.
