Hi,

I would like to change the owner of a directory on the sdcard /sdcard/aDirectory

I have a terminal installed on my Android 10 (LineageOS 17) com.android.terminal

sudo is not present so I use su and it works.

su
#Terminal was granted Superuser rights

cd /sdcard
chown 10:10 aDirectory
#I don't get any error message.

stat aDirectory
#Uid (0/root)

So the owner stay root no matter what I’m doing, any ideas ?

    Android users all kinds of overlays over the sdcard directory. This is part of how it enforces storage access for apps. There’s probably a way to override these settings, but they sure as hell aren’t easy.

    There’s also another layer of permissions somewhere seeing as I can’t access certain files on /sdcard that were created by the recovery. I assume it’s an selinux context issue (it always is).

    Changing ownership should work on real SD cards with normal storage, but it won’t for the emulated internal /sdcard.
