Switched out to LineageOS 18.1 and ran into the same issue, but found a work around. Looks like they changed how the sdcard/partition is accessed in Android 11. Used to be able to access it via /sdcard or /storage/emulated/0, but now at least /mnt/runtime/full/emulated/0 drops to the sdcard partition without the Bad Address error. The only other catch is they also changed permissions on the sdcard and gave root and the everybody(9997) group read/write access instead of the sdcard_rw group. So, your primary user will need to be in that group(aid_everybody in the /etc/group) to be able to read/write it. Be warned though if my user is in that aid_everybody group linux deploy won't start for me. I have to reconfigure the profile and then start the profile, but that pulls my user back out of that group, so just need a script to put the user back in that group since Linux Deploy won't allow me to keep it as a privileged user/group in the profile settings(guessing that's a bug). Hope this helps.

Yes, it worked in LineageOS17.1/Android10, but it doesn't work in Android11 anymore. After upgrade I can access sdcard only if login as root.

mount your sdcard from chroot and not from linux deploy and add your user to group to get access read& write without root/sudo.

mine is /dev/block/by-name/userdata for sdcard and mount the device sudo mount /dev/block/by-name/userdata /media.

to get access read&write: sudo usermod -aG aid_media_rw,aid_system $USER <- $USER or specific user you want to get access read&write.

It works for me by following these steps in Linux Deploy v2.6.0:

1. Setting mount point

• Source: /data/media/0
• Target: /media/sdcard

2. Adding user to group aid_media_rw

• privileged users: android:aid_inet android:aid_sdcard_rw android:aid_graphics android:aid_media_rw

3. Tap STOP, run configure and then tap START ps: OnePlus 8T running OxygenOS(Android 11) tested

Thanks! It's worked for me!

Manjaro rootfs was easier to install than arch 🤔 (Because I didn't find clear aarch64 rootfs of archlinux 😅) And I had some issues with gpg, but it's easy to fix 😁

Just look for similar dirs..

[mio-19]

/data/media/0 is working, but it is creating permission problems. Android doesn't expect files in /data/media/0 have different owner
