This is getting more puzzling.
I checked that noacl was not set in /etc/fstab, it is not.
dumpe2fs looks right:
Code:
dumpe2fs 1.45.5 (07-Jan-2020)
Default mount options: user_xattr acl
The output of ls -lah also looks right:
Code:
/media/user:
total 8.0K
drwxrwx---+ 2 root root 4.0K Jun 12 20:50 .
drwxr-xr-x 11 root root 4.0K Dec 5 2020 ..
I spent a little bit of time looking into acl debugging, but they suggested the same steps you did. I'm going to look into it more tomorrow.
