Wrong access rights in Docker container: Permission denied: '/app/UltraSinger/src/.local'

[riogrande75]

I've just installed latest docker container with podman and started ultrasinger.
I correctly maped host dir's into docker and gave permission on host side (777).
But when I start UltraSinger process (inside Docker with std. user 1000) the temporary files get written from docker's root and so the process crashes with permission denied:

Model was trained with torch 1.10.0+cu102, yours is 2.3.0+cu121. Bad things might happen unless you revert torch to 1.x.

Any Idea how I could get over that? Maybe someone knows the root passwort, so I would start UltraSing as root inside docker.
