Singularity error: Failed creating home directory in container

Using Singularity, I have managed to build a container from DockerHub, shell it with Sudo, successfully installed some software, and even run it with Sudo. However, when I try to shell it as an unprivileged user, it gives me an error :(
Could someone help me in this? Thank you!

The error is as follows:

Code:

do you really want to create that directory in your container? (ERROR : Failed creating home directory in container /var/lib/singularity/mnt/final/home/AD/praposo: Operation not supported)

Hi. I don't wish to create the directory but it seems that just by 'shelling' the container using singularity, it automatically attempts to create it. Maybe it attempts to mount the home of the user (?), but I don't know.

I would rather say you have misconfigured something. I don't think you really need that dir.

Thank you pan64 :hattip:! You made me think of the problem in a different way. I figured out that by using the '--writable' option in the 'singularity shell' command, it allows any user to create directories. Maybe you're right and I don't need to create that directory but I don't know how not to, since it tries to do it by itself. But we found a solution to this, so I'm going to close this thread.

Cheers
