Hi @mandelkow, this looks like an issue with your package manager. Is that something you can configure on the instance? Have you checked Sagemaker Classic documentation?

[mandelkow]

Running apt-get update before the installation solved the installation problem.

Alas, mountpoint-s3 <bucket_name> <mount_point> still won't work inside a Sagemaker kernel instance.
According to some internet sources the following error is related to running a Docker container with limited permissions.

fuse: device not found, try 'modprobe fuse' first
Error: Failed to create FUSE session
 
Caused by:
    No such file or directory (os error 2)
Error: Failed to create mount process

You are right, in order to use Mountpoint in a container, Docker needs to be configured with --cap-add SYS_ADMIN --device /dev/fuse (see docs for more details: https://github.com/awslabs/mountpoint-s3/blob/main/docker/README.md).

Of course, that may not be supported when using a service like Sagemaker.

Thanks for updating the issue. I'll close it now as not specific to Mountpoint.
