Exception in grading container

Open nrybowski opened this issue 4 years ago • 5 comments

An error occurs in the grading container of the first task of the tutorial course. Here is the error displayed on the frontend:

Exception occured in container ([Errno 1] Operation not permitted: '/task')

Tested on a fresh install on c4c7bb0684bcfe1c2287a22b432d5488cda6c94e.

I'm not able to reproduce it. What is your operating system ? Do you have SELinux/AppArmor activated ? Are you able to launch SSH debug to see what /task looks like ?

INGInious is running in an Ubuntu 20.04 VM with AppArmor enabled. When I disable the docker-default profile and rerun a submission, the profile is reloaded and the container fails somehow. The SSH debug is thus not possible.

Does it work when you deactivate AppArmor completely ?

The strange thing is that I firstly disabled AppArmor completely and all the profiles were indeed disabled except the docker one.

This error seems to be due to permission issues with NFS, the task folder was mounted in the VM with NFS. It is not reproducible on a fresh Ubuntu 22.04 VM where the task folder is located on the local filesystem.
