Cannot make container temp directory

[erelsgl]

I finally managed to register and submit the first task in the tutorial course. I received the attached error: "An internal error occurred. Please retry later. If the error persists, send an email to the course administrator. [Submission #603fbc2bc2d6716e5474e521]"

"Cannot make container temp directory."

There is nothing in the error.log.

I verified that my /var/www/inginious folder and all its subfolders are owned by the Apache user www-data.

As you're running with the local backend option, apache is the user who runs everything. Check that you have a

local-config:
    tmp_dir: /var/www/inginious/agent_tmp

entry with an absolute path in your configuration.yaml file. Otherwise you'll have the same issue than with the other folders.

This solved the problem. Thanks
