problem and solution when upgrading MOODLE_311_STABLE to MOODLE_401_STABLE

cprima

Just wanted to mention that when upgrading MOODLE_311_STABLE to MOODLE_401_STABLE I got an error

Invalid permissions detected when trying to create a directory. Turn debugging on for further details.
and debugging then brought
The file cache store path is not writable for TMPFS application

I outputted the problematic path in the debug message and it turned out that
/var/cache/moodle/application
was causing the issue. I gave that directory a generous 0777 and then the update could proceed.

Couldn't find that somewhere else on the internet, might be helpful for other users.

cprima It would be great to know which steps you did for the upgrade.

If you did the things from Nicolas' upgrade guide https://moodlebox.net/en/help/moodle-version-update/ then everything should work fine

sudo -u www-data -g moodlebox git config remote.origin.fetch "+refs/heads/*:refs/remotes/origin/*"
sudo -u www-data -g moodlebox git fetch origin
sudo -u www-data -g moodlebox git checkout MOODLE_401_STABLE

After these terminal commands Nicolas writes to open http://moodlebox.home/admin/ in your browser to start the upgrade in the browser. In this case the installation runs with the server rights of the user www-data and everything is okay.

If you complete the installation in the terminal you need to use also the user www-data.

sudo -u www-data -g moodlebox php /var/www/moodle/admin/cli/upgrade.php

If you run the Moodle script upgrade.php with the rights of the user root you will get the folder /var/cache/moodle/application with an exclusive root access. Please read the https://docs.moodle.org/401/en/Administration_via_command_line#Running_CLI_scripts for this fact.
