Django mod_wsgi Apache error 403 Forbidden on Ubuntu 22.04

Question

Django mod_wsgi on Apache application works fine in Ubuntu 20.04 and previous versions with the configuration mentioned below, but when I do the same configuration in Ubuntu 22.04 it gets 403 Forbidden error . and Permission denied: mod_wsgi in the error log.

I tried changing permission on all files it's doesn't work,

Apache config:

<VirtualHost *:80>
        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined

        <Directory /home/ubuntu/mydjango/mydjango>
                <Files wsgi.py>
                        Require all granted
                </Files>
        </Directory>

        alias /static /home/ubuntu/mydjango/static
        <Directory /home/ubuntu/mydjango/static>
                Require all granted
        </Directory>

        WSGIDaemonProcess myapp python-home=/home/ubuntu/mydjango/venv python-path=/home/ubuntu/mydjango
        WSGIProcessGroup myapp
        WSGIScriptAlias / /home/ubuntu/mydjango/mydjango/wsgi.py
</VirtualHost>

By default Apache2 run as www-data user that does not have permission (read/execute) to home directories. So you should set the correct permissions also on the home directory:

sudo chmod 755 /home/ubuntu

Or you can put the project into eg /var/www that is readable/executable by 'others' by default, so Apache2 can run the project from there.
