SugarPro-11.0.0.zip installer: PHP Sessions Configuration Error

The message in the error box was pretty clear. You need to correct your php.ini to point to valid directory. You might have issues in the future if you don't resolve the issue.

Thanks for your advice Jeff! Session.save_path already points to "/tmp" (see phpinfo excerpt below) and sugar actually saves sessions there, when install.php is called. The error is popping up nonetheless.

session-files saved to "/tmp" from starting installation:

Is there something else which has to be taken into account?

this is permission on your box, check the user permission and also the group

RUN chmod -R 777 /var/www /var/www/.* \
  && chown -R www-data:www-data /var/www /var/www/.* \
  && usermod -u 1000 www-data \
  && chsh -s /bin/bash www-data

I use sugardockerizer, and i have a very favorable user experience.

ok, hope you find a solution

Thanks Rodrigo Manara and Sanchez Jorge Luis! I tried resetting the permissions as suggested by Rodrigo Manara but no effect on the appearance of the errormessage. The strange thing is that up until this version of the installer, everything worked fine with my docker-compose setup.

I will try an installation directly on the host and the solution suggested by Sanchez Jorge Luis next, to further analyze the problem.

Thank you Sanchez Jorge Luis!
