[SOLVED] Only front page available, other menu items gives 'not found 404'?

I am trying to install drupal on raspberry pi 3 with nginx and raspbian.

The installation was finished but there is only front page and every menu’s tab gives ‘not found 404…’

I followed this tutorial: https://www.linuxbabe.com/linux-server/drupal-8-ubuntu-16-04-nginx-maria…

BTW: How can return to installation stage?

Please advise!
