Are your server permissions correct? Try chmod 777 on the installation directory untill you have it installed then change it to a more secure setting.
Find out what user your web server is running as. Most linux distros run as www-data
chown -R user_name:user_name *
OR
chown -R www-data:www-data *
chmod -R 775 *
Those two commands should fix your problem. A short note on *nix commands:
chown = change owner
chmod = change mode
The -R makes both recursive through the entire file tree from where you start.
The * means match everything that’s not a . file like .htaccess
