Today we will give you a few important comand lines for your next SSH session you will need one day when you run your own server. Let's cut the text and get straight to work.
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
sudo apt-get clean
sudo apt-get autoclean
sudo apt-get autoremove

du -h --max-depth=1 /home/ | sort -h -r
This will give you the folders inside home in a human readable way.
sudo chown -R admin:www-data /var/www/html/files
This will set the owner:group for the files directory recursive.
sudo chmod -R 2755 /var/www/html/files
Set permission for the files directory recursive.
sudo chmod -R g+s /var/www/html/files
This will set files and everything inside to be owned by the group set above.
