first of all, thanks for the reply,
and I tried all 3 commands … lol
and restarted the XAMPP server.
Still the permissions arent given to OctoberCMS.
➜ ~ sudo chown -R root:root /opt/lampp/htdocs/buddhistblog
[sudo] password for zhouxiang:
➜ ~ sudo chmod -R 755 /opt/lampp/htdocs/buddhistblog
➜ ~ sudo /opt/lampp/lampp stop
Stopping XAMPP for Linux 7.4.1-1...
XAMPP: Stopping Apache...ok.
XAMPP: Stopping MySQL...ok.
XAMPP: Stopping ProFTPD...ok.
➜ ~ sudo /opt/lampp/lampp start
Starting XAMPP for Linux 7.4.1-1...

➜ ~ sudo chown -R www-data:www-data /opt/lampp/htdocs/buddhistblog
➜ ~
all of those commands worked… I got a little green arrow on my ohmyzsh theme, which indicates it should worked.
