I have just dual booted my first linux system a couple of days ago, and now I am trying to install LAMP through this link : https://forum.manjaro.org/t/howto-install-apache-mariadb-mysql-php-lamp/13000
However, I can not write into the httpd.conf file. I’ve been searching for hours now. Ensured that I had write access, and that there were no immutable bits. What can I do?
