I am planing on hosting my laravel application on my RaspberryPi that's connected locally. I have my DynDns domain setup and everything. Now i just need to get PHP7.2 on my raspberry and from what i've i need to add buster to my repository list and then i should be able to get PHP7.2 but i get the following error when i run the command to install php7.2:
The value 'buster' is invalid for APT::Default-Release as such a release is not available in the sources
I'm not sure how to continue with this, how i can fix it and why this is happening. Note that i used this guide to set up buster. You can scroll down to "Install PHP 7.2" to see what i have done.
