Upgrading PHP from 7.3 to 8.0 using NGINX and Debian

AdamXweb

This is more to document my experience upgrading from v0.16.0 beta to v1.0.4, which also required me to update the php version.

When typing php flarum info the php version came up as v8.0.8.
However before upgrading the flarum dashboard would show 7.3.

After a bit of digging, the nginx sites-available flarum.conf stated:
fastcgi_pass unix:/run/php/php7.3-fpm.sock;
Had to update it to:
fastcgi_pass unix:/run/php/php8.0-fpm.sock;

Hope this can help someone else that's rather new and stuck on why it isn't updating.

Glad you got it working!

We do still support PHP 7.3 though, so it's a bit strange if you had issues with that version.

The important thing about PHP versions is to make sure the same version is used on the web (php-pfm) and on the command line (php-cli). If the command line version is more recent than the web version, then Composer will install dependencies that might not be compatible with the web server PHP version. When the command line version can't be changed, composer can be called with a particular PHP version with php7.3 composer <command>. Exact syntax may vary on some hostings.
