nginx needs to be configured for php8.1 with version 3.7.0

[nomisma-qt]

Hello. I got LXD-Dashboard installed in a Proxmox LXC container, and now have access to the GUI. Looking forward to start testing.

I just wanted to note that following the installation to a LXC container guide, nginx comes with php7.4 enabled by default, this results in a 502 Bad Gateway when accessing the GUI.

It's fixed easily by editing /etc/nginx/sites-enabled/default

#fastcgi_pass unix:/run/php/php7.4-fpm.sock;
   fastcgi_pass unix:/run/php/php8.1-fpm.sock;

For anyone looking to install in Proxmox, here's a quick guide:

1. Set up a ubuntu 22.10 container, and enable options: nesting=1,fuse=1

2. quick setup. Yes, snap install core must be done twice, the first time will result in error, second time will work.

apt update && apt upgrade
dpkg-reconfigure tzdata
do-release-upgrade
apt install snapd
snap install core
snap install core
snap refresh core
snap install hello-world
hello-world

snap install lxd
apt install nginx php-fpm php-curl sqlite3 php-sqlite3 -y 
wget https://github.com/lxdware/lxd-dashboard/archive/refs/tags/v3.7.0.tar.gz
tar -xzf v3.7.0.tar.gz

cp -a lxd-dashboard-3.7.0/default /etc/nginx/sites-available/ && \
cp -a lxd-dashboard-3.7.0/lxd-dashboard /var/www/html/

mkdir -p /var/lxdware/data/sqlite && \
mkdir -p /var/lxdware/data/lxd && \
mkdir -p /var/lxdware/backups

chown -R www-data:www-data /var/lxdware/ && \
chown -R www-data:www-data /var/www/html

nano /etc/nginx/sites-enabled/default 

    #fastcgi_pass unix:/run/php/php7.4-fpm.sock;
    fastcgi_pass unix:/run/php/php8.1-fpm.sock;
    
systemctl restart nginx

Thanks for great app!

Edit, oh, now i see that this is mentioned in the Ubuntu 22.04 guide, my apologies.
Still, a mention could maybe be added to the LXC container guide, to save users some time debugging.

Feel free to remove this issue if it seems unnecessary.
