Hello,
I came into today seeing our LibreNMS was complaining about PHP dependencies being on 8.2 and we were running Ubuntu 20.xx.
I upgraded to Ubuntu 22 along with PHP 8.3.16.
After the upgrade I was still seeing the PHP dependencies message on the GUI. I used this guide;
along with this to assist in my issues;
At step 7 of the first URL the PHP service is failing to start. I verified sock matches in Nginx and Librenms Config.

Now on the GUI I am getting a 502 Bad Gateway error
librenms.conf
Start a new pool named ‘librenms’.
; the variable $pool can be used in any directive and will be replaced by the
; pool name (‘www’ here)
[librenms]
; Per pool prefix
; It only applies on the following directives:
; - ‘access.log’
; - ‘slowlog’
; - ‘listen’ (unixsocket)
; - ‘chroot’
; - ‘chdir’
; - ‘php_values’
; - ‘php_admin_values’
; When not set, the global prefix (or /usr) applies instead.
; Note: This directive can also be relative to the global prefix.
; Default Value: none
;prefix = /path/to/pools/$pool
; Unix user/group of the child processes. This can be used only if the master
; process running user is root. It is set after the child process is created.
; The user and group can be specified either by their name or by their numeric
; IDs.
; Note: If the user is root, the executable needs to be started with
; --allow-to-run-as-root option to work.
; Default Values: The user is set to master process running user by default.
; If the group is not set, the user’s group is used.

; The address on which to accept FastCGI requests.
; Valid syntaxes are:
; ‘ip.add.re.ss:port’ - to listen on a TCP socket to a specific IPv4 address on
; a specific port;
; ‘[ip:6:addr:ess]:port’ - to listen on a TCP socket to a specific IPv6 address on
; a specific port;
; ‘port’ - to listen on a TCP socket to all addresses
; (IPv6 and IPv4-mapped) on a specific port;
; ‘/path/to/unix/socket’ - to listen on a unix socket.
; Note: This value is mandatory.
listen = fastcgi_pass unix:/run/php/php8.3-fpm.sock;
; Set listen(2) backlog.
; Default Value: 511 (-1 on Linux, FreeBSD and OpenBSD)
;listen.backlog = 511
; Set permissions for unix socket, if one is used. In Linux, read/write
; permissions must be set in order to allow connections from a web server. Many
; BSD-derived systems allow connections regardless of permissions. The owner
; and group can be specified either by name or by their numeric IDs.
; Default Values: Owner is set to the master process running user. If the group
; is not set, the owner’s group is used. Mode is set to 0660.
listen.owner = librenms
listen.group = librenms
;listen.mode = 0660

; List of addresses (IPv4/IPv6) of FastCGI clients which are allowed to connect.
; Equivalent to the FCGI_WEB_SERVER_ADDRS environment variable in the original
; PHP FCGI (5.2.2+). Makes sense only with a tcp listening socket. Each address
; must be separated by a comma. If this value is left blank, connections will be
; accepted from any ip address.

Any assistance would be greatly appreciated.
