Some or all of the below information will be requested if it isn’t supplied; for fastest response please provide as much as you can

Nextcloud version (eg, 20.0.5): 24.0.7
Operating system and version (eg, Ubuntu 20.04): Ubuntu 20.04
Apache or nginx version (eg, Apache 2.4.25): Apache 2.4.41-4ubuntu3.12
PHP version (eg, 7.4): 7.4.33

The issue you are facing:
Since updating my Ubuntu server (apt upgrade) I get:


The server encountered an internal error and was unable to complete your request.
Please contact the server administrator if this error reappears multiple times, please include the technical details below in your report.
More details can be found in the server log.

Is this the first time you’ve seen this error? (Y/N): Y

Steps to replicate it:

navigate to my nextcloud url

I am able to reach the Apache2 default page with the IP address, and can get php.info with IP address and /info.php.

No errors appear in the apache2 logs when refreshing either the IP address or the URL.

I get the entry:

166.62.236.50 - - [22/Nov/2022:19:14:02 +0000] "GET /index.php/apps/dashboard/ HTTP/1.1" 500 1072 "-" "Mozilla/5.0 (X11; Linux x86_64; rv:107.0) Gecko/20100101 Firefox/107.0"

in the nextcloud.access file when I refresh the URL.

I see error messages related to Redis, but I have it installed to this version:

Redis server v=5.0.7 sha=00000000:0 malloc=jemalloc-5.2.1 bits=64 build=66bd629f924ac924

When I navigate to https://hub.cnsp-rcps.ca/staus.php, as indicated in the error:

'Primary script unknown', referer: https://hub.cnsp-rcps.ca/staus.php

I get a page that simply says “File not found.”

I have an image of the working instance from about a year ago, but I am hoping to get this working once again before attempting the nuclear option and rolling back to that image.

Thanks in advance for any help.

Michael2105 · November 23, 2022, 5:55am

Hi,

Config variable ${APACHE_RUN_DIR} is not defined

Your problem is that you haven’t set a proper hostname inside apache2.conf
https://stackoverflow.com/questions/72105163/apache-http-server-config-variable-is-not-defined-error-how-to-solve

DefaultRuntimeDir must be a valid directory

Du you have /var/run/apache2 directory? If not create it.

‘Primary script unknown’, referer: https://hub.cnsp-rcps.ca/staus.php

Shouldn’t it be …staTus.php ?

I decided to move to nginx as the web server, as I was getting nowhere trying to fix the apache2.conf, as suggested above.

Navigating to my IP address gets me to the Welcome to Nginx page, so I know that is working.

I created a file called phptest.php in the webroot (/usr/share/nginx/html) containing:
<?php phpinfo(); ?>

Navigating to the ip/phptest.php get me a page with:

404 Not Found

nginx/1.18.0 (Ubuntu)

Running
sudo -u www-data php /var/www/nextcloud/occ

Gets me the following output:

} catch (PDOException $e) {
    echo 'Connection failed: ' . $e->getMessage() . "\n";
}

?>

Gets me this output:
Connection failed: could not find driver

So, I am thinking that this is a general php problem, not only related to Nextcloud, but I can’t pinpoint where the issue is.

I have removed all versions of php except for 8.1 on my system. I am wondering if that might have broken things?

This is the list of php modules (php -m):

I can’t find anything that looks fishy to me, but I am certainly no expert.

If you switched from apache to nginx you will have to move your nextcloud installation directory to the webroot of nginx as well.
Apache mostly uses /var/www/html…
nginx uses /usr/share/nginx/html

So how shall nginx find your nextcloud installation if it is still located under the apache path?

For the database connection - it seems your php installation is missing the corresponding php module for your database.

From the guide that I used to setup in the first place I was instructed to install nextcloud to /var/www/.

So this is what I have:

ubuntu@cnsp-hub-server:~$ ls /var/www
html  nextcloud

The same guide, but for using nginx, also says to install to /var/www/.

The directories you mention look like this for me:

ubuntu@cnsp-hub-server:~$ ls /var/www/html
index.nginx-debian.html  info.php

and

ubuntu@cnsp-hub-server:~$ ls /usr/share/nginx/html
index.html  phptest.php

I have this set up as /etc/nginx/conf.d/nextcloud.conf:

server {
    listen 80;
    listen [::]:80;
    server_name nextcloud.example.com;

    # Add headers to serve security related headers

    add_header X-Frame-Options "SAMEORIGIN";

    }

    # Adding the cache control header for js and css files

        access_log off;
   }
}

I have done:

sudo chown www-data:www-data /var/www/nextcloud/ -R

and nginx seems to be running fine:

ubuntu@cnsp-hub-server:~$ sudo nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

I installed the following php modules:

imagemagick php-imagick php8.1-common php8.1-pgsql php8.1-fpm php8.1-gd php8.1-curl php8.1-imagick php8.1-zip php8.1-xml php8.1-mbstring php8.1-bz2 php8.1-intl php8.1-bcmath php8.1-gmp

and it seems I have only php8.1 installed:

ubuntu@cnsp-hub-server:~$ ls /etc/php
8.1

ubuntu@cnsp-hub-server:~$ php --version
PHP 8.1.2-1ubuntu2.9 (cli) (built: Oct 19 2022 14:58:09) (NTS)
Copyright (c) The PHP Group
Zend Engine v4.1.2, Copyright (c) Zend Technologies
    with Zend OPcache v8.1.2-1ubuntu2.9, Copyright (c), by Zend Technologies

BUT, when I check for phpinfo by adding /phptest.php to the ip address I get

502 Bad Gateway

the same occurs when i try info.php, which I placed in /var/www/html

Directly going to the IP address gets me to the Welcome to Nginx page.

I am really flailing around with this right now, and can’t make heads or tails of what is causing this problem.

more output:

ubuntu@cnsp-hub-server:/var/www/nextcloud$ sudo -u www-data php occ

Well I gave up.

I was able to recover my system with a snapshot image of the instance from before the update and issues.

Now I have a separate issue given that the image is of an instance of Nextcloud 22.2.3 and it refuses to update!
