PHP version (eg, 7.1): PHP 7.1

The issue you are facing:
So whenever I try to open Nextcloud, I get an internal server error thrown. I have no idea what causes it. I have tried going in via localhost, 192.168.1.75 (the static IP that I have set for the machine running the instance) and the dynamic dns (which I haven’t set up right anyway, so idk why I was trying to go through that.) I’ve tried restarting the system, but it hasn’t worked. I’ve googled round but can’t find anything (hence why I’m creating a new topic) - can anyone make some sense out of these logs please?

Cheers!

Is this the first time you’ve seen this error? (Y/N): No

Steps to replicate it:

Open 192.168.1.75 (the static IP that has been set for the machine hosting the install) in Firefox

Expected Result: Opens to the login screen
Actual Result: Displays the following:

Internal Server Error

for me, this look like your server is missing dependencies and/or is miss-configured.

recheck them using apt-get

a good apache2 install:
apt-get install apache2 apache2-mpm-prefork apache2-prefork-dev libapr1-dev libaprutil1-dev libfcgi-dev libssl-dev zlib1g-dev libcurl4-openssl-dev

tune and check your conf by accessing your http://localhost and by using apache2 -v

optional: php manipulation images software:
apt-get install imagemagick libmagickwand-dev

php-packages:
apt-get install php7.1-fpm php7.1 php7.1-xml php7.1 php7.1-cgi php7.1-cli php7.1-gd php7.1-curl php7.1-zip php7.1-mysql php7.1-mbstring

if mysql use then
apt-get install mysql-server mysql-common libmysqlclient-dev mysql-client

after that, create the mysql user and database

When this is done and working, you can continue with nextcloud and recheck logs ( system log, not nextcloud log as error 500 is apache error an/or subsystem error

It shouldn’t be missing dependencies. As you may have picked up from the paths I modified, I installed Nextcloud using the Ubuntu Snap. Also it might be worth saying that I managed to successfully set up and log in before this happened. Any more ideas?

Your config file trusted domains is missing commas after the quote after each element. Make it like the others.

Yours:

‘trusted_domains’ =>
array (
0 => ‘localhost’,
1 => ‘[REDACTED].serveftp.com’
2 => ‘192.168.1.75’
3 => ‘[REDACTED]’
),

Should be:

‘trusted_domains’ =>
array (
0 => ‘localhost’,
1 => ‘[REDACTED].serveftp.com’,
2 => ‘192.168.1.75’,
3 => ‘[REDACTED]’,
),

That last comma added is optional but not a bad idea in case you add a new one, and don’t remember to add it in for the previous line.

I know some time has passed with this, but I just upgraded a server from Ubuntu 16.04 to 18.04 and we’re seeing the same issue. Were you ever able to solve this?

XMX · May 30, 2019, 5:28pm

Ive been strugling with the very same message after an upgrade attempt to latest stable.

fwolfst · January 23, 2020, 8:26am

Such a message can be shown e.g. if your database is down.
