Internal error after update, no log

[Ykonoclast]

Nextcloud version (eg, 20.0.5): 20.0.14
Operating system and version (eg, Ubuntu 20.04): Debian 11
Apache or nginx version (eg, Apache 2.4.25): nginx 1.1.18
PHP version (eg, 7.4): 7.3 and 7.4

The issue you are facing: I have a very old server (I’m planning to completely overhaul it but I need it to hold on for a few more months as I don’t have any time to do it right now) running Nextcloud 20.0.14 with nginx 1.1.18.

Everything was working well under Debian 10, I just updated it to Debain 11 and then I encountered the “internal error” page which directed me to consult the log file.
The problem is the log file is empty, I tried changing the log level parameter in config.php to no avail.

I realized that going to Debian 11 removed php7.3, that I was using, even though the 7.4 replacement had the same modules installed and the socket was the same for nginx.

I tried to re-install all the 7.3 modules (using the sury repo) and expected everything to go back to normal as my old config files were all still there, but I still get the internal error page.

That particular server had been running for seven years (I used the command line updater several times without any problem). But without any log I’m a bit at a loss and would be thankful for any kind of help.

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

The output of your config.php file in /path/to/nextcloud (make sure you remove any identifiable information!):

The output of your Apache/nginx/system log in /var/log/____:

If using php7.4

And nothing if using php7.3

I am not particularly technical, I set up this server seven years ago and am actually a bit rusted on exactly how I did it so I would be grateful for any kind of help.

First change back to the php version from Debian 11 (PHP 7.4). Please check all other php stuff is uninstalled:
dpkg -l |grep -i php

Execute on command line. Maybe you get further informations, maybe not:
sudo -u www-data php /path/to/nextcloud/index.php

Maybe there is a PHP setting problem. Read this installation guide. Mabe you find some facts of your problem e.g. missing php packages or missing configurations.

and the socket was the same for nginx.

Do I misunderstand that?

The socket for 7.3 is (was):

• /run/php/php7.3-fpm.sock

while the socket for 7.4 is

• /run/php/php7.4-fpm.sock

Did you adapt the "/etc/nginx/sites-available/nextcloud" to listen to the new socket accordingly?

As for sudo -u www-data php /path/to/nextcloud/index.php this is getting interesting as I get :

This version of Nextcloud is not compatible with > PHP 7.4.<br/>You are currently running 8.3.3-1+0~20240216.17+debian11~1.gbp87e37b.

Why would it say I’m running 8.3.3?

For, so as to answer Ernolf : I was using the /etc/alternatives socket, which was a symlink to /run/php/php7.3-fpm.sock and got updated to /run/php/php7.4-fpm.sock with the update.

Naturally I then tested with both the exact absolute paths. I currently have /run/php/php7.4-fpm.sock in the nginx conf, as devnull suggested. No idea why 8.3.3 is used.

No idea why 8.3.3 is used

Thats very simple, because you called it from the commandline which relies on the cli SAPI of php. That one uses php 8.3:

readlink -f $(which php)

You should realy remove all not used php packages:

sudo apt-get purge *php7.0* *php8.3*

then you should get rid of all unnecessary dependency packages.

You can install and run the php-updater script, it will give you comprehensive information about which package is a dependency package and which one is not.
It comes with an extensive help guide. Read it carefully, then - I hope - everything will be clear to you.

[devnull]

While you’re at it, you should delete all “rc” packages. Only the configuration is still available here. This at least increases the overview. However, you should only do this if you really no longer need the configurations for these orphaned packages.

apt-get remove --purge $(dpkg -l | awk '/^rc/{print $2}')

cli vs. web:
Yes there is a difference and my command php index.php can show the error or not.

[Ykonoclast]

Ok, so I re-executed php index.php with the real php7.4 command, here is the result :

Sorry the cli way does not help. Please read this installation guide and check if all packages are installed and maybe check configurations for nginx and php.

Then check your logs in /var/log/, logs for nginx and Nextcloud log /path/to/nextcloud/data/nextcloud.log and post more infos.

The requirement for Nextcloud 20 seems ok.

Do you really want to upgrade 8 times to Nextcloud 28? Maybe you can install Nextcloud 28 better. You can include your old files in your new Nextcloud. But you will lose all other structures.

The plan is to completely rebuild this server on a new machine and a much updated software base (new nginx, fresh nextcloud install etc.) in a few months.

I just need this one to hold on just a bit longer (and I sincerely regret making this Debian update now…).

Still nothing in nextcloud log. Nginx access log has nothing either, error log (with php 7.4) is still the same :

2024/02/21 15:47:16 [error] 31694#31694: *5 FastCGI sent in stderr: "PHP message: PHP Fatal error:  Uncaught Error: Class 'OCA\DAV\Connector\Sabre\ExceptionLoggerPlugin' not found in /var/www/spacedock/nextcloud/remote.php:61

I checked packages installation, I didn’t have libmagickcore-dev, I installed it but the situation is unchanged.

I didn’t modify my nginx config (appart from the php socket), it was working this very morning when I did my last sync before starting the Debian update. I hadn’t realize this would break Nextcloud so thoroughly (I did it before, I just had to change the socket, make sure modules were installed and update php config and I was good to go).

Did you follow my advice from yesterday to remove unneeded php versions and all dependency packages?

Apparently not. You have three fpm sockets up and listening. That is like asking for trouble.

Did you read the help from the php-updater script?

Did you follow the steps about how to switch the alternatives?

If you do not (want) to remove unneeded versions then you should at least stop and deactivate the unused services:

sydo systemctl stop php7.3-fpm
sudo systemctl disable php7.3-fpm
sydo systemctl stop php8.3-fpm
sudo systemctl disable php8.3-fpm

that wil prevent the php7.3-fpm and php8.3-fpm from starting automaticaly (and consuming resources)

In a next step, you should switch all php related alternatives to “Manually” 7.4:

for linkgroup in $(ls /var/lib/dpkg/alternatives/ | grep -E "ph(ar|p)"); do sudo update-alternatives --config $linkgroup; done

And of course you have to restart your webserver and php-fpm service after made changes:

sudo systemctl restart nginx php7.4-fpm

At this stage I prefer not to delete alternatives php versions, as it is still possible I can make Nextcloud work with another version than 7.4 and performance is not an issue while the server is not even running.

grep -R “fpm” /etc/nginx/sites-enabled gives :

/etc/nginx/sites-enabled/default:	#	# With php-fpm (or other unix sockets):
/etc/nginx/sites-enabled/default:	#	fastcgi_pass unix:/run/php/php7.4-fpm.sock;

I read the php-updater help. While it is a terrific tool (congrats, will definitely use it in the future), I had already modified config files for php 7.4 by hand and changed the socket at this stage (and php7.3 had already been uninstalled by the Debian update… and re-installed afterwards by myself with the sury repo), which limited its pertainability to my situation.

At this stage I will probably completely reinstall Nextcloud, probably using a version supporting php 8.3.3, the latest on my install. I’d rather not have to do that work, but it seems increasingly unlikely that the current install can be recovered. All because of an update, that is an unfortunate fragility.

[Ykonoclast]

I compromised and reinstalled version 25 to use the already configured php7.4.

It is working right now, I lost optimisations but it is sufficient for the few months this machine has left.

I kept the former install in a separate location in any case, but we’ll probably never know what went wrong with it.

Anyway, thanks everyone for taking time to help.
