GitMate.io thinks possibly related issues are #10748 (Background jobs fails (cron)), #8759 (Run cleanup of old upload parts in background job), #4179 (Cron jobs not running, and logs filled with "preg_match(): Unknown modifier '/' at..."), #7336 (Error while running background job (Doctrine\DBAL\Exception\DriverException):), and #10658 (Error while running background job (OCP\AutoloadNot AllowedException): Autoload path not allowed).

Exactly the same issue for me. Any idea to solve it?

Does 'cron.php' run OK without errors from the terminal?
cd /path/to/nextcloud
php cron.php

Type which php to obtain the path of the php command that is executed from the terminal. Is it /usr/local/bin/php perhaps?

Try these cron tasks;
* * * * * set > /tmp/vars.txt
* * * * * which php > /tmp/php.txt; php -v >>php.txt

Now from terminal
cat /tmp/vars.txt | grep PATH
and
cat /tmp/php.txt
Is the path to the terminal php command included in the PATH variable of the cron job? Does cron run the same php?
cron jobs do not run /etc/bashrc, /etc/profile, ~/.bashrc or ~/.bash_profile before execution and the cron.php script probably looks for files relative to the current directory when it was executed.

Try;
for C in $(find / -maxdepth 4 -type f -name php 2>/dev/null); do echo $C; $C -v; echo ; done

This lists three different versions of php on my shared host so cron could be calling a different version/build of php to the one used in your terminal or nextcloud site.

0,15,30,45 * * * * cd /path/to/nextcloud; /path/to/terminal/phpcommand/php -f /path/to/nextcloud/cron.php
should be the correct way to run cron.php if it functions as expected when run manually from the terminal after a cd to the nextcloud folder.

Also consider something that does not need to know the nextcloud foldername;
'0,15,30,45 * * * * JOB=$(find ~/ -name -maxdepth 4 cron.php -print -quit); cd $(dirname $JOB); /path/to/working/php -f $JOB
or one cron task for multiple instances of nextcloud on same server.
'0,15,30,45 * * * * for JOB in $(find ~/ -maxdepth 4 -name cron.php | grep -v .trash); do cd $(dirname $JOB); /path/to/working/php -f $JOB; done

Thinking ahead, once your nextcloud instance is using cron correctly, it might be a good idea to remember to remove/disable the task before performing any future upgrades in case it runs during the upgrade. I make a clone of my nextcloud and database to test upgrades nowadays as there is always the possibility of a backup not restoring. It might also be wise to disable any automatic update features in whatever auto installer you used such as softaculous or installatron. Personally I have found installing sfuff fthis way problematic and do not use anymore and they arent usually up-to-date versions. Better to create DB and DB user yourself, wget the latest package and extract from the terminal.

I think some people having this error may have a different version of php set for /etc/alternatives than is enabled in apache, but I can't add answers to the following questions due to the site being readonly:

• https://help.nextcloud.com/t/doctrine-dbal-dbalexception-failed-to-connect-to-the-database-an-exception-occured/41109
• https://help.nextcloud.com/t/failed-to-connect-to-the-database-cron-background-jobs/38368

I fixed the error by making sure /etc/alternatives and apache were running the same version of php (this makes sure all the same modules that correctly run nextcloud also are available to /usr/bin/php:

1. Get your loaded php module version:

sudo apache2ctl -M | grep php

2. Get your /usr/bin/php version:

/usr/bin/php --version

If they don't match, update-alternatives, replacing X.X with the version found in (2) above:

sudo update-alternatives --set php /usr/bin/phpX.X

(Ubuntu 18.04 Bionic Beaver)

@nix155 @nextcloud-bot Why was #7336 closed without a reason for closing provided? My solution can resolve "PHP Fatal error: Uncaught Doctrine\DBAL\DBALException: Failed to connect to the database: An exception occured in driver: could not find driver in ..." in the case that the problem does not lie in Nextcloud like in my case.

OPTIONAL: Change php version for everything (do not do the method below unless you know what you're doing, otherwise change 7.1 in the following back to X.X found above:

ver=7.2
sudo update-alternatives --set php /usr/bin/php$ver
echo "If you use PostgreSQL as your backend, also run:"
echo "sudo apt install php$ver-pgsql"
sudo apt install php$ver-mysql
sudo a2dismod php7.3
sudo a2dismod php7.2
sudo a2dismod php7.1
# AND any other versions you may have enabled,
# or next line will have error saying phpX.X already enabled!
sudo a2enmod php$ver

# next 9 lines are from https://docs.nextcloud.com/server/14/admin_manual/installation/source_installation.html#ubuntu-installation-label
sudo apt install apache2 mariadb-server libapache2-mod-php$ver
sudo apt install php$ver-gd php$ver-json php$ver-mysql php$ver-curl php$ver-mbstring
sudo apt install php$ver-intl php-imagick php$ver-xml php$ver-zip
sudo a2enmod rewrite
sudo a2enmod headers
sudo a2enmod env
sudo a2enmod dir
sudo a2enmod mime
sudo a2enmod ssl


# sudo apt install php$ver-sqlite3
echo "also run: sudo apt -y install php$ver-pgsql # as needed if you use that for Nextcloud"
# sudo apt install php$ver-mysql
# sudo apt install php$ver-pgsql
sudo systemctl restart apache2
