CRON jobs not running anymore after php module installation

NextcloudPi version: 1.52.2
Nextcloud version (eg, 20.0.5): 26.0.3.2
Operating system and version (eg, Ubuntu 20.04): Debian GNU/Linux 11.7 (bullseye)
Apache or nginx version (eg, Apache 2.4.25): Apache 2.4.56
PHP version (eg, 7.4): 8.1.21

Yesterday I tried to address a warning of my new NextcloutPi installation on my Raspberry Pi Model 3:

The PHP module "imagick" is not enabled although the theming app is. For favicon generation to work correctly, you need to install and enable this module.

Following the advice in some forum discussion, I installed php-imagick and php-apcu via apt-get.
Today I noticed an error about background jobs not working anymore:

Last background job execution ran 23 hours ago. Something seems wrong. Check the background job settings.

sudo -u www-data crontab -l
returns
*/5 * * * * php -f /var/www/nextcloud/cron.php
but if I try to run the CRON job manually with
sudo -u www-data php -f /var/www/nextcloud/cron.php
I get the following error:

Doctrine\DBAL\Exception: Failed to connect to the database: An exception occurred in the driver: could not find driver in /var/www/nextcloud/lib/private/DB/Connection.php:140

Also I noticed there are two php directories
/etc/php/8.1/ AND /etc/php/8.2/

php -m returns

Looks like I have messed up the php installation, correct?
Please tell me there is a way to fix this without having to start from scratch with a clean NextcloudPi image! :scream:

Thank you for your help!

Decide which php version you want to use.
I would advise to take 8.2 but if you prefere 8.1, its totaly OK.

Look for installed php-packages:

dpkg -l | awk '/^ii.*php/ {print $2}'

Look what php is used by your apache webserver with this command:

apachectl -tD DUMP_INCLUDES | sed -n '/php.*conf/ s#.*/\([^/]*\)\.conf#\1#p'

If you want to remove e.g. all php8.1 packages:

sudo apt-get remove --purge php8.1*

And if you want to install new pecl packages, don’t use apt instal php-<pecl> but php8.2-<pecl> instead

ernolf, you are a lifesaver, that did the trick!

I checked what php packages were installed with the dpkg-line you suggested and what php version my apache was using with your apachectl-line.
I then decided to keep php 8.1, because that is what apache was using originally, and I removed all php8.2* packages like you suggested.

After an apache restart everything seems to be working again :partying_face:

Now I will try to install imagick again, specifying the php version this time.

Thank you so much! I am so happy I do not have to setup the whole system again :sweat_smile:
