Hi Folks,
I’m having an rather strange issue that I can’t get /var/www/nextcloud.cron.php executed correctly.
I first did the standard stuff:
crontab -u www-data -e
*/15 * * * * /usr/bin/php -f /var/www/nextcloud/cron.php
that did not give me a working cronjob.
Then I did it manually:
sudo -i
sudo -u www-data php /var/www/html/nextcloud/cron.php
and cron seems to be executed; correct represented as well at the basic settings ‘background jobs’ the cron job icon turned happily green.
I then added as well the job to crontab itself using:
*/15 * * * * www-data /usr/bin/php -f /var/www/nextcloud/cron.php >/dev/null 2>&1
still cron is not executed for cron.php
What I see in this syslog is this:
Aug 21 19:15:01 nextcloud CRON[2090]: (www-data) CMD (/usr/bin/php -f /var/www/nextcloud/cron.php)
Aug 21 19:15:01 nextcloud CRON[2091]: (root) CMD (www-data /usr/bin/php -f /var/www/nextcloud/cron.php >/dev/null 2>&1)

Aug 21 19:45:35 nextcloud crontab[2167]: (root) END EDIT (www-data)
Am I forgetting something here or am I overlooking something as I really now got lost 
thnx for helping out where anyone could…
edit: as I now had 2 cronjobs at the same time I moved back to only using the one from:
crontab -u www-data -e
I even added my path in there as well.
see now that syslog shows a single crontab output:
Aug 21 21:32:07 nextcloud crontab[3650]: (root) BEGIN EDIT (www-data)
Aug 21 21:32:21 nextcloud crontab[3650]: (root) REPLACE (www-data)

Aug 21 21:37:42 nextcloud crontab[3840]: (root) BEGIN EDIT (www-data)
however it still does not work and the cronlog.txt does not show any output
any guidance anyone?
