I’ve installed Spotweb on my Raspberry Pi 3 running OSMC as per the guide on HTPC Guides. Most of the process went well (Spotweb was installed, I can retrieve headers and Sonarr and Couchpotato can pull NZBS from it) but I can’t get the cronjob to get to work for the life of me. As I am pretty much a beginner when it comes to Linux, I am not sure what to look for to troubleshoot the issue. I have tried:
- making sure cron is installed (it is),
- restarting crontab,
- checking a simple reboot cronjob (*/2 * * * * /sbin/reboot) works (it did)
- using full paths (see output below),
- adding ‘root’ and ‘www-data’ as users at the beginning of the cronjob (before ‘php’),
- including an empty line at the end of the job and
- removing the logging part of the cronjob. However, retrieve.php is never run and the log as specified in the job is not created.
This is the current output of crontab -l:
*/5 * * * * /usr/bin/php /var/www/spotweb/retrieve.php > /var/www/spotweb/retrieve.log (I can’t copy the empty line at the end of the job, but it’s there.) It’s on 5 minutes for testing purposes; this will become */30 when the job finally works.
The output of sudo service crontab status:

The job is started but doesn’t actually fire and no log file is created in Spotweb’s directory. Is it related to the ‘No MTA installed’ message? Maybe a user permission issue? I’ll be happy to post more output if necessary. Thanks in advance for the help!
