I know this question has been answered many time. I refereed heemayls answer in this post to set up the cron job. However, it is not working. Any idea on what is going wrong?
*/1 * * * * /usr/bin/env python3 /home/me/DownloadImages1.0.py
The following is the output of
# Edit this file to introduce tasks to be run by cron. # # Each task to run has to be defined through a single line # indicating with different fields when the task will be run # and what command to run for the task # # To define the time you can provide concrete values for # minute (m), hour (h), day of month (dom), month (mon), # and day of week (dow) or use '*' in these fields (for 'any').# # Notice that tasks will be started based on the cron's system # daemon's notion of time and timezones. # # Output of the crontab jobs (including errors) is sent through # email to the user the crontab file belongs to (unless redirected). # # For example, you can run a backup of all your user accounts # at 5 a.m every week with: # 0 5 * * 1 tar -zcf /var/backups/home.tgz /home/ # # For more information see the manual pages of crontab(5) and cron(8) # # m h dom mon dow command */1 * * * * /usr/bin/env python3 /home/me/DownloadImages1.0.py

*/1has no much sense. It means, every minute, where the rest of the integer division between that minute and one = zero. This always happens because everything can be divided by one without rest. You may have copy-pasted that from another script and then adapted. You can safetly replace
*that it's its exact definition: run every minute. This does not solve your problem but simplify your answer. Having said that, your problem is in your specific Python script and you should read your crontab error logs. We can't help you without further information.
