On my Ubuntu Server 16.04.1 I am not able to run two jobs in cron. My crontab looks like this
root@vps:~# crontab -l
# 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
0 6 * * * /usr/sbin/apachectl -k graceful
0 3 * * * /usr/bin/letsencrypt renew
I also tried relative paths with just apachectl and letsencrypt, but nothing has changed.
When I run the commands directly, it's ok and everything works. But the jobs from cron are not executed.
What can be wrong please?
/var/log/syslog
around 6:00 and 3:00 and see if these jobs have actually run.sudo journalctl -u cron.service --since "03:00" --until "06:05"
