Re: problem with cron on Kubuntu 22.04
THANK YOU Your guess was wrong, but sudo systemctl status cron (which I did not think of before) helped me find the problem. The service WAS running, but the output of that command showed that the owner of /etc/crontab was not root. A stupid mistake on my part - I copied the file from another computer and did not change the owner. But I would not have found the error without your help, so again - THANK YOU !

Re: problem with cron on Kubuntu 22.04
If I had to hazard a guess, it has something to do with systemd (the usual suspect) What does `|sudo systemctl status cron` return? If that shows the service being disabled or stopped, you'll of course need to run `||sudo systemctl enable cron` to get it going at every boot and |`|sudo systemctl start cron||` to start it immediately |On 07-Feb-24 11:23, Shlomo Solomon wrote: No - that did not change anything and, in any case, as I wrote, that exact line (including root) works on another Kubuntu 22.04 machine.

No - that did not change anything and, in any case, as I wrote, that exact line (including root) works on another Kubuntu 22.04 machine.

problem with cron on Kubuntu 22.04
Sorry if this is a bit long, but I wanted to give as much information as I could and hope someone can help. On a new installation of Kubuntu 22.04, cron jobs are not running and this is driving me crazy. The cron daemon is running shoshana@shoshana:~/Desktop$ pgrep cron 827 I thought there might be a problem with a specific job so I created the following simple script (which DOES work). shoshana@shoshana:~/Desktop$ cat tstrun #!/usr/bin/sh cd /home/shoshana/Desktop echo "" >> tst.txt If I do: cd /home/shoshana/Desktop ./tstrun the script works and I see in tst.txt I then deleted ALL jobs in crontab and added only the following to /etc/crontab */1 * * * * root /home/shoshana/Desktop/tstrun Nothing happens - nothing written in tst.txt I tried: sudo grep CRON /var/log/syslog and got no output I changed the script to: #!/usr/bin/sh echo "test echo from tstrun" cd /home/shoshana/Desktop echo "" >> tst.txt and changed the crontab line to: */1 * * * * root /home/shoshana/Desktop/tstrun >> /home/shoshana/Desktop/tstrun-log.txt still no output in tst.txt and also no output in /home/shoshana/Desktop/tstrun-log.txt And as expected, if I do: ./tstrun >> tstrun-log.txt I see the expected output in both files I also tried: shoshana@shoshana:~/Desktop$ sudo service cron stop shoshana@shoshana:~/Desktop$ sudo service cron start shoshana@shoshana:~/Desktop$ pgrep cron 3377 AND shoshana@shoshana:~/Desktop$ sudo systemctl stop cron shoshana@shoshana:~/Desktop$ sudo systemctl start cron shoshana@shoshana:~/Desktop$ pgrep cron 3413 But still no change.
