problem with cron on Kubuntu 22.04
by Shlomo Solomon 09 Feb '24

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 "aaaa" >> tst.txt If I do: cd /home/shoshana/Desktop ./tstrun the script works and I see aaaa 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 "aaaa" >> 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. And just to be clear, on a different machine (also Kubuntu 22.04) all the above DOES work - output to both files and if I do: sudo grep CRON /var/log/syslog I get: Feb 7 17:13:01 solomon-laptop CRON[16619]: (root) CMD (/home/solomon/Desktop/tstrun) -- Shlomo Solomon http://the-solomons.net Claws Mail 3.17.5 - KDE Plasma 5.18.5 - Kubuntu 20.04
