I had a weird issue with crontab today.
If I editted the crontab while logged in as root, it did not work.
$# whoami root $# crontab -e ((( make edits ))) crontab: installing new crontab
But the changes did not work.
$# exit $ whoami ubuntu sudo crontab -e ((( make edits ))) crontab: installing new crontab
And the changes work just fine.
One clear difference was user ubuntu was using nano to edit, while user root was using emacs… But seems weird if that would make a difference.
The same cronfile was edited both times.
Anyway, I got it working by
sudo crontab -e instead of having root
