Install ssh-cron by entering the following commands in the terminal:
sudo apt update sudo apt install ssh-cron
Description:
cron daemon allowing ssh keys with passphrases to be used
ssh-cron acts like cron, but utilizes ssh-agent to obtain ssh key passphrases. Thus it allows scheduled commands to run on remote systems without requiring the ssh key passphrase to be stored in a clear-text file, or resorting to ssh keys without passphrases.
