Bench init frappe-bench error on Ubuntu 22 LTS

1

Hello everyone!

I am following the instructions on this page: Installation

When I get to the second to last command: bench init frappe-bench

I see the error:

 DONE  Total Build Time: 20.132s

ERROR: There was a problem while creating frappe-bench

Could anyone enlighten me as to what might be wrong?

Thank you!

You don’t have crontab installed, which is a system dependency? if you don’t want automatic backups, there should be a flag to do so - check bench init --help

You are right, thank you!

Ubuntu 22 does not have cron installed by default :crazy_face:. I just had to run sudo apt install cron
