Question Fresh Plesk install on EC2 fails at the finish line, failed 'crontabmng' 'set' 'psaadm'

[Paul Larson]

Server operating system version

Ubuntu 22.04

Plesk version and microupdate number

18

The EC2 is using Ubuntu 20.04 LTS. Everything seems fine in the CLI installer until the very end, when errors about psaadm and crontab emerge:

Is the problem in the WP TOOKIT extension package? I recently had the same problem and haven't been able to solve it, I haven't had time to research to solve it, does anyone or an expert have any advice for this situation? Thank you

 

[Kaspar@Plesk]

Did you install or configured anything else on the server prior to installing Plesk?

 

[Paul Larson]

It's moot, now. I just gave up and installed a Plesk-supplied EC2 image.

But no, I didn't install anything special.
