Sorry. I missed a dash

Progress. But now I get this when trying to run the installer:

Server Error​

500

check your system logs. /var/log/plesk/panel.log, maybe /var/log/messages

Remember this is installed via the browser /installer/install.cgi I saw noting in the logs that appeared relevant.

DadaMail doesn't install on Ubuntu 20.04 and appears it doesn't like MySQL 8.
I found this out after upgrading working version of DadaMail on 18.04 and upgrading. Failed.
