just passing this along. Just got done with my CentOS 8-stream Perfect server installation (thank you for the instructions!) and at the end of the ISPConfig installation, the following appeared: Configuring Postfix Configuring Dovecot Configuring Mailman Configuring Spamassassin Configuring Amavisd Configuring Getmail Configuring BIND Configuring Pureftpd Configuring Apache Configuring vlogger Configuring Apps vhost Configuring Jailkit Configuring Database Updating ISPConfig ISPConfig Port [8080]: Create new ISPConfig SSL certificate (yes,no) [no]: /usr/bin/which: no acme.sh in (/usr/local/ispconfig/server/scripts) Reconfigure Crontab? (yes,no) [yes]: Updating Crontab Restarting services ... Failed to restart clamd.amavisd.service: Unit clamd.amavisd.service not found. Update finished. the "Failed to restart" happens after the initial install, and update, and an update (forced, nightly) as well. it looks like it should be 2 commands, not 1, but that's a guess on my part. (is the no acme.sh message an issue also, or just output from trying to figure out where acme is?)
i think it's a typo in the script - looks like it's missing the "@" sign. this is the instruction from the Perfect server instructions for clamd/spamassasin installation: systemctl start [email protected]
