I am installing ISPConfig 3 on a Ubuntu 20.04 server. In order to do this correct I purchased the Installation Manual for ISP Config. Chapter 3.1.1 HVVM and Let's Encrypt The instructions to install Let's Encrypt advise to: Code: mkdir /opt/certbot cd /opt/certbot wget https://dl.eff.org/certbot-auto This doesn't work as it gives an 404 error that the page is not found. It's a bit disappointing to pay for an installation manual and then already on the first steps you run into to problems that the installation procedures described do not work. According to the certbot site this seems to be done now via snap install. But then the snap install is linked into /usr/bin/certbot and not /opt/certbot/certbot. Question: If I use the available snap install will ISPConfig work with certbot in /usr/bin or do I need to link it into /opt/certbot?
