that is correct. I am trying to at this point, just BYPASS the HTTPS, since this will be behind a firewall anyways and I will hopefully be using the CloudFlare tunnels to access this externally. Right now I can’t even just get the “site” running to be able to access it. I am currently running, but it seems there is some error?
Regarding not having rights for the hosts file, any modification will need to be done by either the root user or by using sudo with a user who is in the sudo group.
sudo nano /etc/hosts
If you are not intending to follow the other guide to its intended end, have you considered following the official passbolt guide instead?
It will install by default to https://passbolt.local with a self-signed cert.
