I am installing Passbolt for the first time on a freshly installed Ubuntu 18.04 system using the instructions at https://help.passbolt.com/hosting/install/ce/ubuntu-18-04-bionic-beaver.html.
I cannot complete step 3 of the installation (Server Keys/ Create a new GPG key for your server), whatever I enter results in the message: “The data entered are not correct: The public key cannot be used encrypt; The private key cannot be used to decrypt.”
I reinstalled Ubuntu but am getting the same message.
Any idea why this is?
The nginx error log is empty.
Is there any other information I should post to facilitate troubleshooting?
