So far my experience with the installation and configuration of Calculate 15 has been TERRIBLE to say the least. The available documentation is inadequate because it is lacking in detail or needs to be updated!
I have tried to create a Certificate and when I used the cl-core --sign-client command, with the ID that was given when creating the signature request, I got the following response.
bash: cl-core: command not found
So, I tried sudo cl-core --sign-client but the Root Password was not recognised.
When replying, please make sure that you provide a comprehensive and fully explained answer!
