JuliaPro, Authentication timeout, Token not found


I have just installed JuliaPro in a computer which ONLY has command line.
I want to use the Knet package. But whenever I use the following command Pkg.add("Knet"), I get an error.

I have authenticated and downloaded the token.toml and put it inside the folder juliapro

Also, the error says that I have to install xclip or xsel. But I am not going to use the GUI.
So, what is it happening?

Did you try restarting your Julia session after downloading the token manually?
