[SOLVED] Cloudflare warp daemon error when register the client

Hi, I use xubuntu 18.04. I installed warp client for ubuntu 16.04, I have an error when register the warp client:

[email protected]:~/Desktop$ warp-cli register
Unable to connect to CloudflareWARP daemon. Maybe the daemon is not running, or is connected to another process?

How to solve it? Thanks.

sudo systemclt start warp-svc.sevice
