Linux desktop client
You have two ways of installing WARP on Linux, depending on the distro you are using:
- Find the latest WARP client in the package repository.
 - Install the 
cloudflare-warppackage that suits your distro:- apt-based OS (like Ubuntu): 
sudo apt install cloudflare-warp. - yum-based OS (like CentOS or RHEL): 
sudo yum install cloudflare-warp. 
 - apt-based OS (like Ubuntu): 
 
 Using WARP
The command line interface is the primary way to use WARP.
 Initial Connection
To connect for the very first time:
- Register the client 
warp-cli registration new. - Connect 
warp-cli connect. - Run 
curl https://www.cloudflare.com/cdn-cgi/trace/and verify thatwarp=on. 
 Switching modes
You can use warp-cli set-mode --help to get a list of the modes to switch between. For example:
- DNS only mode via DoH: 
warp-cli set-mode doh. - WARP with DoH: 
warp-cli set-mode warp+doh. 
 Using 1.1.1.1 for Families
The Linux client supports all 1.1.1.1 for Families modes, in either WARP on DNS-only mode:

 Feedback
You can find logs required to debug WARP issues by running sudo warp-diag. This will place a warp-debugging-info.zip file in the path from which you ran the command.
To report bugs or provide feedback to the team use the command sudo warp-diag feedback. This will submit a support ticket.
