I am new to Linux and just installed Ubuntu 22.04 LTS version. I follow the instructions on Docker website to install Docker Desktop on my Ubuntu but failed. Below is what I have done:

1. Set up Docker’s package repository.

   
   

   $ sudo apt-get update
   
   
   
   $ sudo apt-get install 
   
       ca-certificates 
   
       curl 
   
       gnupg 
   
       lsb-release
   
   
   
   $ sudo mkdir -p /etc/apt/keyrings
   
   
   
   $ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
   
   
   
   $ echo 
   
     "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu 
   
     $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
   
   

   
   



2. Download latest DEB package from the release page.
   In my case, I downloaded docker-desktop-4.10.1-amd64.deb

   
   



3. Install the package with apt as follows:

   
   

    $ sudo apt-get update
   
   
   
    $ sudo apt-get install ./docker-desktop-<version>-<arch>.deb
   
   

   
   

However when I ran the last command, the terminal gave an error: E: Unsupported file ./docker-desktop-4.10.1-amd64.deb given on command line

How to fix this problem?
