Here's how to install Docker Desktop on Ubuntu.
Download the .deb file
Go to doc.docker.com and download the latest .deb package.
There are some instructions there on what to do:
sudo apt update sudo apt install ./docker-desktop-4.22.1-amd64.deb
Broken packages problem on install
For me, I had a problem when I tried to install this:
Reading package lists... Done Building dependency tree... Done Reading state information... Done Note, selecting 'docker-desktop' instead of './docker-desktop-4.22.0-amd64.deb' Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: docker-desktop : Depends: docker-ce-cli but it is not installable E: Unable to correct problems, you have held broken packages.
Broken packages, eh? I tried many things to try and fix this. None seemed to work.
Then I found a set of stackoverflow instructions. It said:
The issue you are facing is due to the missing Docker repository on your system
And directed me to the Docker Engine docs (which, as of this writing, are a little different than what's in the SO post):
# allow apt over https sudo apt update sudo apt install -y ca-certificates curl gnupg # add docker gpg key sudo install -m 0755 -d /etc/apt/keyrings curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg sudo chmod a+r /etc/apt/keyrings/docker.gpg # setup up the docker repository echo \ "deb [arch="$(dpkg --print-architecture)" signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \ "$(. /etc/os-release && echo "$VERSION_CODENAME")" stable" | \ sudo tee /etc/apt/sources.list.d/docker.list > /dev/null # one more time sudo apt update
Once I resolved that, I could install docker desktop successfully:
sudo apt install ./docker-desktop-4.22.0-amd64.deb
And test it:
docker version Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

Works. No engine. Just desktop. Commands upon commands.
Start Docker Desktop
To get it started, run:
systemctl --user start docker-desktop
The first time you run it, you won't be authenticated. To set up a user, you'll have to initialize
pass, which is what docker stores its credentials in.
Generate a gpg key:
Copy the public key into this command, and run it:
pass init [your_public_gpg_key]
Then in the docker desktop UI, you should be able to authenticate with this new user, as specified by the email in your gpg key.
