I am trying to install docker-desktop from here

I downloaded the .deb package

with

sudo dpkg -i docker-desktop-4.8.1-amd64.deb

but I got a couple of missing dependicies problems

I Have tried to install the missing dependicies using

You can fix this by running the following commands:

1. sudo apt-get update
2. sudo apt-get install ca-certificates curl gnupg lsb-release
3. sudo mkdir -p /etc/apt/keyrings
4. curl -fsSL | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
5. echo "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
6. sudo apt update
7. sudo apt-get install docker-ce docker-ce-cli containerd.io docker-compose-plugin
8. Then run sudo apt-get install ./docker-desktop-<version>-<arch>.deb

More info here: Install Docker Engine on Ubuntu

You're not following the instructions, and thus are getting errors.

If you were following the instructions, you would use this command to install: sudo apt-get install ./docker-desktop-<version>-<arch>.deb, and your dependencies would be resolved during installation for you.

dpkg is a low-level tool, that does not automatically resolve dependencies. apt-get (and apt) are higher-level tools that use dpkg, but also resolve dependencies for you.

I had the same problem
I fixed it by iinstalling a docker engine
sudo apt install docker-ce docker-ce-cli containerd.io docker-compose-plugin

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

I tried some of the above solutions but they did not work for me. Hence what I did, I went to the site and first installed the Docker Engine and then installed the Docker Desktop and it worked

Kindly follow these instructions as indicated on the website to download the Docker engine and then go ahead and download the Docker Desktop

That's what worked for me.
