I experienced this issue on Ubuntu 22.04 jammy.
After installing Docker Desktop following the instructions on the official documentation, and meeting system requirements including having virtualization support, I am unable to launch Docker Desktop. I tried launching it from the applications menu but nothing. As an alternative to launching Docker Desktop from the official documentation, I opened the terminal to run:
systemctl --user start docker-desktop
but I got this error:
Failed to start docker-desktop.service: Unit docker-desktop.service is masked
