Description

When following the standard installation instructions for Docker Desktop on Ubuntu 24.04, running
sudo apt install ./docker-desktop-amd64.deb fails.

The system returns an error:
Reading package lists... Done
E: Unsupported file ./docker-desktop-amd64.deb given on commandline
The file is unsupported, even though the .deb package is valid.

The installation succeeds if the absolute path is provided instead:
sudo apt install /home/user/path/to/docker-desktop-amd64.deb

Location

https://docs.docker.com/desktop/setup/install/linux/ubuntu/

Suggestion

apt should resolve the local path and install the package along with its dependencies. Since it doesn't at the moment, add the work around sudo apt install /home/user/path/to/docker-desktop-amd64.deb stated in the description to the documentation.

Hi @ket3l4 The command in the docs (sudo apt install ./docker-desktop-amd64.deb) assumes you’re running it from the directory where the .deb file was downloaded. The ./ prefix refers to the current directory, so running it elsewhere will cause apt to fail. So the documentation is correct as written, though we could consider a small clarification.
