I had taken online 2 hours class, but the trainer not able to let us know how to install it and told to resolve error next day and I found this video where in 2 mins I installed docker successfully...🤣🤣🤣
very good except if you stop here specifically on Ubuntu your container don't have internet access because the resolve file is empty on Ubuntu, another way to say it's useless. But technically yes you have "installed docker" and it's "up and runing"... but useless.
If you have a problem with some dependencies, like: The following packages have unmet dependencies: docker-desktop : Depends: curl Depends: qemu-system-x86 (>= 5.2.0) but it is not going to be installed Depends: docker-ce-cli but it is not installable Depends: pass but it is not going to be installed Depends: uidmap the only thing you need to do is run this command before Docker installation: sudo apt --fix-broken install
