I have downloaded the vagrant 2.2.9 64 bit setup file from Downloads | Vagrant. It is not a .deb file, it does not have any extension so I can not understand how can I install vagrant using this file. It only shows exec in green letters in the file icon.
How can I install vagrant in my ubuntu 18.04.4 using this file? Or is there any other way to install the latest version of Vagrant?
