Hence this post explains the following commands on Debian / Ubuntu operating system: List all available packages Search for a package List the available version of a package Install a specific version of a package Install a specific major version of a package Install a specific major.minor version of a package Install a specific major.minor.security version of a package List all available packages apt-cache pkgnames Search for a package apt-cache search jdk List the available version of a package apt-cache madison maven Install a specific version of a package ...
