apt-get:update
The apt-get update command is a Linux command used to update the package lists for repositories and applications on a Ubuntu or Debian system. This command refreshes the sources for all the packages on the system, including newly added repositories and updates to existing repositories. The package lists contain information about the latest available packages and their dependencies, which are used by the system to manage package installations, upgrades, and removals. The apt-get update command is typically run before installing or updating software or packages on a Linux system to ensure that the package lists are up-to-date. This command does not install any new packages or updates, but only updates the package lists from the available repositories.
