Actually, they do the same thing simply update the package and repository information. You may notice that the “ sudo apt-get update” and “ sudo apt update” commands are very similar and used interchangeably. OperationĬompare “sudo apt-get update” vs “sudo apt update” Commands Let’s compare these commands with each other for different aspects. Generally, the “sudo apt-get update” command is compared with the “ sudo apt-get upgrade” and “ sudo apt-get dist-upgrade” commands. Compare “sudo apt-get update” vs “sudo apt-get upgrade” vs “sudo apt-get dist-upgrade” Simply the sudo command give the ability to run “apt-get update” command to run as a regular user by elevating privileges. So this means the “apt-get update” command can be only run as a root user or a user with sudoer which can be provided with the sudo command. The package management and apt-get requires root privileges. the “ sudo apt-get update” command simply get this package information from the repository. Apart from the apparent differences between commands, apt also introduced changes to the output design. Also, it was simpler to use as you didn’t have to switch between apt-get and apt-cache. Before updating or upgrading packages the package information should be fetched from the repository. Note: The apt command is more user-friendly compared to the existing APT tools. Can you use sudo apt-get dist-upgrade as your regular upgrade tool Certainly. A repository is a online or internet based package repo which contains package files and meta data. Apt-get upgrade does not remove packages, it only upgrades. In order to install or update a package the package information is provided via repositories. The apt-get command is used to manage packages by installing, updating and removing them. But what does the “sudo apt-get update” comman do? What Does “sudo apt-get update” Do? If you are using a newer version the “sudo apt update” command is used. 21 given that Seth s comment is almost 2 years old, I thought I would add now that it is available, installed and usable out of the box. One of the most used package management commands is “sudo apt-get update”. use the deb packages and apt-get for package management. To update the local package index with the latest changes made in the repositories, type the following: sudo apt update Upgrade packages. If you're forcing a specific patch level ( python:3.8.4) you're at some risk, since these images stop getting updates once a newer upstream version is released.Linux distributions like Ubuntu, Debian, Mint, Kali, etc. Update the package index The APT package index is essentially a database of available packages from the repositories defined in the /etc/apt/sources.list file and in the /etc/apt/ directory. Hence, it recommended option is always to run update command before upgrade command to update installed packages for an Ubuntu or Debian system: sudo apt-get update & sudo apt-get upgrade. If you're using a major-version or minor-version image tag ( python:3, python:3.8, python:3.8-buster) you're probably okay, so long as you make sure to update your base image to something listed on the Docker Hub image page periodically. While sudo apt-get upgrade does an actual software upgrade. It is unusual, but not unheard-of, to run apt-get update and similar "upgrade everything" commands in a Dockerfile it is more common to either assume the base image is up-to-date already, or to have specific provenance requirements and build everything from scratch on top of a base distribution image. You're somewhat dependent on intermediate images, like python:3.8, doing the same thing. The base Docker Hub Linux distribution images like ubuntu:18.04 actually update themselves fairly regularly: if you docker pull ubuntu:18.04, wait a week, and repeat it, you will get a newer image.
