This question already has an answer here:

What is the difference between the command line sudo apt-get update and the command line sudo apt update?

Although I've been using only Ubuntu and Ubuntu-based distros in the last several years, I still consider myself an entry-level user when it comes about command lines and Terminal-related stuff. I mention this aspect because I need a novice-friendly explanation.

A bit of background info: on a regular basis I run the commands sudo apt-get update and sudo apt-get upgrade in my Terminal. And I also know that it is recommended to do so before installing any app, in order to avoid any errors.

But today I have decided to install snapd on my Ubuntu 14.04 system, and I noticed that, on their webpage there are mentioned these two lines:

sudo apt update sudo apt install snapd

And this is why I am puzzled. (By the way, these lines work fine in my case.)

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

  • @pomsky - I mean exactly the difference between "sudo apt-get update" and "sudo apt update". – Cristiana Nicolae Sep 9 '18 at 12:10
  • Link given by DK Bose got you covered. "apt" is a newer frontend to the debian APT tools than apt-get. You will not have apt available in 14.04 – vanadium Sep 9 '18 at 12:11
  • apt is there in 14.04 as well: manpages.ubuntu.com/manpages/trusty/en/man8/apt.8.html but I don't know if it has the features available in later versions of Ubuntu. – DK Bose Sep 9 '18 at 12:17

    run it and see. for the most part it's the same, but with pretty colors & for some functions a cute status graph, but it's still missing some functionality, and until it has all functionality included, you'll still have the old apt-get installed for when you need those features. sudo apt-get dist-upgrade is now sudo apt full-upgrade, but dist-upgrade still works in apt (even if not in man apt; maybe it'll go when apt-get is finally depreciated? (if that ever happens)) – guiverc Sep 9 '18 at 12:36
  • But see askubuntu.com/a/926850/248158 because, by default, apt install doesn't retain debs in /var/cache/apt whereas apt-get install does by default. – DK Bose Sep 9 '18 at 12:53

Apt is the new frontend. More specifically apt offers the same more-or-less functionalities as apt-get, apt-cache etc in a single command. You can read more about the differencies and similarities here: https://itsfoss.com/apt-vs-apt-get-difference/

    Thank you! The information from the link you provided explains things in a more clear way that the information I got from the other links (including the other AU similar question). It is exactly like I asked: novice-friendly. – Cristiana Nicolae Sep 9 '18 at 13:46
