I got tennis shoes older than you, (literally a pair of original Converse I bought new back in the 1970s). I was there before the original chains of Unix, DOS, and finally Linux were foraged. I saw OS2 die in battle. And I saw the dark time of when paper and pencils and slide rules vanished from this earth.

The knowledge of apt-get and apt only matters to those warriors of the Cli when they wield the sword of sudo to vanquish the evils that exist when upgrading. For they do the bidding of the dark wizards of Dev, holders of the command su.

Now that I have demonstrated my age by showing everyone how senile I am. ‘apt install’ is aimed at users to give a nicer response to it’s use. It need not be backwards compatible either. ‘Apt-get install’ is older and is meant to be usable as a lower level command and to work with other APT based tools.

What does this mean for you today? Not a damn thing. I still always type: sudo apt-get install when using a deb based dsitro out of sheer habit. But it’s not needed the vast majority of the unwashed masses. So feel free to just type apt install to help prevent carpel finger nail.
