I deleted apt on Ubuntu, now what?

Apparently if you do

apt purge ubuntu*

You’ll end up deleting apt. Which is a bummer, because you can’t install anything else, or fix the problem. But not to worry, the resolution is fairly easy.

You can go download the apt deb from Ubuntu’s website and install it with dpkg.

Go to the following link and find the packages for your Ubuntu version

https://packages.ubuntu.com/

You’ll need to show “All packages” at the bottom of the page.

https://packages.ubuntu.com/xenial/allpackages

Download and install ubuntu-keyring, apt-transport-https, and apt packages. Example below

wget security.ubuntu.com/ubuntu/pool/main/a/apt/apt_1.6.6ubuntu0.1_amd64.deb
wget security.ubuntu.com/ubuntu/pool/main/a/apt/apt-transport-https_1.2.29ubuntu0.1_amd64.deb
wget mirrors.kernel.org/ubuntu/pool/main/u/ubuntu-keyring/ubuntu-keyring_2012.05.19_all.deb

Install Packages

sudo dpkg -i ubuntu-keyring_2012.05.19_all.deb
sudo dpkg -i apt-transport-https_1.2.29ubuntu0.1_amd64.deb
sudo dpkg -i apt_1.6.6ubuntu0.1_amd64.deb

Run apt and make sure it is all working

sudo apt update && sudo apt upgrade
