I deleted apt-get by accident, and now I'm having problem reinstalling it.

Here is what I did

dpkg -r apt (uninstalled apt-get)

I tried to download apt.deb files and install back with

sudo dpkg -i apt_1.2.32ubuntu0.1_amd64.deb

It gives me this error:

Selecting previously unselected package aptitude:amd64.

Then I tried this :

sudo dpkg -i --force-all apt_1.2.32ubuntu0.1_amd64.deb

It gives me this output:

Now when I'm trying to use

sudo apt-get update 

It gives me this:

You are attempting to install the Ubuntu 16.04 version of apt and not the Ubuntu 18.04 version of apt.

Look at this page for apt (1.2.32ubuntu0.1). Note that the breadcrumbs for the URL in the page is:

» Ubuntu » Packages » xenial (16.04LTS) » admin » apt

That’s clearly the Ubuntu 16.04 version. But you are running Ubuntu 18.04. So you need to get apt (1.6.12ubuntu0.1) which can be found here. Again, look at the breadcrumbs for the URL in the page:

» Ubuntu » Packages » bionic (18.04LTS) » admin » apt

Download it directly from here and just run this command:

sudo dpkg --install apt_1.6.12ubuntu0.1_amd64.deb

And you should be solid.
