I'm not to familiar with Ubuntu, but I need to install the previous version because the current one has some bugs.

I went to here and found the version that I wanted: http://www.ubuntuupdates.org/package/google_chrome/stable/main/base/google-chrome-stable

Naturally, I tried to install it with apt-get:
sudo apt-get install google-chrome-stable=51.0.2704.106-1

However, after running that command, I received this message and I tried Googling the issue and couldn't find a solution:

ubuntu@box533:~$ sudo apt-get install google-chrome-stable=51.0.2704.106-1

E: Version '51.0.2704.106-1' for 'google-chrome-stable' was not found

ubuntu@box533:~$ 

How can I install an older version of Google Chrome via command line?

You cannot unless you could grab a copy of the version 51 of Google Chrome. Because Google never allow downloading of older releases and what you found on ubuntuupdates.org is just a reference. They do not host any binary files.

Your best bet is to search in some non-techy friend who doesn't update browsers for years (old grandma's pc can help here too) and see if they have a 51.

I managed to install older Chrome very easy. I first installed latest Chrome (v64). Then installed older v61 version from here:

https://www.ubuntuupdates.org/package/core/artful/universe/base/chromium-browser

with this command:

sudo dpkg -i --ignore-depends=chromium-codecs-ffmpeg-extra chromium-browser_61.0.3163.100-0ubuntu1.1378_amd64.deb 

also, make sure to block updates like this:

sudo apt-mark hold chromium-browser

You just run it as dkpg -i on your dist and see if some dep fail.. and if it does, your chance is to list it with --ignore-depends= flag and see if it goes through.

I've used this on my Ubuntu 16.04x64 because on newer versions > v64 you can't use .dev for staging for web dev purposes, see details here:

output from cli is:

krex@krex-N752VX:~/Desktop$ sudo dpkg  -i --ignore-depends=chromium-codecs-ffmpeg-extra chromium-browser_61.0.3163.100-0ubuntu1.1378_amd64.deb
