How to install specific version of Chromium on Ubuntu?

Question

I've Ubuntu 18.04 and it has Chromium 80 installed on it. I want to downgrade it to Chromium 79.0.3975.79 hence trying to install it.

With command sudo apt-get install chromium-browser, it installs latest version. To install specific version, I tried -

sudo apt-get install chromium-browser=79.0.3975.79

but it gives - Version 79.0.3975.79 for chromium-browser not found.

Could you please help me how to downgrade chromium?

Note: I am trying to install chromium not chrome

Solution

The version you're trying to install for 18.04 is wrong. Correct version is 79.0.3945.79 there's also newer 79 version available.

You can add Chromium Team official repository:

git clone https://git.launchpad.net/~chromium-team/chromium-browser/+git/snap-from-source

Here's the list of available packages in 18.04 click here

There's no such version for 18.04 as you're trying to install, check here launchpad.net/ubuntu/bionic/+source/chromium-browser

[JoKeR]

it's 79.0.3945.79 not 79.0.3975.79

Yes by mistake I placed 3975, my intention was 3945
