completely uninstalling Google Chrome

[ulissipus]

Would anyone teach me how to uninstall completely Google Chrome? I did it via Software manager, then Synaptic to delete "Google-Chrome-Stable". But whenever I use a mail programme I get the following error message:

Failed to execute the default Web browser / Failed to execute child process "/usr/bin/google-chrome-stable" (no such file or directory)

I never chose it to be my "default Web Browser".

Any guidance very much appreciated.

You probably set it without any realization you did.
It'll give the option the first time you start chrome, if you hit the option it sets it as default.
What browser is your actual default?
If firefox, then simply go to the hamburger setting icon then to preferences.
It will have an option to set it as default
(It'll have a line saying firefox is not the default browser, and a "make default" button, click on the button and firefox will be set as the new default.)

I thought so too. I use either Firefox or Opera and have made Firefox the default browser.

I also thought I had wiped out Google Chrome. I didn't obviously. I still get that error message on launching Firefox, for instances.

But I cannot find "google-chrome-stable" in "/usr/bin/"...

Try

locate google-chrome-stable

and even

locate chromium-browser

just in case.

You wrote

Could you share the identity of the mail program? Could it be possible that the mail program is internally set to use a particular browser?

Tks. I never touched in Chromium. The commant -- locate google-chrome-stable -- gave back:

Run

sudo apt-get update

and

sudo apt-get upgrade

and

sudo apt-get purge google-chrome-stable

and post the complete output here.

Thank you. I had thought of that too. However, the output was:

Let's see what the system has to say about the state of chrome

dpkg -l | grep chrome | awk '{print $1,$2,$3}'

This will tell us the install state, if any, the names of the installed packages related to chrome, and the versions installed.
