I tried installing Chromium from the Software GUI. Nothing happened and top showed no chromium process running. I tried launching chromium-browser from the CL and got a Gtk Message error: Failed to load module "canberra-gtk-module"

I found this answer and ran

sudo apt install libcanberra-gtk-module libcanberra-gtk3-module

This did not solve the problem, and now the error message was (and remains):

Gtk-Message: Failed to load module "canberra-gtk-module"
Gtk-Message: Failed to load module "canberra-gtk-module"
Trace/breakpoint trap (core dumped)

and

[ERROR:sandbox_linux.cc(384)] InitializeSandbox() called with multiple threads in process gpu-process.

The latter error sometimes occurs before Trace/breakpoint trap (core dumped) and sometimes after. It doesn't give me back my command prompt but puts me on an unadorned new line (no > or other sign of being inside a program). I have no idea what's going on, so I type ^C to escape.

So I uninstalled Chromium with the Software GUI (which uses snap). I tried installing with apt, got the same error, and uninstalled. Because I learned that apt just calls for a snap install, I used snap install chromium and have installed, removed it, restarted and reinstalled.

I revisited the answer linked above and ran

sudo apt-get install libcanberra-gtk-module:i386

which installed nine 32-bit packages. It did not solve the problem.

I'm out of ideas. I am still pretty new to Ubuntu.

  • Uninstall everything that you installed. Undo everything that you did. Then, when it's all cleaned up, try: sudo snap install chromium. The Chromium packagers only release snaps. – user535733 Sep 15 '20 at 17:20
  • To be fair to Rob, he does state he tried using the snap. – Kurankat Sep 16 '20 at 03:13
  • With respect, "when it's all cleaned up" is not a helpful guideline, esp. to a new user. – Rob Collins Sep 16 '20 at 11:57
  • @RobCollins I have the same issue. Nothing on the thread you linked worked for me, either. Have you had any luck? I've tried installing with both apt and snap, neither work. – Daniel Sep 18 '20 at 08:35
