Whenever I try to open chromium from the desktop, I get a loading cursor, then nothing happens. I tried to start it from terminal to see what the problem was, and it returned this error:

Try to re-install it to avoid any corruption in its files:

sudo apt-get remove chromium-browser
sudo apt-get autoremove
sudo apt-get install chromium-browser

    Before installing chromium-browser again it would be a good advice to sudo apt update && sudo apt full-upgrade and reboot if you have a lot of updates.

You can try rename chrome folder ,inside /home/your_user/.config/ , as backup and try to open browser . Automatically it creates a new one folder. It has been working for me when upgrades or updates break configs .

  • Didn't work. Returned the same stack trace as before. Commented Nov 12, 2016 at 19:15

I was able to get Chromium running on a Zero W using the Buster Legacy OS, 2023-02-21 release (Version 3.6 January 2021).

But... I had to install with default pi user account (different password). It didn't work if I installed the image with a different user account name, admin.

Manually installed Chromium using sudo apt install chromium-browser

I couldn't get Chromium to run in Bullseye on RPi0W.


If you have previously been using Chromium on your raspberry pi but are suddenly unable to get it to run, it's most likely that Chromium did not close properly. Head to /home/user/config/chromium/ and delete the files 'SingletonCookie' 'SingletonLock' and SingletonSocket (red triangle! icons). Chromium will open now and you haven't lost any settings, extensions or other data.
