Did your Google Chrome browser become unresponsive and it refuses to close or reboot?

On Ubuntu, you can force quit the Google Chrome application by using the pkill command in your terminal.

If you don't already have a terminal window open, you can open one with the CTRL+ALT+T keyboard shortcut.

Then, execute this command in your terminal to kill all processes running the Google Chrome browser on your machine:

      sudo pkill -9 chrome

This command runs the pkill command with the -9 option, which is the SIGTERM signals used to tell a process to terminate.

After successfully running that command, all the instances of Google Chrome running on your machine should now be closed and terminated.

If you don't want to kill all the Google Chrome processes running on your machine, you can also kill individual processes. To do this, you need to first list out all the PIDs (Process Identifiers) running Google Chrome and then use the sudo kill -9 PID command to kill that specific process.

You can list all the processes running the Google Chrome browser with this command:

      ps aux | grep chrome

The command uses ps aux to get all the processes running on your machine and then grep chrome to filter out everything but processes running Google Chrome.

This will output something that looks like the following:

      nick     2810  0.0  0.8 778456 140952 ?       Sl   17:55   0:17 /opt/google/chrome/chrome ...

The first number you see in the output after the username (2810 in the example output above) is the PID for that specific process.

You can also modify the output to only show the PID numbers:

      ps aux | grep chrome | awk '{ print $2 }'

This output will look like this:


Now that you have the PID/s for the process running Google Chrome, you can end it with this command:

      sudo kill -9 PID

That will kill only the specific PID number you give to the command.
