On the new released Ubuntu 16.04 desktop, you may get a few error popups that asks you to report problems. Some popups has already been reported so you may want to disable these error popups before they are fixed by upstream.
To do so, you can either temporarily stop the Apport service on current boot, or manually edit the config file to disable error reporting system permanently
1. To stop the Apport service, open terminal (Ctrl+Alt+T) and run command:
sudo service apport stop
Type in password when it asks and hit Enter. There’s no visual feedback while typing your password.
2. To disable the apport system so you’ll never see the error popups, run command to edit config file:
sudo gedit /etc/default/apport
When the file opens, change the value to 0 and save it.
That’s it. Enjoy!
