The official instructions for removing the CrashPlan Linux app are this:
Linux: Run the uninstaller shell script that comes in the installer package.
Unfortunately the uninstaller doesn’t do a very good job, and leaves a lot laying around. So here’s instructions on how to get rid of everything:
Stop the CrashPlan daemon task
sudo /etc/init.d/crashplan stop
Delete the files
sudo rm -rf /usr/local/crashplan sudo rm -rf /var/lib/crashplan sudo rm -rf /usr/local/var/crashplan sudo rm -rf /etc/init.d/crashplan /etc/rc2.d/S99crashplan
(yes, these could be combined into a simple statement, but I broke them up for ease of reading.)
That should take care of it.
Note that these instructions are based on a Ubuntu installation. And as always, exercise a little common sense with any command that begins in
sudo rm -rf If you break it, you get to keep all the pieces.
