system locked?

What can I do about this(?):

linux-4aea:/home/randall # zypper dup
System management is locked by the application with pid 2684 (zypper).
Close this application before trying again.
linux-4aea:/home/randall # killall zypper
linux-4aea:/home/randall # zypper dup
System management is locked by the application with pid 2684 (zypper).
Close this application before trying again.
linux-4aea:/home/randall #

Perhaps the updater is running, look at your systray (On KDE in the bottom right corner by default) for a small green icon and Exit it or see what it’s doing.

Become su and run this:

kill 2684
