I'm using an old version of OpenSUSE and when I try to update some package via the command line, e.g. Zypper update firefoxit shows the message listed below.System management is locked by the application with pid 2181(/usr/sbin/packagekitd).  Close this application before trying again.
Command line error in OpenSUSE (old version)
linux;opensuse;zypper
You already have a Zypper instance running, that's what the error message is telling you. Just kill the other process and try again:sudo kill 2181If that doesn't work trysudo kill -9 2181
