software management is not working

hello everyone
this is my first post
the problem i faced is
when i open package managment in yast
it is showing error message
“accessing package management failed”
system management is locked by the application with pid 3934(/usr/sbin/packagekitd) close the application before trying again


Close the updater applet in your system tray, wait a few seconds, then try again. This happens when the updater applet is trying to check for updates at the same time you’re opening software management.

Take Care,
