yum-updatesd will hold the lock while it's running yum.  It will remove
the lock once its copy of yum exits.  There's no need to do anything
drastic...just wait a few minutes.

I don't know what the "packet manager" is.  Perhaps you mean "package
manager".  If so, you should know that yum runs rpm (the package
manager).  Since only one copy of yum or rpm may run at any given time,
you are prevented from running a second copy.  Again, just wait a few
minutes and it'll all be OK.

However, if you wish to disable yum-updatesd, then, as root:

	chkconfig --level 2345 yum-updatesd off
	service yum-updatesd stop

Don't run "system-config-firewall.py", just run
"system-config-firewall" (without the ".py" at the end).  It must be run
as root.

Or, from Gnome:

	System->Administration->Firewall
