error: Unable to lock /home/gerry/.hplip/hp-toolbox.lock. Is
hp-toolbox already running?
[gerry at f10beta ~]$ ps aux | grep hp-toolbox
gerry     4020  0.0  0.0   4212   704 pts/0    S+   22:44   0:00 grep hp-toolbox

It is evident that no other instance is running.

Are others seeing this?  It works fine in F9.
