java install bug?

[Mike Dugger]

I have just installed studio on an older machine for my nephew. In 
trying to install java using apt-get (so that flash will function) the 
install stalls on the terms/licensing screen within the terminal. See 
screenshot at:

I can find no way to exit this screen to complete the installation. 
Clicking on "<Ok>" doesn't work. Hitting "Enter" doesn't work. The 
scrollbar functions, but the java installation is simply stuck at this 
point. Is there some kind of Sun Systems secret handshake necessary to 
accept the terms and continue the installation or what?

I've tried simply exiting the terminal, but when I open synaptic it 
complains that it is "Unable to obtain an exclusive lock" which would 
seem to indicate that apt is still running. But apt doesn't show up in a 
ps listing so I can't kill it. The trouble seems to be that var/lib/dpkg 
is locked and until I can get it unlocked  I can't install anything else 
with either apt-get or synaptic. Is there a superuser method to unlock 
the directory?

If I reboot, the java installation immediately starts over and hangs up 
at the same place. I'm stumped. If I could end the loop I could try 
installing with synaptic instead.

I'd appreciate any help in solving this problem.
