Lock file & Debs over NFS

["Brendon Baumgartner" <brendon@brendon.com>]

I can't get access to my debs on my desktop over the network. This lock file
is getting in my way!

Okay my laptop hostname is debian (just installed) and my desktop is viper.
For some reason when I do apt-get dist-upgrade, a lock file is created and
it won't delete it and complete the command. Also, my archive cache
directory has been changed to /mnt/debs on both machines. It works fine on
my desktop, but the laptop which accesses the debs via nfs doesn't like it.
Any ideas?

debian:/mnt/debs# rm lock
debian:/mnt/debs# apt-get dist-upgrade
