In sources.list, I've commented-out everything except:

deb http://http.debian.net/debian wheezy-backports main

from:

http://backports.debian.org/Instructions/#index2h2

apt-get update complains about a pubkey, which is fixed by:

gpg --keyserver pgpkeys.mit.edu --recv-key 8B48AD6246925553
gpg -a --export 8B48AD6246925553 | sudo apt-key add -

from:

http://raspberrypi.stackexchange.com...rts-debian-org

But when I try:

apt-get -t wheezy-backports install pcmanfm

I get a million complaints about dependencies that can't be upgraded to the new pcmanfm.

Konqueror, jags, and komba2 are not available. Have I hit a wall? Or is there another workaround?

Thanks,
Jake
