I'd recently installed a package and discovered my scp stopped working. After removing and installing some things I got it fixed but then I stated getting errors in apt-get about

dpkg: error: configuration error: /etc/dpkg/dpkg.cfg.d/multiarch:1: unknown option 'foreign-architecture'

so I commented it out and thought that fixed the problem until I discovered the chrome icon in my launcher turned into a ? and chrome no longer worked. I tried to reinstall it and got the apt-get error:

"ambiguous package name 'libglib2.0-0' with more than one installed instance"

if I try to remove libglib2 I get the error

The following packages have unmet dependencies:

iceape-browser :   Depends: iceape but it is not going to be installed
iceape-chatzilla : Depends: iceape (>= 2.7.11) but it is not going to be installed
                   Depends: iceape (<= 2.7.11-1.1~) but it is not going to be installed
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.

so then I tried to remove icape-browser and it complained about the 2 instances of libglinb2. in fact virtually any command I issue does the same thing so I don't know what I can do to untangle things.
