ubuntu 12.04 armory install failed

Question

i'm trying to install armory on ubuntu 12.04 but it is not working:

$ sudo dpkg -i armory_0.88.1-beta_i386.deb
Selecting previously unselected package armory:i386.
(Reading database ... 222699 files and directories currently installed.)
Unpacking armory:i386 (from armory_0.88.1-beta_i386.deb) ...
dpkg: dependency problems prevent configuration of armory:i386:
 armory:i386 depends on python-qt4.
 armory:i386 depends on python-twisted.
 armory:i386 depends on python-psutil.
dpkg: error processing armory:i386 (--install):

Errors were encountered while processing:
 armory:i386

it looked like i needed to install packages python-qt4, python-twisted and python-psutil so i did this:

$ sudo apt-get install python-qt4 python-twisted python-psutil

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 armory:i386 : Depends: python-qt4:i386 but it is not going to be installed
               Depends: python-twisted:i386 but it is not installable
               Depends: python-psutil:i386 but it is not going to be installed
 python-qt4 : Depends: libqtassistantclient4 (>= 4.6.3) but it is not going to be installed
              Depends: sip-api-8.1
 python-twisted : Depends: python-twisted-conch (>= 1:11.0) but it is not going to be installed
                  Depends: python-twisted-mail (>= 11.0) but it is not going to be installed
                  Depends: python-twisted-lore (>= 11.0) but it is not going to be installed
                  Depends: python-twisted-news (>= 11.0) but it is not going to be installed
                  Depends: python-twisted-runner (>= 11.0) but it is not going to be installed
                  Depends: python-twisted-words (>= 11.0) but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

for some reason they did not want to install so i did this: (was this a bad move?)

$ sudo apt-get -f install

and after a massive amount of output in which it looked like many packages were removed??? nothing happened. armory still won't run and now i think i have screwed up some other valid packages since i have a lot of empty links with question marks on my unity bar. even the vim configuration file seems to have been altered!

help!

(i should also mention that i recently upgraded from ubuntu 10.04 to 12.04 and that may not have gone too smoothly for bitcoind)
