Background: Running kubuntu 14.04, using kdm. I have a Brother MFC7280N, and installed the brscan2 package. Nevertheless I have never been able to scan, since the device is never found. I removed (I thought) brscan2 in hopes of reinstalling.
I had installed Kompozer, and had to remove it when it started to display funky video. I have tried to reinstall it but without success. I haven't edited any config files, except to add a repository for Kompozer (failed), or done anything other than run apt-get and the software center. That is, I haven't tried any strange (to me) commands to install, remove, or modify the installed software. I did try to install Kompozer from a .deb file and also from two tarballs.
Now I can't install or remove any software using apt-get or the Ubuntu Software Center. Here's an example:
root@LEX:/home/bill# apt-get remove brscan2

Done You might want to run 'apt-get -f install' to correct these: The following packages have unmet dependencies: kompozer:i386 : Depends: libatk1.0-0:i386 (>= 1.9.0) but it is not going to be installed Depends: libcairo2:i386 (>= 1.0.2-2) but it is not going to be installed Depends: libgtk2.0-0:i386 (>= 2.8.0) but it is not going to be installed Depends: libidl0:i386 but it is not going to be installed Depends: libpango1.0-0:i386 (>= 1.12.3) but it is not going to be installed Depends: libxft2:i386 (> 2.1.1) but it is not going to be installed E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
This is so strange that I don't have any notion of what to make of it. So I need some expert guidance. Many thanks!
