Whenever I try to use apt-get to install something I always get this error.

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
libimobiledevice-utils : Depends: libimobiledevice1 (>= 1.0.2) but 1.0.1-1ubuntu0.1 is to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

I already did 'apt-get -f install' but it doesn't fix anything. Here is the output.

Have you recently tried downloading and installing an independent package with dpkg -i? I recently tried to install a google earth deb that was going for different repositories than my Debian OS was on. I think it was looking for Lenny and I was on Squeeze. If you did try to download and install an independent deb package then you need to deselect it for installation.

Is deselecting a package the same thing as removing it? How do I do that?

Deselecting and removing are different. Deselecting is when a package is not installed yet where as, removing is when a package is installed and it is uninstalled. Go into the aptitude application itself and I am pretty sure that you can some how view your selected packages to be installed. It has been a minute since I have played with the GUI aptitude app. If all else fails you can check out the man pages with the command of: I KNOW that there is a command option to view selected packages.

Hi,

looks like shoddy packaging. It seems that although both libimobiledevice0 and libimobiledevice1 provide the same file, the pacakges do not conflict. Are both of these from actual Ubuntu repositories or are they from some third party?

Anyway, you should be able to sort this out by removing libimobiledevice0.

Eg.
