Broken dependency, unable to update or install packages

[Luther]

When using apt-get install:

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 python3 : Depends: python3-minimal (= 3.2.3-5ubuntu1) but 3.2.3-5ubuntu1.1 is to be installed
 python3-dev : Depends: python3 (= 3.2.3-5ubuntu1.1) but 3.2.3-5ubuntu1 is to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

It looks like the '=' should be '>='. If I run 'apt-get -f install', it tries to uninstall a very large number of packages.

The dependencies are correct. Why is python3 being installed at a
lesser version than the others?

As suggested in parenthesis, you can possibly bypass whatever is the
problem by running the original command and appending
“python3=3.2.3-5ubuntu1.1”.

 status incomplete

NOTE: Today, 'apt-get -f install' gave me different results. It upgraded
'python3 python3-dev python3-minimal' instead of trying to uninstall
apparently everything that depends on python3. My current problem seems
to be fixed, but I don't know the bug that caused it.

NOTE2: Today is the first time I ran 'sudo apt-get update' from the
command line, though I assume that must have been happening
automatically. (I was unable to update for several days.)

I got the same error message from the following commands:
sudo apt-get install libncurses5-dev
sudo apt-get upgrade
sudo apt-get upgrade python3=3.2.3-5ubuntu1.1

I also got a similar error from the Update Manager, which was trying to
update python3 and python3-minimal, among others.

I didn't ask for it. I can only assume there must have been a mismatched
version number in the package list.

Anyway, thanks for the guidance.
