Bug Description

Binary package hint: command-not-found

$ dpkg -l unity
...
ii unity 3.1.4-0ubuntu4 Unity Interface for Ubuntu Netbook Edition

$ unity
The program 'unity' is currently not installed. You can install it by typing:
sudo apt-get install unity

Ideally command-not-found should not prompt the user to install a package that is already installed, regardless of whether the database is out-of-date.

This also happens with misspellings:

$ gnulot
No command 'gnulot' found, did you mean:
 Command 'gnuplot' from package 'gnuplot-nox' (universe)
 Command 'gnuplot' from package 'gnuplot-x11' (universe)
gnulot: command not found

Well ok, I guess it is not that bad in this case, since it does not suggest installing it. It could note somewhere on the suggestion line that it is actually installed, though, while picking up that habit of checking this status anyway.

This now happens with misspellings:

  $ locales

  Command 'locales' not found, did you mean:

    command 'locale' from deb libc-bin (2.31-0ubuntu9)

  Try: sudo apt install <deb name>

  $ dpkg -l libc-bin

This is particularly unfortunate because it could lead to some users unintentionally marking packages as manually installed.
