Should be able to cancel installation by rejecting EULA

[Amanda Bee]

It isn't clear how to reject the EULA and cancel the installation of ttf-mscorefonts-installer.

Installing via Synaptic, I first get a dialog that includes the full text of the EULA and a checkbox labelled "Do you accept the license terms?" There is a help button and a forward button but no way to explicitly decline the EULA.

On the second step, a user who has selected "Forward" without checking the EULA box sees a new message:

> Declined "TrueType Core Fonts for the Web EULA "
> If you do not agree to the "TrueType Core Fonts for the Web EULA " license terms you cannot install this software. the installation of this program will be cancelled:

However, installation is not cancelled. `dpkg-query` clearly shows the package as installed:

    amanda@mona:~$ dpkg-query -l ttf-mscorefonts-installer
    Desired=Unknown/Install/Remove/Purge/Hold
    | Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend
    |/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad)
    ||/ Name Version Architecture Description
    +++-==============-============-============-=================================
    ii ttf-mscorefont 3.4+nmu1ubun all Installer for Microsoft TrueTyp

The first screen should give a user the option to explicitly reject the EULA, and having rejected it, installation should actually be cancelled.

Sorry, should have added, I'm on Ubuntu 13.10

There is a good discussion of this at:

http://askubuntu.com/questions/425085/did-i-accept-the-tts-mscorefonts-installer-eula/425105

 + because the package `ttf-mscorefonts-installer` is included in other meta packages (or can be), the error should make it clear what package will be affected by this EULA
 + It isn't clear what "This software" refers to in the error message. It appears, based on behavior that "this software" means the fonts in the TrueType Core Fonts for the Web package. Not the `ttf-mscorefonts-installer` package.
 + "The installation of this program will be cancelled" is similarly cryptic.
 + I didn't have the opportunity to actively decline, I simply did not accept. Saying I "declined" suggests that I managed to so something.

A more clear message might be this:

> You did not accept "TrueType Core Fonts for the Web EULA "
> If you do not agree to the "TrueType Core Fonts for the Web EULA " license terms, ttf-mscorefonts-installer cannot install these fonts. This installer package has been installed, but installation of the "TrueType Core Fonts for the Web" will be cancelled.

Note that there's also a typo in the form of an extra space in `for the Web EULA "`

When you reject the license, the fonts are not installed. The installer is free software, the EULA applies to the fonts that are downloaded from an external site, not to the installer package.

I agree that the text could be improved to make this clearer to everyone.

Status changed to 'Confirmed' because the bug affects multiple users.
