Bug 318415

I realize that this only happens if you forget that you are installing packages, and one should know better. However, sometimes one forgets what is running.

I was installing updates using Muon. I went to do things in other windows. I decided to log out. The system logged out. I logged back in and got a update notification. Unfortunately, I had unfinished updates. There was a lock file preventing updates and there was a partial folder.

Reproducible: Always

Steps to Reproduce:
1. Install packages in Muon.
2. Log out.
3. Log back in.
4. Install updates.
Actual Results:  
The system logged out. I logged back in and got a update notification. Unfortunately, I had unfinished updates. There was a lock file preventing updates and there was a partial folder.

Expected Results:  
When one tries to log out while an installation is running, there should be a warning from Muon that installation has not finished. One should be given an option to cancel the installation and log out or stay logged in and finish the installation.

I'm running Kubuntu 13.04 Raring Ringtail. I realize that this is something that may rarely happen and that Linux is not supposed to be idiot proof or try to be Microsoft Windows. I just feel like this is something that would be helpful and save headaches for users and those trying to help them when they don't know how to fix this situation created by a user's mistake. (I did though.)

With more people moving to Linux and the popularity of KDE and Ubuntu, there will be more users likely to make this same mistake which could be avoided with a warning feature.

I suppose there could be something set even deeper within APT, but since that is a back end, I don't know if that is preferable. I believe it would be preferable, workable, and desirable to add this to Muon as the front end instead.
