Bug Description

Binary package hint: software-center

When installing a new package that conflicts with another already installed package, Software Center will silently uninstall any conflicting packages from the computer.

Steps to reproduce:
1. Start the Software Center
2. Install Miro
3. Exit the Software Center
4. Start the Software Center
5. Install Gourmet Recipe Manager

Miro is removed without any notification or prompt.

Expected results:
Software Center should inform the user that a conflict has been detected and ask if they would like to continue with the installation or cancel.

I'm affected as well.

Miro was a victim of Software Center and the Ubunter video viewed via itself. :-)

PS: For the bug related with the actual conflict see Bug #355866 and for my workaround comment #9

Back to apt-get for now

Aptdaemon provides a Simulate method which allows to calculate the dependencies of a transaction. This one should be used. See the gtk-demo or aptdcon for a code example.
