muon-installer removed after failed update, won't reinstall (libqtgui4 wrong version)

[electrictweed]

I just had a security update fail and both the muon software center and muon package manager have uninstalled. If I try to reinstall...

brandon@brandondesktop:~$ sudo apt-get install muon-installer
[sudo] password for brandon:

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help resolve the situation:

The following packages have unmet dependencies:
 muon-installer : Depends: libqtgui4 (>= 4:4.8.0) but 4:4.7.4-0ubuntu8.1 is to be installed
E: Unable to correct problems, you have held broken packages.
brandon@brandondesktop:~$

Anyone else having this issue? If I try and install the 4.8.0 or later release of libqtgui4 with a .deb file I get this message:

Error: Breaks the existing package "libqt4-declarative"

Anyone know a fix for this issue? It'd be really nice to get muon back...

Thanks!

I am having the same issue. Did you get resolved? Or did anyone else find a fix?

I wonder whether you've added a PPA that might result in a dependency mismatch. Please show the output of

ll /etc/apt/sources.list.d/
