What must I do with this installation problem?

I use Gentoo, so I don’t know a lot about Ubuntu. I think you’d have better luck with the Ubuntu forums. Although someone might come along later on and be able to answer this.

Although, I guess the first thing I would do is check the list of installed software and see if whatever you installed last shows up and then uninstall it.

@mrentropy hmmm I’ll see if that works… thanks mate

Did you run the install as a superuser? (sudo apt-get install package_name) Maybe that’s a dumb question, but it never hurts to ask.

Here is a thread in a Ubunti forum about this issue.

In short, try this;
sudo rm /var/lib/dpkg/updates/*
sudo dpkg—configure -a

And try to install again after than does it’s thing.

Run System->Administration->Synaptic Package Manager, in the bottom left-hand corner click Custom Filters, then in the left pane you can see a filter named Broken. Click that to view which packages are broken, right click those packages and select Mark for Reinstallation. Then click Apply on top.
