Major Issues Upgrading to 0.9.5

Hey all,

It's been manifested to me that I am in dire need of upgrading MuseScore, but I can't for the life of me figure out how to get the newest stable version. I am running Ubuntu Jaunty 64 bit.

When I go to Applications > Add/Remove and try to install mscore, it says it's already installed. So I've typed [CODE]sudo apt-get remove[/CODE] and retried from Add/Remove, but I get the same version. I've done the same thing with "purge".

I've tried installing the .deb file of the package from SourceForge, and it appeared to install successfully (I did this while 0.9.4 was still installed). I then clicked on MuseScore under Applications, but 0.9.4 still started up (except this time with errors that say [CODE]Error loading plugin
usr/share/mscore-0.9/plugins/tuning.js line 30:
ReferenceError: QColor is not defined[/CODE]((I also got one for "colorstones.js"))

Then I "sudo apt-get remove"'d mscore again, and reinstalled the 0.9.5 .deb package. MuseScore was not listed under Apps > Sound/Video, and was not recognized by typing "mscore" in the Terminal.

I went to the MuseScore website and a link said "There are ready-to-install packages for Ubuntu 8.04+ in the "universe" repository, and for 7.10 in the "universe" Backports repository. The packages provided are often older versions than the current stable version.Please consult your favorite package manager for the "mscore" package, or click here to install directly from your browser." I don't know what the former half of that means, but clicking there to install directly from my browser sounded easy enough, so I clicked it, but I got an alert saying that "mscore was already installed on this system" when MuseScore was installed (I thought it would have upgraded).

I just tried it again with MuseScore NOT installed, and it looked like it went through the correct motions of installing it, but when I opened it, lo and behold, 0.9.4 haunts me yet again with the same errors as above.

I am at a complete and utter loss of how to upgrade to 0.9.5. Please assist. T____T;
