Panda3D downloads for several distros

Could you try this in the terminal:

sudo dpkg -i panda3d1.8_1.8.1_i386.deb

Of course you have to navigate to the folder where the download is before doing this. If it installs but complains about dependencies, you can fix it with

sudo apt-get -f install

If other errors occure, copy and paste them here, then we’ll look after it
