Simply Download this PB2Launcher-1.deb package and install it (do not select "Open with Software Install", chose "Select File" when prompted instead. In else case Software Install application will show "Failed to install file: not supported" message).
Note: Ubuntu seem to have issue where it won't be able to install .deb package without Internet access. For this case you can download .deb file and try option 2.
This method would work if installation needs to be done on systems without Internet access.
Download .deb file from option 1 and save it somewhere, for example at /home/eric/Desktop/PB2Launcher-1.deb (this path will be used in command below)
Copy and paste following command into your Terminal application:
sudo dpkg -i "/home/eric/Desktop/PB2Launcher-1.deb"This command will also require you to enter your operating system user password (not related to this website).
sudo apt-get purge --auto-remove pb2launcher
