This has been apparent since my upgrade to 12.04. Just wondering if theres a way to manually open the software center or locate it?
Some ways to start the Software Center from the desktop
1. From the Launcher
2. From the Dash
3. How to bring it back to the launcher
If Software Center is not on your launcher as shown in section 1 above, just start it, and then right-click on its icon in the launcher and click on "Lock to Launcher":
Issue this from commandline and software center should show up (or throw an error)
After it opens pin it to the launcher for easy access.
