When I click "Install" in the software center, it fails silently, doing nothing. I then checked the command line, and got this error

It is a known bug. As gatoatigrado mentioned, running the Software Center as root or installing by command line are ways of getting around it.

There seems to be a workaround. A similar bug was manifest in the update manager in 11.04, so I modified that command line. Instructions:

  • Launch the terminal with Ctrl+Alt+T
  • Paste (without quotes) "gksudo software-center & exit"
  • Press enter.
  • Enter your password.

Ironically, the workaround is a little more convenient after started, since you don't need to type your password repeatedly when installing multiple programs.
