I had the same problem on my N800. Even if Installing canola I had an error message, canola was installed and run. But it couldn't find any of my audio or video files. So after a few tries, I disinstalled canola, and disabled all repositories except: Nokia Catalogue, Nokia Catalogue (3rd party) and the Canola repository: http://openbossa.indt.org.br/canola/...ory-beta2/bora distribution: bora component: user Then I successfully installed Canola without any error, and now it runs, sees my audio and video files, even after re-enabling the other repositories
