Hi Rdcinhou... we are like crazy trying to find what happened with this installation.
It's actually a mistery, because with brand new devices, first thing installing canola never failed here in no device, with any firmware.

But if any kind of application is installed, we don't know for sure what or what repository still, sometimes... not always it messes up with application installer.

But can also be thing of server corrupting packages in the download.. I don't know... because I saw that some mediabox user had the same problem there ;/ the thing is.. the application installer seems to really break (segmentation fault) and then is really broken, a apt-get command is needed to get it back to work.

I will expect your feedback as we try to nail this problem to provide a real safe instalation / removal process in future versions.
