installer not in UTF-8

I’m on UbuntuStudio 16.04, which uses Mouse Pad. It won’t open the run program (for Ardour 5.0) because the ‘document is not in valdi UTF-8’. Any solution?

You should paste the entire output from attempting to run the installer. That error message is unlikely to be the source of your problem. I suspect you are not even running the installer, but loading it into some application that believes that it is a document of some kind.

I updated Ubuntu to 16.04 yesterday. The Mouse Pad program attempts to open the installer as a document. However, I installed Ardour 5 from terminal, so no problem. Tx.
