As I continue to configure my Zorin Core VM, the next step was to be installing Vivaldi and configuring that. However, I download the .DEB file from the Vivaldi web site, and Zorin's Linux software installer wants nothing to do with it. Says "Failed to install file. Not supported." I tried with a different .DEB file, and the same thing happened.
This is an apparent change since the last time I worked with this OS, because at that time I had no problem installing Vivaldi this way.
Does anyone know what's up with that? Zorin's an Ubuntu offshoot, and uses apt in the terminal to install packages. Why wouldn't it install a .DEB file?
