Ubuntu - Failed to install file: not supported
I'm trying to get an elderly friend to install the .deb teamview file. She is following the steps at
https://community.teamviewer.com/t5/Knowledge-Base/How-to-install-TeamViewer-on-Ubuntu/ta-p/45 and says it will prompt to Authenticate but this doesn't happen.
Instead the Software Installer reports the error "Failed to install file: not supported".
Searching around yields lots of command line workarounds which are just not viable for my elderly friend to perform.
What happened to Quicksupport which was easy to run from a browser?
