`sudo apt-get install wolfram-engine
`got me an installation in which trying to launch Mathematica from the RPi GUI got me an error box with a message, complaining about an invalid file
/usr/share/raspi-ui-overrides/applications/wolfram-mathematica.desktop
As described in this thread, the offending file has pointers to "10.0" nonexistent directories in the lines headed "Exec" and TryExec"
nanoing these lines to "10.3" and a reboot fixed the failure to launch.
Is this the preferred fix, and are there other, maybe worse things lurking?
Is
TryExec=Mathematica
Exec=Mathematica %F
sufficient?
Preferred?
