Installation of OSCAR in Ubuntu 16.04 ?

[anderson5420]

I don't have a Windows computer. I use a Chromebook running Ubuntu 16.04 under crouton (NOT Crostini). On the OSCAR download page, there is no .deb file for Ubuntu 16.04, only 18.04 and 20.04. I downloaded the 18.04 .deb file and tried to install in in 16.04, no she go. "Unmet dependencies" are of course the bane of all Linux. Here is the result of my attempt to install OSCAR, am I just SOL or cam somebody offer some advice? Request to OSCAR team - distribute this as an AppImage please, so no arcane installation problems!

oscar_1.2.0-Ubuntu18_amd64.deb
(xenial)pat@localhost:~/OSCAR$ sudo apt install ./oscar_1.2.0-Ubuntu18_amd64.deb[sudo] password for pat:

The following information may help to resolve the situation:

The following packages have unmet dependencies:
 oscar : Depends: libdouble-conversion1 but it is not installable
         Depends: libqt5core5a (>= 5.9) but 5.5.1+dfsg-16ubuntu7.7 is to be installed
E: Unable to correct problems, you have held broken package

Thanks for any assistance.
