Thanks for the tip on 188.8.131.52.
I tried Ubuntu Studio 18.10 and was able to install BBM but BBM would not run regardless of which version of Windows I specified. This may have more to do with the Studio tweaks than 18.10 (though I have not tried installing a stock version of Ubuntu 18.10).
I pulled down Xubuntu 18.04.1(as I like the XFCE desktop) and iinstallled WINE from the softare repo. BBM installed with no problem. BBM ran with no problem. I did not tweak anything in WINE.
Now I just need to install Hydrogen, Jack control, and a low latency kernel.
