Comment 11 for bug 1769693

I agree that the correct fix should be to remove the "patch level" check from the startup code.

I tried opening a ticket on the developer sourceforge page, hoping the maintainer will notice:
https://sourceforge.net/p/protracker/support-requests/3/

Since I don't want to pollute my workstation with a lot of -dev packages just to recompile protracker, as a workaround I keep at hand the older SDL version and I install it with:

sudo dpkg -i libsdl2-2.0-0_2.0.7+dfsg1-2ubuntu1_amd64.deb

(not the ideal solution, though as every system upgrade if not careful will reinstall the latest one)
