The PPC emulator, Rosetta, also required a full compliment of PowerPC libraries and frameworks installed. Though 10.6 did not support booting on PPC and only included Intel drivers, the basic system frameworks were still Universal Binaries — PPC code was included.
A Rosetta-like approach won't work on Ubuntu 19.10 as there will be no 32-bit packages, hence no libraries/frameworks in the appropriate architecture for the Rosetta-like layer to call into.
