Libstdc++6:i386 dependency issue?

[native-api]

Build suddenly starting to error out - unmet package dependencies

ppa:ubuntu-toolchain-r/test is broken. Some of its packages – libgcc-9-dev in particular – require dependencies (libgcc1 in particular) of greater versions than available in either stock Bionic repos or that PPA. The PPA should be providing those, I guess, since they are a part of the toolchain.
