Here is the log as I drilled down the dependency tree. Looks like a problem with libstdc++6:i386. Given that gcc was moved to default to cpp-7 should wine32 and all its dependencies be rebuilt with cpp 7?
I only followed part of the tree, so there might be other problems. David *david@continuum*:*~*$ sudo apt install wine32 *david@continuum*:*~*$ sudo apt install libwine:i386 *david@continuum*:*~*$ sudo apt install libxslt1.1:i386 *david@continuum*:*~*$ sudo apt install libxml2:i386 *david@continuum*:*~*$ sudo apt install libicu57:i386 *david@continuum*:*~*$ sudo apt install libstdc++6:i386 *david@continuum*:*~*$
