One (working ?) alternative we've successfully used here to workaround this weird game of whack-a-mole is to stop relying on gcc-multilib, and start using :i386 versions of packages. So for instance, we would install for example the following list of packages on an amd64 machine:
build-essential g++-aarch64-linux-gnu g++-arm-linux-gnueabihf libc6-dev:i386 libstdc++-7-dev:i386 granted the following has been run beforehand: dpkg --add-architecture i386 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1300211 Title: Can't install both gcc-multilib and gcc-arm-linux-gnueabihf To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gcc-defaults/+bug/1300211/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
