To follow-up on my previous comment, I was able to work around this "broken state" in aptitude by purging the offending packages with "--force-depends":
dpkg --purge --force-depends "gcc-multilib" dpkg --purge --force-depends "lib32z1-dev" dpkg --purge --force-depends "libc6-dev-x32" Now, I'm able to use "apt-get" as normal. Hopefully, this workaround won't cause problems in the future. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1365375 Title: package libc6-dev-i386 (not installed) failed to install/upgrade: trying to overwrite '/usr/include/gnu', which is also in package libc6 -dev-amd64 2.19-0ubuntu6.3 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/eglibc/+bug/1365375/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
