This isn't actually a multiarch problem. Following the directions from the referenced site results in installation of an i386 'libaio' package which doesn't even match the official {libaio1,libaio-dev} packages in the Ubuntu archive, let alone supporting multiarch.
So this is an ordinary package conflict between an official package and an unsupported unofficial one. I don't think there's any bug here. If this is a library that's important to have cross-installable as a 32-bit lib on a 64-bit system, we can certainly make *converting* it to multiarch a priority; but it's not a bug per se that it isn't yet converted. ** Changed in: libaio (Ubuntu) Status: Confirmed => Invalid -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to libaio in Ubuntu. https://bugs.launchpad.net/bugs/773891 Title: package libaio-dev (not installed) failed to install/upgrade: trying to overwrite '/usr/include/libaio.h', which is also in package libaio:i386 0.3.104-1 -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
