[Bug 1512992] Re: package zlib1g-dev 1:1.2.8.dfsg-2ubuntu4 failed to install/upgrade: trying to overwrite '/usr/include/i386-linux-gnu/zconf.h', which is also in package lib32z1-dev 1:1.2.8.dfsg-2ubuntu4

[Pat Ferrel]

Just installed Xenial with all updates and can't install zlib1g-dev. It
does not exist in proposed (tried from there) so I assume it's in the
usual update repos. It looks like it is still broken. Is there a work
around?

sudo apt-get -o Dpkg::Options::="--force-overwrite" install zlib1g-dev:amd64
