Package: libevent-dev Version: 2.0.21-stable-3 Severity: normal Dear Maintainer,
While bug #675320 added support for multi-arch for the main packages, it seems the development package was overlooked. As such, it is not currently possible to install the dev package for multiple architectures (eg. amd64 and i386) at the same time. Trying to co-install multiple variants results in apt-get/aptitude trying to first remove previously installed packages. Here's the trace when trying to install the i386 variant on a system where the amd64 variant is already installed: $ sudo aptitude install libevent-dev:i386 The following NEW packages will be installed: libevent-core-2.0-5:i386{a} libevent-dev:i386{b} libevent-extra-2.0-5:i386{a} libevent-openssl-2.0-5:i386{a} libevent-pthreads-2.0-5:i386{a} 0 packages upgraded, 5 newly installed, 0 to remove and 2 not upgraded. Need to get 569 kB of archives. After unpacking 1,971 kB will be used. The following packages have unmet dependencies: libevent-dev : Conflicts: libevent-dev:i386 but 2.0.21-stable-3 is to be installed libevent-dev:i386 : Conflicts: libevent-dev but 2.0.21-stable-3 is installed The following actions will resolve these dependencies: Remove the following packages: 1) libevent-dev [2.0.21-stable-3 (now, stable)] Accept this solution? [Y/n/q/?] q I checked the control file in testing/sid (libevent-2.1-6 (2.1.8-stable-4)) and the problem is also visible there.
