Have you tried running aptitude and switching to amd64 packages with it (and using its dependency resolver interface)? I find that aptitude's interactive dependency resolver makes packages management easy. Just an idea; I have never needed to switch from i386 to amd64. signature.asc Description: Digital signature
Crossgrade to Amd64
I followed the instructions on http://wiki.debian.org/FAQsFromDebianUser#Are_cross-grades_possible Needed one more :amd64 package which I installed, then installed the dpkg- amd64 successfully. This worked. Rebooted to the 64-bit kernel, everything OK. Did apt-get update. So now I have 90+ broken packages. If I fix, it will simply (re-)install dpkg, putting me back on i386. Then, (with no new update), have 20+ broken packages (:amd64) which the fix will simply remove. Most of these have been around a while and were never flagged or gave problems (since simply never used). So how do I complete the changeover? Or do I simply reinstall the old dpkg and apt-get update, then hopefully back where I started, await updated crossgrade procedure?

A full cross-grade can only work if all relevant packages have been converted to multi-arch. The alternative is to remove the i386 package and install the amd64 version instead. Depending on your set of packages it may be simpler to just reinstall ;) Kind regards, Andrei -- http://wiki.debian.org/FAQsFromDebianUser Offtopic discussions among Debian users and developers: http://lists.alioth.debian.org/mailman/listinfo/d-community-offtopic signature.asc Description: Digital signature

A full cross-grade can only work if all relevant packages have been converted to multi-arch. Well, it's only really necessary for the essential packages and their dependencies. IIRC the only package that fails in Wheezy is libmount1¹, meaning that mount will be temporarily broken during the crossgrade. The alternative is to remove the i386 package and install the amd64 version instead. This is really the only thing possible with apt since it does not support crossgrades at all. However, it should be possible to do a crossgrade with dpkg alone, by fetching the amd64 version of all installed i386 packages (if there is one), putting them into a dedicated directory and running dpkg -iR on it several times (dpkg will likely spew lots of errors in the process). In a minimal chroot this worked quite well for me, but if there are a large number of perl and python packages installed I wouldn't be so sure that it succeeds eventually. Depending on your set of packages it may be simpler to just reinstall ;) Currently I would recommend that. The procedure outlined above is not for the faint of the heart, and you better have a backup available in case it fails.
