apt-get / update-manager multiarch broke on libfreetype6 in Oneric today

[Darxus]

I just allowed update-manager to do an automatic upgrade. It failed. Now apt-get can't figure out what to do with it so my package management is all broken:

I had multiarch disabled. "foreign-architecture i386" in /etc/dpkg/dpkg.cfg.d/multiarch was commented out.

I uncommented it, and this problem went away.

This is all supposed to work without multi-arch, right?

Status changed to 'Confirmed' because the bug affects multiple users.

[reini (rrumberger)]

I experienced this as well, although I don't really consider it an important bug; if multiarch is disabled, there probably shouldn't be any foreign-arch packages installed, anyway.
To work around this bug, uninstall all foreign-arch (i386) packages.

Oneiric is dead since a while and that issue is not known with more recent package
