Package: dpkg Version: 1.18.6 Severity: important After upgrading from version 1.18.4 to 1.18.6, dpkg binary executables will not run on my system anymore. They will crash with an "illegal instruction" error. In fact, apt-get aborts during the upgrade because dpkg crashes after unpacking the new version of itself. Of course, this leaves the system with a broken dpkg so I can't downgrade to the previous version either (at least not without doing things by hand with the help of a healthy system).
