Comment 51 for bug 831768

I tried to install aptitude_0.6.6-1_amd64.deb from debian/unstable today on Precise, but that doesn't work because of a missing dependency to libapt-pkg4.10, which is provided by apt 0.8.15.10 in Debian, but installing that would be a downgrade from the Precise apt 0.8.16~exp12ubuntu6. So I gave up. :(
