libxml dependency problems

I tried upgrading libxml by way of the update-manager, but got

The following packages have unmet dependencies:

libxml2: Depends: libc6 (>= 2.15) but 2.15-0ubuntu10.7 is installed
         Depends: zlib1g (>= 1:1.2.3.3.dfsg) but 1:1.2.3.4.dfsg-3ubuntu4 is installed
libxml2-dbg: Depends: libxml2 (= 2.7.8.dfsg-5.1ubuntu4.11) but 2.7.8.dfsg-5.1ubuntu4.9 is installed
libxml2:i386: Depends: libc6 (>= 2.15) but 2.15-0ubuntu10.7 is installed
              Depends: zlib1g (>= 1:1.2.3.3.dfsg) but 1:1.2.3.4.dfsg-3ubuntu4 is installed

apt-get install -f returns an error (se below). Any advice for how to fix this?
