Hi Darko, Thank you very much for writing this up for me mate!
I'm not sure I even need this as I'm just an average Net user? My system is 32 bit but I think I installed this maybe when thinking of doing a web site??? I tried what you wrote but keep getting errors like it doesn't exist, though I'm prompted everyday to update and returns a failure. Here's the output after the first command: Reading package lists... Done Building dependency tree Reading state information... Done The following packages were automatically installed and are no longer required: python3.2 python3.2-minimal Use 'apt-get autoremove' to remove them. The following extra packages will be installed: libxml2 The following NEW packages will be installed: libxml2-dev The following packages will be upgraded: libxml2 1 upgraded, 1 newly installed, 0 to remove and 5 not upgraded. Failed to exec method /usr/lib/apt/methods/ E: Method has died unexpectedly! E: Sub-process returned an error code (100) E: Method /usr/lib/apt/methods/ did not start correctly Second command output: mv: cannot stat `/usr/bin/xml2-config': No such file or directory and so on it goes pretty much the same from there. Please see the screenshots from the Update Center too. I'm really grateful for your help with this mate, I tried to follow the links to rectify them all but don't have a clue what to do with the files once downloaded. Cheers mate!

The problem is caused by the sed call in debian/rules says "usr/lib/<tripple>", while it wasn't like that in xml2-config script itself. [Impact] libxml2-dev is not M-A co-installable [Development Fix] libxml2 version 2.7.8.dfsg-9 in Debian Sid [Stable Fix] Change required is trivial, in debian/rules: - sed -i -e 's,/usr/lib/$(DEB_HOST_MULTIARCH),/usr/lib,' debian/libxml2-dev/usr/bin/xml2-config + sed -i -e 's,/lib/$(DEB_HOST_MULTIARCH),/lib,' debian/libxml2-dev/usr/bin/xml2-config [Test Case] Enable M-A in testing environment (amd64 for instance), and try to install both libxml2-dev:i386 and libxml2-dev:amd64 which were newly built with the mentioned patch. If the action failed with something like './usr/bin/xml2-config' is different from the same file on the system, then the bug was not fixed. [Regression Potential] xml2-config reports the libdir is /usr/lib, while the actual ones are /usr/lib/<triplets>. This might break applications whose build system can't find libraries correctly in the previous path but relies on xml2-config's output. I recommend to use pkg-config instead of this script.
