Comment 5 for bug 162630

The symlink for liblzo.so.1 is clearly wrong, as it should be pointing to liblzo.so.1.0.0:
lrwxrwxrwx 1 root root 15 2007-11-21 23:34 /usr/lib32/liblzo.so.1 -> liblzo.so.1.0.0 (also from ia32-libs version 2.1ubuntu3).

Unfortunately Ubuntu does not seem to have any package which provides a file liblzu.so.1, so it is unclear what is causing this problem.

Does this problem only occur with updates (and I assume you use update-manager for these)? Or does it also happen when you do sudo apt-get update and sudo apt-get upgrade from a terminal window?
Does it happen when you install a package through synaptic?
