I manage one 16.10 box and this will the situation when 17.04 is fully released. They don’t have the option staying on the LTS because LibreOffice acts funny on older versions. It has a simple Luks install in case nothing falls into the wrong hands. When I tested the alpha build on my netbook with the Luks option, it failed miserably. Their machine however is indeed 64-bit. Will the upgrade process be simple and (theoretically) with minimal errors? I’m looking for people who have tested this – especially the ones who had Luks pre-installed because I think this would be the confounding issue as it’s not installed on the majority of machines.
