Thank you for this useful feedback, it contains some suggestions that I can work with. I am not sure about not failing the installation when the download failed. The package is then not fully operational, so failing the package installation seems appropriate - then the packaging system will reprompt the user to complete the package configuration upon its next run. It also means that dependencies on the package are not considered to be met, which is correct as the fonts they depend on are not yet present. What do you think? Increasing the debconf verbosity may be a useful idea, and I will see what I can do about that. Probably it will take a little time if we have to add or make changes to some of the strings, to get the translations back in order. cheers, Thijs
