Hi Giuseppe, the DSA are untranslatable on our web page, yes. We did that on purpose. First, these announcements are very technical information, not intended for end users. End users just want to upgrade their system and know if all packages are up to date. That's why we think most people that are interested in these security information understand english. Second, there are automatic translation services, that can easily translate those pages.
Adding PO support may be possible (you have to change the perl script), but I will not spend time into it, because IMO there are more important parts on the web page I like to improve. -- best regards Thomas
