Good Morning! I'm having trouble installing Jessie updates via Package Updater. The dialogue window says "downloading packages", but when I click "install" and authenticate, a message pops up saying: Failed to process request. Details: E: http://ftp.de.debian.org/debian/ jessie/main file i386 1:5.22+15-1 is not (yet) available (404 Not Found) What can I do about it? Greetings Frank
