Hello, New unsigned grub packages were introduced in grub2 (2.12-3). Calamares tries to pull these in during the install. If there is no internet connection, this fails and the installer stops with an error. However, if an internet connection exists they are pulled from the repos and the install succeeds. I think it is best if the live images continue to function without an internet connection. I was using the XFCE weekly live image from this past monday. Thanks. Brandon
