Hi! I have been testing the installation of GRUB in debian-installer on disks with GPT labels. Unfortunately, that doesn't work as grub-install complains it cannot find the filesystem for /dev/vdiska1. Looking at the partition table with parted, it seems that the actual problem is a corrupted GPT partition table (see below). Since a new partition table is created by debian-installer, it shouldn't be corrupted at this point. So, I'm wondering what problem we are running into. I will have a look at the partman-partitioning source code but if someone wants to perform their own tests in the meantime, the test installation image can be found here: > https://people.debian.org/~glaubitz/debian-cd/debian-10.0-sparc64-NETINST-1.iso Adrian ============================================================================= root@debian:/# parted /dev/vdiska GNU Parted 3.2 Using /dev/vdiska Welcome to GNU Parted!
