grub2 fails to install on md0 (preseed lvm over raid) partman-auto-raid bug

It seems I'm hitting the same problem. Could you post your preseed configuration related to raid and lvm ?

Status changed to 'Confirmed' because the bug affects multiple users.

i fixed the bug by adding this:

d-i partman/early_command string \
   sed -i 's/\/dev\/md\$MD_NUM/\/dev\/md\/$MD_NUM/g' /bin/auto-raidcfg; \
   sed -i 's/\/dev\/md\$raidnum/\/dev\/md\/$raidnum/g'
/lib/partman/display.d/55initial_auto_raid_fs
