Hi Bug still present in 18.04. I make my install from netboot(http://archive.ubuntu.com/ubuntu/dists/bionic/main/installer-amd64/current/images/netboot/)
os-prober version is 1.72 in the target. And I use a preseed file: (https://pastebin.com/6jB5xVJT) After few try and different partition and grub configuration, I have all the time the same problem. The solution in the debian (https://bugs.debian.org/cgi- bin/bugreport.cgi?bug=853187) help to pas the problem, but preseed is to a automatic install, I don't found a way to override the bug without do it manually. If you have any idea ? ** Bug watch added: Debian Bug tracker #853187 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=853187 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1663645 Title: Installation hangs at 66% "Installing GRUB boot loader" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/os-prober/+bug/1663645/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
