No certainly not. The issue here is if you have the wrong device configured to install grub on, it fails to install to it, but does not fail the upgrade process, and the disks grub loader does not match the grub on the boot partition.
Or you converted to raid1 manually or copied your disk and did not reconfigure grub. Running dpkg-reconfigure grub-pc should likely fix it, as it will ask you for the devices to install on again. This is not a problem on UEFI systems fwiw, as they do not use a small image in MBR and load the rest from /boot, but a single monolithic grub image in the ESP. Some more work is being done to harden this. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1889509 Title: grub boot error : "symbol 'grub_calloc' not found To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1889509/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
