grub boot error : "symbol 'grub_calloc' not found

  • Hi there,

    after applying these Debian 10 security updates

    Code
    Get:1 http://deb.debian.org/debian-security buster/updates/main amd64 grub2-common amd64 2.02+dfsg1-20+deb10u2 [538 kB]
    Get:2 http://deb.debian.org/debian-security buster/updates/main amd64 grub-pc amd64 2.02+dfsg1-20+deb10u2 [131 kB]
    Get:3 http://deb.debian.org/debian-security buster/updates/main amd64 grub-pc-bin amd64 2.02+dfsg1-20+deb10u2 [903 kB]
    Get:4 http://deb.debian.org/debian-security buster/updates/main amd64 grub-common amd64 2.02+dfsg1-20+deb10u2 [2477 kB]

    concerning the GRUB boot loader on my OMV 5 system I made a reboot and the I got stuck within the boot loader with this message:

    error: symbol `grub_calloc' not found.

    Entering rescue mode...

    grub rescue>

    I suppose it has something to do with this Debian/Ubuntu Bug: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1889509

    However, has anyone a hint to solve this issue?

  • Hi there,

    Heise Developer Online, a IT news site in Germany made some sort of summary and status of the boot loader mess which happens on different Linux distributions. So I wonder which is the recommended way to fix the issue on an OMV system? Is it the Boot-Repair-Disk or the rather complicated way as described by the Ubuntu Security Team ? Any advice by the OMV experts would be highly appreciated.

    The issue here is not the boothole fix that Heise is referring to and is causing problems on RHEL/CentOS. It might be the issue from the Ubuntu team though. Either way, if you have a grub issue, you can always boot a Debian 10 ISO and it has an option to repair grub.
