I updated a 15.5 box to 15.6 via the "zypper dup" method referenced at https://en.opensuse.org/SDB:System_upgrade. #init 3 #sed -i 's/15.5/${releasever}/g' /etc/zypp/repos.d/*.repo #zypper --releasever=15.6 refresh #zypper --releasever=15.6 dup No errors. Then rebooted. It hangs at grub: GRUB loading. Welcome to GRUB! error: ../../grub=core/kern/dl.c:380:symbol 'grub_verify_string" not found. Entering rescue mode... grub rescue> So I tried to reinstall grub from rescue mode of the install media. #fdisk -l /dev/sda Disk /dev/sda: 55.9 GiB, 60022480896 bytes, 117231408 sectors Disk model: INTEL SSDSC2CW06 Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: dos Disk identifier: 0x000ab703 Device Boot Start End Sectors Size Id Type /dev/sda1 2048 2105343 2103296 1G 83 Linux /dev/sda2 2105344 10489855 8384512 4G 82 Linux swap / Solaris /dev/sda3 * 10489856 117229567 106739712 50.9G 83 Linux tty1:rescue:~ #grub2-install --force /dev/sda ( I tried sda, sda1, and sda3) Installing for i386 platform. grub2-install: error: failed to get cononical path of 'tmpfs' How to fix this?
