I suggested _removing_ those devices and trying again -- not making sure that GRUB was able to see them correctly. If they're backup drives, as the names suggest, then temporary removal should not hurt, right? -- Liam Proven - Profile: https://about.me/liamproven Email: lpro...@cix.co.uk - Google Mail/Hangouts/Plus: lpro...@gmail.com Twitter/Facebook/Flickr: lproven - Skype/LinkedIn: liamproven UK: +44 7939-087884 - ČR (+ WhatsApp/Telegram/Signal): +420 702 829 053 -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.ubuntu.com/UKTeam/

[ubuntu-uk] Can't update grub
I've tried asking this questions in numerous other places and so far I've had no response, so I'm hoping someone here will be able to help. I rebooted my server last week and when I tried to remove old kernels it was stopping when trying to update grub. I ran update-grub2 on its own and I get: Generating grub configuration file ... grub-probe: error: not a directory. fdisk -l shows: Disk /dev/sda: 111.8 GiB, 120034123776 bytes, 234441648 sectors 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: 0x31337774 Device Boot Start End Sectors Size Id Type /dev/sda1 * 2048 52430847 52428800 25G 83 Linux /dev/sda252430848 146802687 94371840 45G 83 Linux Running grub-probe -v -d /dev/sda1 produces this: grub-probe: info: adding `hd0' -> `/dev/sda' from device.map. grub-probe: info: adding `hd1' -> `/dev/sdb' from device.map. grub-probe: info: adding `hd2' -> `/dev/sdc' from device.map. grub-probe: info: adding `hd3' -> `/dev/sdd' from device.map. grub-probe: info: Cannot stat `/dev/disk/by-id/usb-Seagate_Backup+_Hub_BK_NA8TT3NB-0:0', skipping. grub-probe: info: Cannot stat `/dev/disk/by-id/usb-Seagate_Expansion_NA84KDR3-0:0', skipping. grub-probe: info: /dev/sda1 is present. grub-probe: info: Looking for /dev/sda1. grub-probe: info: /dev/sda is a parent of /dev/sda1. grub-probe: info: /dev/sda1 starts from 2048. grub-probe: info: opening the device hd0. grub-probe: info: drive = 0. grub-probe: info: the size of hd0 is 234441648. grub-probe: info: drive = 0. grub-probe: info: the size of hd0 is 234441648. grub-probe: info: Scanning for DISKFILTER devices on disk hd0. grub-probe: info: Scanning for mdraid1x devices on disk hd0. grub-probe: info: Scanning for mdraid09 devices on disk hd0. grub-probe: info: Scanning for mdraid09_be devices on disk hd0. grub-probe: info: Scanning for dmraid_nv devices on disk hd0. grub-probe: info: Scanning for ldm devices on disk hd0. grub-probe: info: scanning hd0 for LDM. grub-probe: info: no LDM signature found. grub-probe: info: Scanning for lvm devices on disk hd0. grub-probe: info: no LVM signature found. grub-probe: info: Scanning for DISKFILTER devices on disk hd0. grub-probe: info: Scanning for mdraid1x devices on disk hd0. grub-probe: info: Scanning for mdraid09 devices on disk hd0. grub-probe: info: Scanning for mdraid09_be devices on disk hd0. grub-probe: info: Scanning for dmraid_nv devices on disk hd0. grub-probe: info: Scanning for ldm devices on disk hd0. grub-probe: info: scanning hd0 for LDM. grub-probe: info: no LDM signature found. grub-probe: info: Scanning for lvm devices on disk hd0. grub-probe: info: no LVM signature found. grub-probe: info: Scanning for DISKFILTER devices on disk hd0. grub-probe: info: Scanning for mdraid1x devices on disk hd0. grub-probe: info: Scanning for mdraid09 devices on disk hd0. grub-probe: info: Scanning for mdraid09_be devices on disk hd0. grub-probe: info: Scanning for dmraid_nv devices on disk hd0. grub-probe: info: Scanning for ldm devices on disk hd0. grub-probe: info: scanning hd0 for LDM. grub-probe: info: no LDM signature found. grub-probe: info: Scanning for lvm devices on disk hd0. grub-probe: info: no LVM signature found. grub-probe: info: Scanning for DISKFILTER devices on disk hd0. grub-probe: info: Scanning for mdraid1x devices on disk hd0. grub-probe: info: Scanning for mdraid09 devices on disk hd0. grub-probe: info: Scanning for mdraid09_be devices on disk hd0. grub-probe: info: Scanning for dmraid_nv devices on disk hd0. grub-probe: info: Scanning for ldm devices on disk hd0. grub-probe: info: scanning hd0 for LDM. grub-probe: info: no LDM signature found. grub-probe: info: Scanning for lvm devices on disk hd0. grub-probe: info: no LVM signature found. grub-probe: info: Partition 0 starts from 2048. grub-probe: info: /dev/sda1 is present. grub-probe: info: Looking for /dev/sda1. grub-probe: info: /dev/sda is a parent of /dev/sda1. grub-probe: info: /dev/sda1 starts from 2048. grub-probe: info: opening the device hd0. grub-probe: info: drive = 0. grub-probe: info: the size of hd0 is 234441648. grub-probe: info: drive = 0. grub-probe: info: the size of hd0 is 234441648. grub-probe: info: Scanning for DISKFILTER devices on disk hd0. grub-probe: info: Scanning for mdraid1x devices on disk hd0. grub-probe: info: Scanning for mdraid09 devices on disk hd0. grub-probe: info: Scanning for mdraid09_be devices on disk hd0. grub-probe: info: Scanning for dmraid_nv devices on disk hd0. grub-probe: info: Scanning for ldm devices on disk hd0. grub-probe: info: scanning hd0 for LDM. grub-probe: info: no LDM signature found. grub-probe: info: Scanning for lvm devices on disk hd0. grub-probe: info: no LVM signature found. grub-probe: info: Scanning for DISKFILTER devices on disk hd0. grub-probe: info: Scanning for mdraid1x devices on disk hd0. grub-probe: info:
