Migration to yunohost 12 : grub-install fails

[jeremy1]

What type of hardware are you using: VPS bought online
What YunoHost version are you running: 11.3.0.2
How are you able to access your server: SSH
Are you in a special context or did you perform specific tweaking on your YunoHost instance ?: I installed crowdsec (does not seams relevant here)

Describe your issue

Hello all,

While performing the migration to Yunohost 12 (sudo yunohost tools migrations run --accept-disclaimer), I got the following error :

grub-install: error: unable to identify a filesystem in hostdisk//dev/sda; safety check can’t be performed.

Nobody seems to have had this problem yet. Internet tells me that it might be a BIOS issue ?.. How could it be related ?

Thanks for your input

Cheers

P.S.: Looking at 🚀 YunoHost 12.0 (Bookworm) release / Sortie de YunoHost 12.0 (Bookworm) - #143 by Aleks currently … I will update this post if I find anything interesting

I followed the instructions in the comments of the main announcement post:
apt full-upgrade --dry-run
then
apt full-upgrade

in order to install grub-install myself, as it actually waits for a configuration option from the user running it from terminal allowed me to provide grub-install with the demanded choices/options (through interactive inputs in terminal).

Once the grub-install installation finished, I finished the migration.

(side-note : grub-install did NOT installed well, and therefore it told me that I might not be able to restart my server I live dangerously)

Hope it will help anyone !

And many thanks for the amazing work, Yunohost team !!! (including helpers in this forum !!)
