Fairly catastrophic failure here - the migration failed on my online VPS: [grub-install failure for /dev/vda4 (full log)](https://paste.yunohost.org/raw/pogafifive). Now, when I go to try to fix the issue, none of my admin users have sudo permissions anymore, and I cannot log in with root (neither via SSH or directly using the VNC function from my VPS provider). I’m a bit concerned here as this is a large media hosting VPS for which I cannot afford a backup. Any help appreciated!

Note: the log is from my second attempt to migrate - the migration failed earlier initially with the same error.

Update:

- Fixed the sudo issue by [resetting the root password](https://www.tecmint.com/reset-forgotten-root-password-in-debian/) and adding admin users to the sudo group.
- Ran `sudo DEBIAN_FRONTEND=dialog dpkg --configure grub-pc` per log: received a scary warning saying that GRUB had failed to install on /dev/vda4 and asked whether I would like to continue knowing that my machine may not boot. I selected `yes` as I was fairly certain that vda4 wasn’t my boot device, and the logs had indicated that GRUB had installed succesfully to /dev/vda2, which is my boot device according to the output of `cat /etc/fstab/`.
- …and it survived a reboot. Calibreweb is dead now with: `ModuleNotFoundError: No module named 'flask'`
- Calibreweb fixed with `yunohost app upgrade --force calibreweb`
