Bug Description
On last system upgrade I dropped on a Grub prompt .
After hours spent on internet from my smartphone, I managed to boot on my zroot fs with the following procedure :
NOTE : the following errors have been OCR-ized from pictures taken with smartphone, and most typos have been fixed (please forgive me for those remaining)
```
grub> set root=(hd1.gpt3)
grub> linux /BOOT/ubuntu.
grub> initrd /BOOT/ubuntu.
grub> boot
```
I don't know if it's related , but errors start appearing while installing new packages :
```
Processing triggers for man-db (2.9.1-1) ...
ZSys is adding automatic system snapshot to GRUB menu
Error Service took too long to respond. Disconnecting client
```
I would like to fix this boot error and any attempts I made with grub commands failed to this previous prompt.
Thank you for any hint or track you could provide.
Regards,
