Just had the same issue on an aws instance running ubuntu 18.04.4
(GNU/Linux 5.3.0-1028-aws x86_64)
It bricked that instance when I rebooted it. I did run apt a few days
ago and today noticed the system was asking for a reboot, which I did
after business hours.
Now I can only see the screenshot, it says:
error: symbol `grub_calloc´ not found.
Entering rescue mode...
grub rescue> _
Seems to be a prompt, I cannot interact with.
The instance monitoring graph on CPU use is up to 49% since this happened. Is
it actually trying to fix itself?
>From what I've read the only way back for that one would be to launch
another instance an manually recreate the messed config on the bricked
one's volume. Is it the case?
Luckily enough I had an almost exact copy of that instance running
already, so I just redirected traffic. But this second instance seems to
be in the same stage, it is asking for a reboot and I have no idea if I
can do that. Can anyone point me to the direction of what I should do to
fix it?
