Status changed to 'Confirmed' because the bug affects multiple users.

[Phillip Susi (psusi)]

Please attach your /boot/grub/grub.cfg file.

[meteor (604733992-qq)]

I have the same error.
Can you see my /boot/grub/grub.cfg file?

[Phillip Susi (psusi)]

Please try sudo apt-get install --reinstall grub-common and sudo update-grub.

[meteor (604733992-qq)]

I tried, but no use.
Still have the error.

[Phillip Susi (psusi)]

Can you attach your /etc/grub.d/10_linux file?

[meteor (604733992-qq)]

I do not have the 10_linux file.
I only have 10_linux_proxy file.

meteor@Meteor:/etc/grub.d$ ls
00_header 10_linux_proxy bin README
05_debian_theme 30_os-prober proxifiedScripts

[Phillip Susi (psusi)]

That file is not part of Ubuntu. What does apt-cache policy grub-common show?

[meteor (604733992-qq)]

meteor@Meteor:~$ apt-cache policy grub-common

10_linux_proxy seems to be a custom config file. If you don't know why it is there, you should remove it, and reinstall grub-common, which should replace 10_linux.

[meteor (604733992-qq)]

Do you mean that I do like this?
rm 10_linux_proxy
sudo apt-get install --reinstall grub-common
sudo update-grub.

[Phillip Susi (psusi)]

Yes.

[meteor (604733992-qq)]

I remove 10_linux_proxy this file.
But below command can not help to create this file.
sudo apt-get install --reinstall grub-common
sudo update-grub.

Then I can only use boot-repair software to reinstall GRUB.
Now it is OK.
No error message anymore.

[Phillip Susi (psusi)]

I thought you said this was resolved? What seems to be the problem now? Did you remove the custom config file as I asked?
