Comment 3 for bug 2052878

Well, as this happened to me for the third time since I installed the machine, I'm in doubt I deleted the file intentionally.

I found the file was missing since 2024-02-04T07:34:56Z.

Well, actually, this other bug: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1879466 seems to be linked with this recent failure of mine because of the root cause was missing /etc/default/grub.

I restored the file from snapshot and will watch its presence closely.

Thanks a lot for your time!
