Happy holidays!
Btw, the context:
- Ubuntu 22 on an Acer laptop;
- ubuntu live via USB stick, not CDROM;
- Secure Boot enabled and machine owner key set up.
The initial problem was that I did a regular software update (Software Updater, the gray icon with the circling arrows), then a restart – but this error message showed up, as the only text on a black screen, right after … first the vendor logo, then a while of a blinking cursor, then that:
Failed to start Samba NMB Daemon.
Not sure why samba is being necessary for booting, nor why it’s not working. Or why a regular software update can (nearly) brick your computer and ruin a holiday for you.
So I’ve launched ubuntu live from a USB stick that I still have luckily. There, I’ve ran boot-repair (Recommended Repair).
(UPDATE: the following block has now become just context. I doubt GRUB has anything to do with this. Let’s skip to the end of this post)

Neither do I understand why and what variables could not be set; nor what manual setup I am supposed to do; nor how or where I am supposed to make that boot change. It took me over a day of trying to decipher these cryptic instructions and warnings.
grub-install: warning: EFI variables cannot be set on this system.
grub-install: warning: You will have to complete the GRUB setup manually.
[…]
You can now reboot your computer.
Please do not forget to make your UEFI firmware boot on the Ubuntu 22.04.5 LTS entry (nvme0n1p1/efi/ubuntu/shimx64.efi file) !
I am a developer who uses vagrant, and in installing VMware, I was forced to set up a machine owner key. Is that why the variables failed to be set? I did not get any MOK prompt during this boot repair.
About that boot entry … are they talking about the boot order in the BIOS? There, I can see (1) linpus lite (2) ubuntu. “linpus lite” seems to be the correct one.
I tried rebooting. That samba error message is gone … but now the laptop is in a “boot and restart” loop, only getting past the Acer logo.
nvme0n1p1 is the one that has the shimx64.efi file – am I supposed to mount nvme0n1p1 or nvme0n1p2 now in order to update-grub? Why am I trying to do the same steps that boot-repair just did? Why don’t I have to also bind mount boot/ like I do for dev/ and others?

[…] Okay good, in writing this post, I could clarify a few things and we can skip several questions. “linpus lite” was not the correct priority.
Now I’m back to the initial samba NMB daemon error, though. I will keep looking myself, but I didn’t really find anything on this so far, which is probably how I ended up following ↑ the wrong lead.
Any help would be appreciated.
