sudo update-grub fails

[ajgreeny]

I have just installed Xubuntu 24.04 LTS "Noble Numbat" - Daily amd64 (20240326) then edited the grub config and run sudo update-grub but it is failing with output

andrew@Xubu26Mar:~$ sudo update-grub
[sudo] password for andrew: 
Sourcing file `/etc/default/grub'
/usr/sbin/grub-mkconfig: 33: /etc/default/grub: want: not found

I rebooted and tried again but no go!
Here's the content of /etc/default/grub

andrew@Xubu26Mar:~$ cat /etc/default/grub

What happens if you delete the ` from the end of

GRUB_DISTRIBUTOR="Xubuntu26March"`

Oh gosh!!!

I had not even noticed that the ' was left behind after editing the file.
I'm not on he machine at the moment but will cerainly check tomorrow at some point and report back.

Thanks for noticing that error; I hope it is the answer!

I realised after saying I would report back on this that I had already deleted the VM of Xubuntu that had this problem.
Its successor installed this evening, 28 March from an iso also dated 28 March is working as expected.

However, when is the "quiet splash" option going to be the default?
All iso archives of Xubuntu at present don't have that enabled so it shows the scrolling boot text until that /etc/default/grub file is edited and sudo update-grub is run.
You still end up with the full GUI but it's still unnecessary and a bit annoying!

Please update the OP title with a [SOLVED] prefix.

Thanks!

Please do not attempt to moderate posts or threads on Ububtu Forum; leave it to staff only to do this!

And no!
I shall not mark this thread as solved as I still don't know if it has been.

As I said above, I deleted the VM of that system before I could test it so a solution is not yet possible.
Having edited that file in another system where the update-grub worked as expected, adding the extra ' after the required " of my DISTRIBUTION edit I did not see the problem repeated so I suspect some other cause yet to be ascertained.

Fair enough... but I wasn't trying to moderate you...
I was looking for info about something related to GRUB and your last post reads to me as "oops... now it is working"... a waste of time... and now again.... a waste of my time... take care and have a good one tho...

"Patience is truly a virtue."

Do not ask for things to test that, or you may get examples to practice it...

I do understand. I try to err towards being courteous and empathetic. We all live here together.
