grub fails to update

[carlo]

hi all
i've noticed it's some kernel versions that grub isn't upgrading properly......
now i've removed grub customizer and tried to purge and resintall grub, but i always get the very same message:

Errore di sintassi alla riga 189
Errori di sintassi sono stati rilevati nel file di configurazione
di GRUB generato. Assicurarsi che non vi siano errori in
/etc/default/grub e /etc/grub.d/* o segnalare un bug allegando
il file /boot/grub/grub.cfg.new.

actually the file it tells me to attach is here: http://www.federproprietaabruzzo.it/Carlo/grub.cfg.new:

I don't know what installing and removing grub-customizer changed in grub config files, but it could.
I suggest reinstalling all installed grub files (should be 4 packs) and update grub manually after to check is still somenthing wrong.

[carlo]

i guess i've already done what you suggested, but the outcome would always be the same: check all of the /grub.d/ config files or report for bug

what if i try to install grub 1?

[pavroo]

I don't think it's a good idea.

Try: edit as root the file: /etc/default/grub and past inside, on the end of the file:

Code Select Expand

GRUB_DISABLE_SUBMENU=y
Then:

Code Select Expand

sudo update-grub

You have 8 Liquorix and 2 Debians kernels installed.
Do you need all of them?

Then:

sudo update-grub

alas it did the very same thing...

isn't it "the more the better"?

[carlo]

i've made an apt-get autoremove
it deleted some liquorix and maybe something from nvidia from what i could tell, then it sort of made update-grub many times, and i've noticed that this kind of messages

Errore di sintassi alla riga 567
appeared:
it says on line 567 there's a syntax error:
i've checked through /etc/defaults/grub and /etc/grub.d/* but no single file has so many lines
the only file to have enough lines is the /boot/grub/grub.cfg.new, which i'm going to upload again, just in case it change: http://www.federproprietaabruzzo.it/Carlo/grub.cfg.new2

[pavroo]

The line shows that it's about function gfxmode.

Looks like the file  /boot/grub/grub.cfg.new has been made by grub-customizer before.
Can you move the file (as root) out of the /boot/grub directory and update grub again?

[carlo]

i've move grub.cfg* to /tmp but the update grub command gives the very same output....

what is updaate-grub2 about?

[pavroo]

update-grub2 is a symlink to update-grub only so they run the same command

[carlo]

Actually grub totally failed to boot
Not sure whether to try to recover the files ive moved ir try a live grub install...

[pavroo]

i've move grub.cfg*

have you moved all grub.cfg* files out?

[carlo]

Yup

[pavroo]

That's why it's not useable now.
I said to move /boot/grub/grub.cfg.new file only.

[carlo]

hope i can find them when i'm back in office.....



just in case:
if i format is there any way to tell debian "pliiiiis install all the packages i had before i made anything wrong" in a short easy way?

[carlo]

i took the third path:

i've booted from sparky xfce, launched grub-repair:
it made me purge everything, then it reinstalled grub
with the latest debian and liquorix kernel besides linux mint
and boot works now
thank you
