How to update-grub

18 July 2019, 15:37:50

Hello. New Artix user here. I installed Artix artix-lxqt-openrc-20181008-x86_64.iso, upgraded, and manually installed kde starting with plasma-desktop package. All is well with my system.

I need to modify the grub config file at /etc/default/grub. I have made my changes, but cant figure out how to update grub. What I normally do is enter update-grub and this will use the grub conf file to update /boot/grub/grub.cfg. But there is no update-grub on my system.

Grub is at version 2:2.04-1:

Code: [Select]


[[email protected] ~]$ pacman -Q grub
grub 2:2.04-1

No update-grub:

Code: [Select]

[[email protected] ~]$ sudo whereis grub
[sudo] password for dxrobertson: 
grub: /usr/lib/grub /etc/grub.d /usr/share/grub /usr/share/info/grub.info.gz
[[email protected] ~]$ sudo whereis update-grub
update-grub:
[[email protected] ~]$

Am I missing update-grub, or does Artix use a different method to update?

Thanks in advance.

I have seen guides on internet that uses this command set for grub update
Try this

Code: [Select]

# pacman -S grub os-prober
# grub-install --recheck /dev/sda
# grub-mkconfig -o /boot/grub/grub.cfg

Thanks @cynicfm!

I recall using grub-mkconfig in the past but had forgotten about it. All I needed was to run grub-mkconfig, didn t need grub-install.

Code: [Select]


grub-mkconfig -o /boot/grub/grub.cfg

BTW: Since I always had trouble because of the missing auto scan function in GRUB2 (e.g. after updating a kernel or replacing the root filesystem), I replaced it tonight with rEFInd. For now, everything works fine.

Yes, grub update success; thanks again!

To clarify and help others coming from other distros that may encounter lack of update-grub in Artix:

If you are used to entering:

Code: [Select]

update-grub

Enter this instead:

Code: [Select]

grub-mkconfig -o /boot/grub/grub.cfg
