Unable to launch Grub-Customizer

[Slyvester]

Hi everyone,

Everytime I try to launch grub-customizer via terminal : sudo grub-customizer,  I get no result but this weard message in terminal :

slyvester@slyvester-desktop:~$ sudo grub-customizer

(grub-customizer:1606): Gtk-WARNING **: Theme parsing error: gtk-widgets.css:2:19: Theming engine 'adwaita' not found

(grub-customizer:1606): Gtk-WARNING **: Invalid input string

I know I'm just a click away to the solution .. I've tried to find an answer on the web, but no dice ! Any help would be highly appreciated !

Did you try to launch it from menu?

[Slyvester]

Yes idead Pavroo. The password is requested and then ... nothing !

[pavroo]

I don't know the app at all, couse I never use it.
I suggest to report it to:
https://bugs.launchpad.net/grub-customizer

Everything what you need to do with grub, can be done via a terminal emulator.
What exactly you'd like to do?

[Slyvester]

My grub-customizer is there somewhere - hidden I guess - because when I type : sudo leafpad /etc/default/grub in terminal, I get this :

# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.

One thing I forget to tell you is that I use a MultiBoot with three different OS on this computer : Sparkylinux + Watt OS R8 + Lubuntu 14.04.2. I don't know if this is matters or not ...

[pavroo]

It looks ok, the question is: what you need to do/change in grub settings?

[Slyvester]

i'm just trying to get to the Main-Screen of Grub-Customizer and get to the general settings of grub-customizer. From there I can/could tweak the different kernels of my three different OS. Check out this please : http://www.linuxcore.fr/2013/06/grub-customizer/
(see Interface de grub-customizer).

I've done this many times on other different distros and this in order to manage the kernels and the distros themselves. I'm working my way to find the path via sudo leafpad /... If you 've got an idea ?

[Slyvester]

Of course, I could try to change my settings via /boot/grub/grub.cfg .. Crazy, isn't it ? Now you understand why i want to use the graphical tool : Grub-Customizer, its General settings thanks to the Main Sreen.

[pavroo]

Ok, I get it.
Managing all the Linux distros in grub list can be done editing the file:

Code Select Expand

/etc/grub.d/10_linux
But it is not recommended to edit it manually.
It's better to add your changes to file:

Code Select Expand

/etc/grub.d/40_custom
Anyway, the grub-customizer deb package has been built for Ubuntu not Debian and I suggest to report it to the app developer.

[GeneC]

Grub customizer works fine here, and has for many months..?
Where did you get yours from?

Mine

gene@sparky:~$  apt-cache policy grub-customizer

Hi GeneC,

I'm back only now because I first wanted to update & upgrade (sudo apt-get update && sudo apt-get dist-upgrade = sudo update-grub) my two other distros (Lubuntu 14.01.1 + Watt OS R-8). By the way, I tried via terminal : sudo grub-customizer which launched twice the graphical-tool on the two of them. Now I'm back to back to Sparkylinux, but again no dice. I just uninstalled & reinstalled - via Synaptic - Grub-Customizer but I still get the same message on the terminal:
slyvester@slyvester-desktop:~$ sudo grub-customizer

(grub-customizer:8609): Gtk-WARNING **: Theme parsing error: gtk-widgets.css:2:19: Theming engine 'adwaita' not found

(grub-customizer:8609): Gtk-WARNING **: Invalid input string

@GeneC : thanks a lot, but I've got exactly the same apt-cache policy as you ...

@Pavroo :  yes, I can manage my Linux distros in grub list by editing the file: sudo leafpad /etc/grub.d/10_linux but this is too dangerous. One mistake in that file can cause a disaster : no more boot at all !
You asked me : what you need to do/change in grub settings? Well, I kinda get to thinking that I don't need Grub-Customizer so bad.
If I really need it, I can always change the major boot from another distro Linux with : sudo os-prober. I'll be then able to launch Grub-Customizer from that new "os-prober distro". I must say that using too many diferent Linux distributions (7 or 8?) can only lead to problems. I get telling myself I should delete a few of them but ...
I was wondering Pavroo, are you the only one who takes care of SparkyLinux ? Because if it is so, let me tell you that I respect you and admire you for all the things you do. This particular SparkyLinux distribution is simply great and remains one of my beloved ones if not my favourite among all others. Thanks again to you !

Actually this is what I do.  I  presently have a 3 distro multi-boot and have grub-customizer only on one.  I always boot from that distro, and dont need it on others.

To boot from that distro (and use its grub and grub-customizer) run this command from that distro.

Code Select Expand

sudo grub-install /dev/sda

PS:
I did not realize that  grub-customizer in the repo..  Please disregard my link...;)

[Slyvester]

I just tried the command : "sudo grub-install /dev/sda" but again no change because that's the way it was supposed to be. Now, you should use : sudo os-prober on any distro to make "grub-customizer" the ruler of your Multiboot from the distribution of your choice.
The only thing that still puzzles me is the version of my grub-customizer that I just reinstalled : GNU grub version 2.02 beta 2-22 ...

[pavroo]

GNU grub version 2.02 beta 2-22

It's the latest version now in Debian repos.
Debian Jessie become stable tomorrow (hope so) and the beta version of Grub will be installed as default, I think.

Hello Pavroo,

Did you read what I wrote yesterday ? It's all about you !

I was wondering Pavroo, are you the only one who takes care of SparkyLinux ? Because if it is so, let me tell you that I respect you and admire you for all the things you do. This particular SparkyLinux distribution is simply great and remains one of my beloved ones if not my favourite among all others. Thanks again to you !
