The new Grub configuration cannot be saved

[Roger Peartree]

In Linux Mint 18 "Sarah" Cinnamon x64 I get the following error when trying to save my customized version of grub.cfg:
<code>failed running 'grub-mkconfig -o "/boot/grub/grub.cfg"' output:

I'm attaching the text above, the grub.cfg file and the grub.cfg.new files as a .zip file
Any help with this bug will be much appreciated, thanks.

It's the old known problem of /etc/grub.d/05_debian_theme which is not quoting the background image path in any way. It's not a bug of grub customizer, it's a bug of debians version of grub2.

Make sure your selected background image path has no spaces, no & and no '.

Another problem that will come up:
There's a /etc/grub.d/06_mint_theme. This overwrites selected colors. So better remove it or disable its "script code" entry using grub customizer (previously show these at View -> Show placeholders).

Many thanks. It's fixed now. I removed the mint_theme_06 placeholders (yes
there were 2!) from Grub Customizer and to make sure I went to /etc/grub.d
and renamed that file with a bak extension. No need to touch
debian_theme_05 because you don't say to remove it and I'm not sure if it's
needed. Also gave a simpler path to background image:
/usr/share/images/grub/ImageNameNoSpaces.tga. This /images folder doesn't
exist by default so I created it and also created /grub inside that one. I
found out by looking at other people's themes that you should convert your
background image to the tga format (just use GIMP). That way it will stay
there. Of course, until the next Grub update :-)
Many thanks again for your precious help and can't thank you enough for
your amazing work.
