Grub-customizer not installing in LL3.0

[m654321]

I have been using grub customizer (version 5.0.6-0ubuntu), an excellent tool for editing the grubscreen on my Dell laptop, where I have several operating systems installed. Grub customiser installed & worked smoothly with LL2.8, but I appear to have a glitch with it, when trying to install it on LL3.0.

When I attempt to install it in LL3.0, using gdebi package manager, I get the following feedback from gdebi and as a result gdebi is unable to proceed any further:

Code:

Error:
Dependency is not satisfiable: libatkmm-1.6-1 (>=2.22.1)

Confusingly, when I check synaptic package manager to see what version of libatkmm is installed, it appears that the libatkmm-1.6-1v5 package is there, and the version installed is 2.24.2-1, which is of course >2.22.1, listed above.

Any help in solving this is much appreciated, as always
