libgtkmm-3.0-dev (unmet dependencies)

[MueDominik]

Hello

Due to a bug in the Linux 4.13 kernel, I recently switched from Ubuntu 17.10 to Debian 9.
Since I have a dual-boot setup, I'd like to customize the GRUB 2 boot loader to boot up Windows 10 by default (making it the default entry). Until now I've done this by using the package "grub-customizer".
So I decided to install the previously mentioned package on Debian Stretch as well. While installing the package "libgtkmm-3.0-dev", as mentioned in almost any guide [1] [2], I encountered the following problem:

Code: Select all

muedominik@debian:~$ sudo apt install libgtkmm-3.0-dev
Reading package lists... Done

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 libgtkmm-3.0-dev : Depends: libgtk-3-dev (>= 3.22.0) but it is not going to be installed
                    Depends: libcairomm-1.0-dev (>= 1.12.0) but it is not going to be installed
                    Depends: libpangomm-1.4-dev (>= 2.38.2) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

So I tried to install the package "libgtk-3-dev" which lead to the following:

Code: Select all

muedominik@debian:~$ sudo apt install libgtk-3-dev

The following packages have unmet dependencies:
 libgtk-3-dev : Depends: libpango1.0-dev (>= 1.37.3) but it is not going to be installed
                Depends: libcairo2-dev (>= 1.14.0) but it is not going to be installed
                Depends: libfontconfig1-dev but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

Which lead me to this:

Code: Select all

muedominik@debian:~$ sudo apt install libpango1.0-dev
[...]

The following packages have unmet dependencies:
 libpango1.0-dev : Depends: libcairo2-dev (>= 1.12.10) but it is not going to be installed
                   Depends: libfontconfig1-dev (>= 2.10.91) but it is not going to be installed
                   Depends: libxft-dev but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

This just keeps going on... I just want to install the package "libgtkmm-3.0-dev" so that I'm able to install "grub-customizer".
I hope someone can tell me what I'm doing wrong here.

Thank you for any help you can provide.

You are aware that you can do that by changing a single line in a single file and running a single command afterwards, right?

That "grub-customizer" nonsense is not needed at all.

Looks like I've already created a "FrankenDebian" by adding "sid" to install the latest release of Mozilla Firefox (Quantum).

Yes I'm aware of the fact that I can change the file "/etc/default/grub" an then run the command "update-grub". I'm most likely going to do it like that, since I've invested enough time into this problem already...

But I would still like to know why I can't install the "libgtkmm-3.0-dev" package.

why I can't install the "libgtkmm-3.0-dev" package.

I've already created a "FrankenDebian" by adding "sid"

^ These two facts are intimately related

Looks like that pinning "tutorial" was completely FOS, eh?

And those guides have their heads up their butts, anyway. The best way is to rebuild deb packages on Debian from the PPA sources, but you can't build anything with a broken system...and Firefox was the worst program to break your system for, too. There are several ways to get the current Firefox on Stretch or Jessie without adding the upstream repositories.

https://wiki.debian.org/CreatePackageFromPPA

Though that PPA source has some janky parts in the build procedure that certainly be improved...dpatch and debhelper 7, really? (fires up text editor)
