I have tried to install the package krita-animation-testing via the instructions here which tells me to add a repository, update my package lists, and install the package. When I try to install the package I get this error:
The following packages have unmet dependencies:
krita-animation-testing : Depends: libgsl0ldbl (>= 1.9) but it is not installable
Recommends: create-resources but it is not going to be installed
Recommends: kde-style-oxygen but it is not going to be installed or
kde-style-oxygen-qt4 but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
To my knowledge this is simply saying that the dependency, libgsl0dbl, does not exist in the repositories. I am running Xubuntu, and I got the same error on Gallium OS.
I do not understand why this does not work because the instructions are specifically for Ubuntu and I'm using 16.04-based OSs. Is Xubuntu missing a repository that I can add or can I get this dependency from somewhere else?
