Bug#1095249: libgtk-3-0t64: file '/usr/lib/aarch64-linux-gnu/libgtk-3-0/gtk-query-immodules-3.0' in both package libgtk-3-0t64 and libgtk-3-0.

[Andrew Maier]

Hello,

Thanks for all these pointers.

For my Raspis, I usually install a Debian (not Rasbian) stable image and then move from stable to testing. I initially had the error when moving from stable to testing and assumed this would be a transitory packaging error. Only when this was not resolved with updates I thought that this was a bug

Looking at the apt sources, I have now discovered that there is a Rasbian source in /etc/apt/sources.lists.d, which has a reference to Rasbian, which I do not recall having added myself. So, the image I am using appears to be not a “pure” Debian image, and this might create the problems I have had.

I will try to have a look and see if the original image contains the Rasbian entry or if this is entirely my fault.

Apologies for all the mess I am creating, but if the apt source is in the original image, I will follow up with Rasbian. Please consider this a stupid user error and not a Debian bug. My only hope is that I have learned something in the process. 

Thanks again,

Andrew
