Jeremy, thank you for the debdiff. I tried to apply it, but it does not build. First, I have downloaded the current version on Zesty and applied the debdiff to it. This worked perfectly, but when trying to build, the patches in debian/patches/series do not apply. What did I do wrong? Here is the console output: till@till-x1carbon:~/ubuntu/system-config-printer/zesty$ apt-get source system-config-printerter Reading package lists...
