Besides that, I got: dpkg-gensymbols: warning: new libraries appeared in the symbols file: libobjc_gc.so.2 That are the only symbols warnings I got. The changes file is generated, now I can upload to unstable for the first time. Thanks for the quick responses/uploads, this helped immensely. I’ll leave the symbols stuff to you as I don’t know about them, from my side this can be closed now.
