> True indeed, but package 'libmmdb2-0-dbg' was never uploaded neither to unstable nor to testing. Therefore, there is no use of 'Breaks' or 'Replaces' indication for it. Or do I miss something? It was uploaded into experimental. There is no Break or Replaces for this one because the name of the library changed. all files are different for the -dev and the libnames. Cheers Frederic
