I had a weird error on my machine. The file containing the text of the general public license /usr/doc/copyright/GPL is gone, the file /usr/doc/copyright/LGPL is still there. I don't know what did delete this file but I 'm quite sure I didn't do it manually. Is some package perhaps hardlinking/softlinking to this file and when removing the package the GPL is removed too? Am I missing more files on my system? How to check.? Erick
