package libgl1-mesa-dri 17.0.7-0ubuntu0.16.04.1 failed to install/upgrade: symbolic link '/usr/share/doc/libgl1-mesa-dri/changelog.Debian.gz' size has changed from 80 to 36

Installing packages fails because symlinks have a different size than expected.
What works is manually removing the links, but I suppose that dpkg should not worry about symlinks if they are working.
As this error is summing up, I don't want to manually delete all links,
therefore I just start deleting all of them
e.g.:
  rm /usr/share/doc/*/changelog.*gz
  rm /usr/share/doc/*/NEWS.*gz

in a script.

Here is a reinstallation call
