ok, run:

sudo dpkg -P cairo-dock-plug-ins-integration; sudo apt-get --purge remove cairo-dock-core cairo-dock-data; sudo apt-get --purge autoremove

Should do it, rerun the command you ran earlier and it should now be removed

I tried that. the result

  -d Download only - do NOT install or unpack archives
  -s No-act. Perform ordering simulation
  -y Assume Yes to all queries and do not prompt
  -f Attempt to correct a system with broken dependencies in place
  -m Attempt to continue if archives are unlocatable
  -u Show a list of upgraded packages as well
  -b Build the source package after fetching it
  -V Show verbose version numbers
  -c=? Read this configuration file
  -o=? Set an arbitrary configuration option, eg -o dir::cache=/tmp
