ImageMagick still exists after apt remove?

Solution 1:

The imagemagick package is a dummy package. From apt show imagemagick

 .
 This package include links to channel depth specific binaries and manual
 pages.

 This is a dummy package.  You can safely purge or remove it.

The "channel depth specific binaries and manual pages" are provided by the package's dependency - you can check what that is using apt depends - for example:

$ apt depends imagemagick
imagemagick
  Depends: imagemagick-6.q16 (>= 8:6.9.2.10+dfsg-2~)
    imagemagick-6.q16:i386

(the q16 here refers to the the channel depth). If you installed imagemagick via apt (or apt-get) this will be the package that you need to remove.

If you installed the software by building it from source code, then please refer to
