identify: error while loading shared libraries: libgvc.so.5: cannot open shared object file: No such file or directory

Question

On our Solano build image ubuntu14-chrome64 we install imagemagick in the pre_setup hook with the following command:

sudo apt-get update && sudo apt-get -y install imagemagick libmagickwand-dev graphviz libgraphviz-dev

But identify -version fails with

identify: error while loading shared libraries: libgvc.so.5: cannot open shared object file: No such file or directory

What is wrong with our imagemagick package installation there?

UPDATE 1:

$ which identify
/usr/local/bin/identify

$ ldd $(which identify) | grep not
    libgvc.so.5 => not found
    libgraph.so.4 => not found

UPDATE 2:

I did sudo rm /usr/local/bin/identify as @N0rbert advices but the error is left the same.

$ which identify
/usr/bin/identify

ldd $(which identify) | grep not outputs the same as in UPDATE 1

ls -lah /usr/bin/identify
/usr/bin/identify -> /etc/alternatives/identify

ls -lah /etc/alternatives/identify
/etc/alternatives/identify -> /usr/bin/identify.im6

Answer 1

You have self-compiled identify in /usr/local/bin/. Possibly from the time of 12.04 LTS release or similar.

You should remove it with

sudo rm /usr/local/bin/identify

and then you will be able to use normal one from the repository.
