• ImageMagick package installed is ImageMagick-6.7 or older:

  # rpm -qa | grep -i magick
  ImageMagick-6.7.8.9-18.el7.x86_64

• ImageMagick does not update to a newer version:

  # yum update ImageMagick
  Loaded plugins: fastestmirror, langpacks
  Loading mirror speeds from cached hostfile
  No packages marked for update

• CentOS-Base repo contains the following baseurl:

  # cat /etc/yum.repos.d/CentOS-Base.repo
  [base]
  …
  baseurl=http://olcentgbl.trafficmanager.net/centos/$releasever/os/$basearch/

Cause

Incorrectly configured repository prevents ImageMagick from being updated to a newer version, which provides libMagickCore-6.Q16.so.6()(64bit).

Resolution

1. Connect to the server via SSH;
2. Open this file with a text editor: /etc/yum.repos.d/CentOS-Base.repo:
3. Comment out baseurl or remove it, and add the following mirrorlist under [base]:

   [base]
    name=CentOS-$releasever - Base
    mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os&infra=$infra
    #baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/rch/ 

4. Update ImageMagick:

   # yum update ImageMagick

5. Update Plesk:

   # plesk installer update
