I need to install Imagemagick on a cloud server:
apt-get install imagemagickReading package lists... Done
Building dependency tree
Reading state information... Done
Package imagemagick is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'imagemagick' has no installation candidate
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 12.04.1 LTS
What repository do I need to add?
