Update Ghostscript on Ubuntu 14.04

First of all, I am well aware of this question: What's the easiest way to upgrade Ghostscript?.

Unfortunately none of the answers worked. I can find deb files from this list. There, I am surprised to see that the last version of Ghostscript for Ubuntu 14.04 is version 9.10. When I download version 9.15 for Ubuntu 15.04, and I run it (as root), I get the error:

Error: dependency is not satisfiable libgs9

I checked (apt-get install libgs9) and I have the latest libgs9 installed. Also, this site seems to confirm that last is version 9.10 for 14.04.

Does this mean it is not possible to upgrade Ghostscript?

Solution 1:

What do you want to do is not possible. At least not without making your system broken.

You can't install the Vivid version of ghostscript in Trusty. The package has some dependencies and one of them is libgs9 (= 9.15+dfsg-0ubuntu2.1). The version for libgs9 in Trusty is libgs9 (9.10~dfsg-0ubuntu10.4). Therefore, forget it. :)

Repair your system via

sudo apt-get install -f

In the meantime you could try this PPA

sudo apt-add-repository ppa:anton+/photo-video-apps
sudo apt-get update
sudo apt-get install --reinstall ghostscript
