Ubuntu – Cannot launch ImageMagick

Did you read this:

I'm generally not a big friend of ppa's, but there is actually no other way to receive bugfixes for Kubuntu than using the backports-ppa. Well 14.04 had KDE4 and it's an LTS. Any STS get's only 9 month support, so anyone is taking part in development to a stable release. I have a LTS+ a STS on the PC (that way it's not too frustrating. After Trusty Kubuntu enters a new Aera with Plasma-KF5 & Applications-KF5. Some edges and corners have to be expected in my mind :-) The good thing about the backports-ppa is it will not hinder a system update lateron, as it doesn't contain newer versions than in the next release.

edit2: Upon the answer that this didn't change a lot, I suggest U take a look a the installed Java-Version

$ java -version

If it's OpenJDK-7, just install OpenJDK-8.

Background: Could as well be this bug (see also bug-duplicates there):

edit3: Just forget my last comment, bugfix was published to the masses yesterday.
