Dot doesn't support any format in a newly installed Graphviz

Question

I have installed Graphviz on Fedora using the recommended procedure described at GraphViz official site. However, I'm not able to convert a basic hello.dot file using dot command.

My hello.dot file is:

graph hello {
    Node1 [label="Hello, World!"]
}

The error is:

$ dot hello.dot -Tpng -o hello.png
Format: "png" not recognized. Use one of:
$

It looks like there is a bug in the official install. After running the command 'dot -c', the problem has been solved.

Could you suggest how to do that if I do not have sudo command. (on server at Heroku)? – Shirleeshirleen

The problem is linked to a bug in the install process. Hence, in case dot has been installed in privileged mode, you need to have hand on the same privileged mode to fix the problem. – Decode

Surprisingly, even new releases (2.44) still as this issue... – Hamachi

The graphviz-gd package is also required. See also #35688820 – Pock
