Just finished taking this for a spin, both on armhf (to ensure it now
works) and amd64 (to smoke test for no regressions).
Here is an up-to-date amd64 using 1.4~rc1-1build2:
$ cat << EOF >> test.py
> #!/usr/bin/env python3
>
> import pygraphviz
>
> graph = pygraphviz.AGraph()
> graph.add_node('foo')
> graph.add_node('bar')
> graph.add_edge('foo', 'bar')
> print('success!')
> EOF
$ chmod a+x test.py
$ ./test.py
success!
After installing 1.4~rc1-1build2.1 the results are unchanged-- it continues
working:
$ sudo apt install python3-pygraphviz/bionic-proposed
<snip>
Setting up python3-pygraphviz (1.4~rc1-1build2.1) ...
$ ./test.py
success!
Now, here is an up-to-date armhf using 1.4~rc1-1build2:
$ cat << EOF >> test.py
> #!/usr/bin/env python3
>
> import pygraphviz
>
> graph = pygraphviz.AGraph()
> graph.add_node('foo')
> graph.add_node('bar')
> graph.add_edge('foo', 'bar')
> print('success!')
> EOF
$ chmod a+x test.py
$ ./test.py
Traceback (most recent call last):
File "/usr/lib/python3/dist-packages/pygraphviz/agraph.py", line 1561, in
__new__
nh = gv.agnode(graph.handle, n.encode(graph.encoding), _Action.find)
KeyError: 'agnode: no key'
During handling of the above exception, another exception occurred:
Traceback (most recent call last):
File "./test.py", line 8, in <module>
graph.add_edge('foo', 'bar')
File "/usr/lib/python3/dist-packages/pygraphviz/agraph.py", line 478, in

e = Edge(self, eh=eh)
File "/usr/lib/python3/dist-packages/pygraphviz/agraph.py", line 1625, in

s = Node(graph, nh=source)
File "/usr/lib/python3/dist-packages/pygraphviz/agraph.py", line 1563, in
__new__
raise KeyError("Node %s not in graph." % n)
KeyError: 'Node None not in graph.'
Broken, as mentioned in the bug report. Now with 1.4~rc1-1build2.1:
$ sudo apt install python3-pygraphviz/bionic-proposed
<snip>
Setting up python3-pygraphviz (1.4~rc1-1build2.1) ...
$ ./test.py
success!
Fixed! Marking verification done.
