Hello Ihor,
Is there an environment variable that could be used to determine is the
tests are being run on sourcehut? This would let us cut out that test on
sourcehut, while still keeping it elsewhere.

An earlier test is creating that *Org Babel Error Output* buffer. That
is killed on the first test, before the test is actually run. But
GET-BUFFER behaves in an undocumented way: it returns a non-nil value,
#<killed buffer>. To remedy that, I have wrapped the calls in
BUFFER-LIVE-P.
See the attached patch.

Subject: [PATCH] test-ob-octave.el: wrap get-buffer in buffer-live-p
* testing/lisp/test-ob-octave.el (ob-octave/graphics-file):
(ob-octave/graphics-file-session):
(ob-octave/graphics-file-space): Wrap GET-BUFFER in BUFFER-LIVE-P.
This ensures that a killed buffer does not cause an incorrect failure
of a test.
