I've found the patch applied to Eoan was the broken version where it used the bash'ism instead of the much more basic (and more portable) sh'ism of redirecting both STDOUT and STDERR.
I have confirmed this behaviour in Eoan (see bug #1850009) after doing an upgrade to this release.
I did a quick fix patch that is basically the same as #9 (I redirect only STDOUT however where as #9 redirects both STDOUT and STDERR).
