<div>Hi Andrew</div>
<div><br>
</div>
<div>I checked the file you shared ; it is exactly the same
symptoms as this, for Ubuntu 18.04:</div>
<div><a

<div><br>
</div>
<div>In short, you seem to have at some point installed
HPLIP HP's own install script, and HP's installer is very
broken. Quoting from the linked article:</div>
<div style="margin-left:40px"><br>
</div>
<div style="margin-left:40px">The problem is HPLIP
installer. It incorrectly uni'm running the commands
now.nstalls Ubuntu-packaged version by deleting files,
which are maintained by package manager.</div>
<div><br>
</div>
<div>The answer advocated is listed here:</div>

<div>To cut
the steps to
what looks
like what you
need:</div>
<div><br>
</div>
<div>* get the
installer/uninstaller script for HP's custom install</div>
<div>*
uninstall
HPLIP custom</div>
<div>*
reinstall
python3</div>
<div>* fix
installations</div>
<div>* install
distro's own
hplip support</div>
<div><br>
</div>
<div>Commands:<br>
</div>
<div><br>
</div>
<div
style="margin-left:40px">
<pre><code>wget <a href="https://kent.dl.sourceforge.net/project/hplip/hplip/3.18.12/hplip-3.18.12.run" moz-do-not-send="true">https://kent.dl.sourceforge.net/project/hplip/hplip/3.18.12/hplip-3.18.12.run</a> &&

<div>WARNING -
some of the
above commands
are
assumptions -
I have not
tested these,
my system is
not in this
state so I
cannot confirm
their
correctness.</div>
<div><br>
</div>
<div>After the
`sudo rm ...`
step, it may
in fact be
necessary to
remove python3
and then
reinstall it
*however* that
may have for
effect to
remove other
key packages
than just
python3 (which
is why I do
not list a
command for
it)</div>
<div><br>
</div>
<div>If the
apt-get -f
install
command fails,
try running
`sudo apt-get
install
--reinstall
python3` to
see if this
helps, then
run the
commands from
-f install
again.</div>
