Persuant to my claim the py3.10 is busted, here is a sample. This

trying to make
pronterface, inside a venv: When the package manager version will
only run
the gui-less "pronsole"
but nothing else from that all python kit runs as it should or at
all.
From the package-managers install in
/usr/share/doc/printrun-common/ I
copied requirements.txt
into the venv, and ran this command line:
gene@rock64:~/venv$ pip3 install -r requirements.txt
You are almost certainly *not* in a venv here. First, your prompt
doesn't show the name of the venv,
I've created that several times, as octoprint won''t run without it
either.
I found a way to autostart it on reboots and octoprint seems happy
with it
I agree with Peter: it doesn't look as if you are invoking the pip3
in the venv. Just making the venv-directory the current directory
doesn't activate it.
As a diagnostic, ask the OS which pip3 is actually used:
$ type -a pip3
Does that show the pip3 installed in the venv? Or the system-wide
one? If it's not the pip3 in the venv, well, then that's the problem
(or at least part of the problem). Solution: first check whether the
venv really contains 'pip3' (as opposed to eg. just 'pip'): list the
contents of the bin subdirectory of the venv. If not, use 'pip' or
whatever instead. Then to make sure you use the one in the venv,
either activate the venv or explicitly specify the path when invoking
pip/pip3 (and likewise for python/python3).
So either (assuming you're using bash):
$ source {path_to_venv}/bin/pip3 # activate the venv
I think this first line should probably be:
$ source {path_to_venv}/bin/activate # activate the venv
i.e. with `activate` rather than `pip3`?
$ type -a pip3 # check whether now the correct pip3 is used
$ pip3 install -r requirements.txt # finally invoke pip3
or:
$ {path_to_venv}/bin/pip3 install -r requirements.txt
That got me to showstopper #2: (lengthy warniing)

There is help there, but to me its engrish. Next fix?
Activating the venv is easier if you're going to use multiple
commands in the venv. Note that activating the venv only has effect
on the current shell; other shells are unaffected, and when you close
the current shell the venv is not activated anymore.
Explicitly using the path is easier for one-off calls, or in things
like crontab.
Thank you Mark Bourne, this looks like actual progress in what has
turned into a cast iron bitch.
I'll not touch that shell till the next advice is tendered. However
"echo $PKG_CONFIG_PATH" is
null in this venv.
Cheers, Gene Heskett.
