#203800 — Python issue?

Hi, I use phwmon [1] to have some system monitors on the taskbar.

Since last system update I have this message (and phwmon tries to
launch but fails):

$ phwmon.py
Traceback (most recent call last):
  File "Software/phwmon-master-b162e53dccc4adf8f11f49408d05fd85d9c6c909/phwmon.py",

Any hint/clue?

This seems to have already happened like a month ago [2], but the code
on GitLab hasn't changed in more than a year, so, the fix must have
come from some other way...

Thanks!

  _pslinux.py opens /proc/diskstats, and tries to parse the contents.

  It finds a line "    8 0 sda ..." which it doesn't understand.

  Perhaps you've upgraded your kernel, and different data has been
 stored in the file (which is a /proc file, and thus created by the
 kernel.)

  Opening a bug, then closing it with no reason why must be very
 frustrating for the maintainer.  Not to mention others who hit the
 same problem.

  Regardless it seems your problem is with the pslinux python
 library which I guess is the Debian package `python-psutil`:

Snipping entire report here.

Why do you call this a Python issue? Have you tried just running phwmon with
a different Python version to see if that solves the problem?

looks like maybe phwmon is not compatible with your current version of
python-psutil. Since the error does not occur here with Stretch I assume
you are running either Buster or Sid?
A possible workaround might be to copy the "psutil" folder of an older
compatible version into the directory where the phwmon executable sits.
However since there is some .so file included in python-psutil you would
probably have to compile first, and there is no gurantee that this will
work.

Regards

Michael
