I have this `phwmon.py`[1] which I use with fluxbox to have a couple of system monitors at hand. It depends on some python2 packages, so stopped working some time ago.
Any specific reason for preferring `phwmon.py` over a tool like `conky`?
I've just made it work, installing manually (# apt-get install packages.deb) this packages that I've downloaded from Debian OldStable official archives: python-psutil python-is-python2 (this is in fact in Testing) python-numpy python-pkg-resources python-cairo libffi6 python-gobject-2 python-gtk2 Therefore, my questions: How safe is this?
IMHO it's pretty OK because that is quite similar to having upgraded from an old system with the legacy packages installed to a new release where they are no longer part of.
Is it better to install them as I did, or adding the corresponding line in sources.list and pull them from there? Is there any difference?
There are differences: Whenever you install packages, you may not notice that they are only avaliable in old releases because the output of `apt-cache search` and similar tools will include old packages. Also, running a release with stable+oldstable in sources.list is less common than the other case: stable in sources.list and some oldstable packages leftover from upgrades. In case bugs are fixed in the oldstable package, you will get them automatically if you have them in sources.list.
My personal choice would be to install the packages without adding the oldstable repositories as to be reminded that they are obsolete and are likely to stop working in the future.
Be aware that libraries like `python-psutil` may not work with newer kernels. Here (on oldstable with a backported kernel 5.10) the script would not run due to excess fields reported by the kernel for disk statistics:

Btw. it looks as if `python-is-python2` is not needed for this to run? `phwmon.py` states `python2` explicitly.
