error running python rtupdate hook hplip-data
dpkg: error processing package python3 (--configure):
 installed python3 package post-installation script subprocess returned error exit status 4
----------

On every update the python3 package calls a script in the /usr/share/python3/runtime.d/ for each Python library to recompile the Python files with the new Python3 version.

When it comes to the script for the Python files of the hplip-data packages it complains about missing Python files. hese files are actually part of hplip-data, according to the output of "dpkg -L hplip-data", and the script /usr/share/python3/runtime.d/hplip-data.rtupdate also belongs to the hplip-data package, so if the script is present these Python files must be present, too.

The problem with HPLIP is most probably that users install HPLIP directly from HP's site (upstream) to support the newest HP printers. This installation overwrites the Python files of hplip-data. Later on they remove the upstream HPLIP installation which removes all these Python files, but the Debian package hplip-data is still registered as installed and as the script /usr/share/python3/runtime.d/hplip-data.rtupdate comes from the Debian package and not from HP, it is still there after the upstream removal of the HPLIP package. Weeks or months later we have an update of the python3 package and get this error.

Possible remedies:

1. Dirty workaround: Let /usr/share/python3/runtime.d/hplip-data.rtupdate ignore errors, always "exit 0".

2. Turn HPLIP into a snap. This way the packaged HPLIP is sandboxed and an upstream installation does not overwrite it. If HP adopts snapping, their HPLIP replaces the HPLIP snapped by us and independent whether the HPLIP snap is done by us or by HP, updates come independently of our release cycles and so one can easily get the newest HPLIP on an already released Ubuntu version, without needing to install from upstream source.

3. Do away with HPLIP for modern printers. Modern printers (at least network ones) work driverless, both for printing and for scanning, using current CUPS, cups-filters, and SANE (version 1.0.29, with "escl" backend).

Quick workaround:

sudo apt install --reinstall hplip-data
