Q:

Can't install software, dpkg returns error while processing python3-distupgrade

Installation of software results in the following error:
Processing triggers for desktop-file-utils ...
Setting up python3-distupgrade (1:0.190.2) ...
Could not import runpy module
Traceback (most recent call last):
  File "/usr/bin/py3compile", line 289, in <module>

Original exception was:

E: Sub-process /usr/bin/dpkg returned an error code (1)

'sudo dpkg --configure -a didn't solve the problem. How can I fix this?

A:

Removing python solved the problem. Reïnstalling python gave the same error. While I do not use python3 I do not mind. But it seems a bug to me.
