What have you tried:Have tried every suggestion on co-pilot github
What is the error: error running pypy3 rtupdate hook public_modules.rtupdate
dpkg: error processing package pypy3 (–configure)
What device is this on: debian vbox
Have you installed some python package and now it wont work?
It is better to tell us what you are trying to achieve than just posting an error message out of context. just asking that error message with an AI like copilot will also have little success for the same reason
I believe they’re trying to install a package that depends on pypy3 but seems to be throwing this error when pypy3 is trying to install and dpkg, i am also having this issue with the same vbox configuration, unsure on what is causing it though if anyone is able to help out that’d be awesome 
I have a similar issue. kali 24.4. I’m trying to get routersploit running. Routersploit is installed but requires pypy3-venv, which needs pypy3. Installing thru pipx doesn’t work either and kali docs prefers using apt if there is a package. apt has pypy3 (7.3.19+dfsg-2). when using apt I get this error;

once you have the pypy3 virtual environment set up, try installing pypy3 again.
I believe pypy3 must be installed first but pypy3-venv. I have tried countless tutorials, install, reinstall, purge etc. results from your suggestion below.

Pypy3 and pypy-venv will install, but won’t configure and hence routersploit encounters module errors.
I think its because Kali is using Python version 3.13.2 and according to the pypy website;
its built against Python 3.11
Thanks, thats the best answer so far.
I decided to not use routersploit as it seems the last update was 2022.
As i am no longer interested, i will consider this thread abandoned.

Is there a solution to this? I am experiencing the same error and I need to install a module needed for a cve. thanks.
You could install an earlier version of Python that pypy3 would be happy with, the easiest way is to use pyenv which is a container for python;
If you want to do this more globally, have a read here;
