It seems my instance of python3 (on a Kubuntu virtual box) asked to install meep as part of some other package installation process. That installation failed, and now every time I try to install a packages I get a meep-related installation error. For instance, this just happened today.
pel@pel-VirtualBox:~/work$ sudo apt install pipenv

No amount of auto-removing purging or removing has had any effect. Update and upgrading have not worked. I'm at wits end. Does anyone have any suggestions short of ripping out python and reinstalling everything?
I had the same issue on my system. I have done something that is most likely not recommended. I did not have a choice except taking the risk. If you follow the procedure below, you are also taking a risk. However, the only assurance is that it worked for me.
The guilty package is python3-meep. It perhaps got upgraded without the package name being changed internally. This is where I confirmed the issue. A search revealed that the issue has been reported and fixed in Debian. It will perhaps take some time to make its way through to Ubuntu
So in the file
/var/lib/dpkg/info/python3-meep.postinstI replaced the occurrence ofpython-meepwithpython3-meep./var/lib/dpkg/info/python3-meep.prermI replaced two occurrences ofpython-meepwithpython3-meep.Then I could remove
python3-meepI would appreciate if someone points to a cleaner approach.
