The programs that I want to run (by converting to Python 3) are utility programs for my printer, they install with a handy 'app' in my toolbar. Having them in a VM wouldn't really do much good! :-) > Have you checked an upgraded Ubuntu to failure to run your software > using Python 2?

The issue is that the programs need modules which come from a PPA to support Python GTK, these conflict with ongoing updates to Python. The PPA works OK in Ubuntu 20.04 but prevents some updates in 20.10. I expect it will get worse as time goes on. > >The specific error I'm getting is as follows:- > > File "/usr/libexec/okimfputl.new/guicom.py", line 66, in <module> import > > pyscand > > ImportError: /usr/libexec/okimfpdrv/pyscand.so: undefined symbol: > > _Py_ZeroStruct > > > Guessing from the library name, have you looked on the OKI.com site for > current software?

I have tried asking them for a Python 3 version, maybe I should try again. -- Chris Green · -- https://mail.python.org/mailman/listinfo/python-list
