ValueError: unknown action "extend"?

[yxiang92128]

The installation of "stratis-cli" seems to have completed successfully. But when I ran it, it generates the following error:

stratis pool create
Traceback (most recent call last):
  File "/usr/bin/../bin/stratis", line 4, in <module>

any idea how to fix it?

It looks like using Python 3.8 should fix the problem, although stratis-cli officially requires 3.9, so that's the best choice. But Python 3.6 is too old.

[mulkieran]

Thanks for catching that. We'll add a python_requires key in setup.cfg. We don't release on PyPI, so we never came across this before, Fedora packaging enforces the Python requirement.

I upgraded to python3.11 but now it is reporting a different issue when running stratis CLI:

stratis

[mulkieran]

That's a deal more tricky. What you're encountering here is a problem with a dependncy dbus-python. It's a wrapper around a C library, and something has clearly gone wrong with how it wraps the library. So, you'll have to give up some system information, like how the dbus library was installed. We can investigate if this is happening on a Fedora distribution, but less so on others. If you want to pursue it further, the right thing is to open a Python interpreter and enter:

> import dbus.types as types

and see what happens. Probably the same error and that makes it a packaging bug or a dbus-python bug or something further down in the dependency tree.
