Error during cherry picking

[mkaraev]

I ran cherry_picker 27ed64575d34f04029ba1d353810f3db4f4f045b 3.13 from this PR python/cpython#133907 (comment)
and got conflicting files. Fixed conflicts and tried to run cherry_picker --continue and got this strange error:

Further attempts to run cherry_picker --status or cherry_picker --abort failed with error:

Run state cherry-picker.state=CONTINUATION_STARTED in Git config is not known.
Perhaps it has been set by a newer version of cherry-picker. Try upgrading.
Valid states are: BACKPORT_PAUSED, UNSET. If this looks suspicious, raise an issue at https://github.com/python/cherry-picker/issues/new.
As the last resort you can reset the runtime state stored in Git config using the following command: `git config --local --remove-section cherry-picker`

I'm using cherry_picker version 2.5.0

Please, run git fetch origin 3.13

Will it solve your issue?

Will it solve your issue?

Nope :)
I'm still getting the same error.

@sobolevn ohh, I got what you meant. I needed local copy of 3.13. That solved my problem. Thank you!

I think it's a duplicate.
