Dear Maintainer,

I was trying to do a routine backup with borgbackup2, using a simple script. It
failed immediately, with the error below. (I'm not worried about y'all seeing
my directory structure.) Usually it would prompt me for a password, but it
didn't get to that point.

I also have borgbackup-is-borgbackup2 installed.

It doesn't look like borgbackup2 has been updated since the last time I
successfully used it, about two weeks ago.

  Hello:

  I think this bug is related to the python3-borgstore version.

https://github.com/borgbackup/borgstore/blob/master/docs/
changes.rst#version-050-2026-05-28[1]

  I think currently packaged borgbackup2 version (2.0.0b20) requires a lowe python3-
borgstore version (lower than 0.5.0). It looks only latest borgbackup from git support
borgstore versions greater than 0.5.0.

  Regards,
