Kouhei Sutou commented on ARROW-18045:
--------------------------------------
Thanks. It seems that your machine uses {{armhl}} Debian architecture.
We provide deb packages for {{arm64}} but not for {{armhl}}. If you use an
{{arm64}} based Ubuntu https://ubuntu.com/download/server/arm , you can use our
deb packages.
If you want to keep using {{armhl}}, you need to build Apache Arrow C++
manually before you install PyArrow. See
https://arrow.apache.org/docs/developers/cpp/building.html for details. You
need to specify at least {{-DARROW_PYTHON=ON}} CMake option.
