The installation instructions list the following command for Debian and Ubuntu installation:
sudo apt install -y -V lsb-release wget
However, on a base Debian system configured to not install recommended packages, that results in wget producing the following error:
root@buster:~# wget https://apache.bintray.com/arrow/$(lsb_release --id --short | tr 'A-Z' 'a-z')/apache-arrow-archive-keyring-latest-$(lsb_release --codename --short).deb

It is necessary to have the ca-certificates package installed for wget to be able to verify the issuer and server certificate. The wget package recommends, but does not depend on, ca-certificates, so the documentation should include it in the supplied command line.
The command should be updated to:
sudo apt install -y -V lsb-release wget ca-certificates
