What's the recommended way to run 0.4.7 on armhf?
The package repository [deb.torproject.org] does not offer 32-bit ARM architecture (armhf) images (yet).
https://support.torproject.org/apt/tor-deb-repo/
Debian has 0.4.7 in bullseye-backports.
But Raspbian doesn't have bullseye-backports: http://raspbian.raspberrypi.org/raspbian/dists/
Right. One thing we recommended when talking to relay operators during earlier EOL upgrade periods is adding the debian -backports repository to the Raspberry Pi. It worked well according to the feedback we got. We linked to

for general steps (you need to adapt them for bullseye, though).
Hope this helps, Georg
