After 4dc5550, our GH Actions runners in Equinix (Ubuntu) can't detect the arch properly, throwing this error:
/root/actions-runner-3/_work/_actions/helm/kind-action/main/kind.sh: line 66: arch: unbound variable

When I run uname -m I get aarch64, which is not supported in the new case

root@keda-github-actions-runner-arm:~# uname -m
aarch64

The previous behaviour (dpkg --print-architecture) returned arm64
