RoonBridge on RaspberryPi2

I tried to install RoonBridge on RaspberryPi2, but I was not able to proceed properly.

RaspberryPi’s OS is Raspberry pi OS (Legacy, 32-bit) Lite.

I downloaded the easy installer linuxarmv7hf and ran the installer.
However, an error like this appears and I am unable to continue the installation.

Is there anyone who knows the solution? I would appreciate it if you could let me know.
Is there a place to change settings such as Config?
