Installing signal-cli Signal messenger on a Raspberry Pi
23 August 2025 RaspberryPi
Whilst there are instructions on the GitHub site of how to install signal-cli we have to use an older version of the software because the current verion of Raspian doesn’t use Java Runtime Environment 21, only 17. It's probably possibly to install JRE 21 but I've opted for this route.
Make install directory
cd ~
mkdir signal-cli
