Building the IVPN CLI Client for Linux on a Raspberry Pi

1. Install packages for compiling, building, and connecting:

   $ sudo apt install ruby ruby-dev ruby-full rpm curl git openvpn libiw-dev
   

2. Install FPM:

   $ sudo gem install --no-document fpm
   Fetching ...
   ...
   Successfully installed fpm-1.15.1
   

3. Determine the ARM architecture for your Raspberry Pi device:

   $ uname -m
   

   32-bit systems will be identfied with armv6l or armv7l and 64-bit systems with aarch64.

   Install the most recent version of Go via https://golang.org/dl/ for your device’s architecture:

   $ wget https://go.dev/dl/go1.20.5.linux-arm64.tar.gz
   $ sudo tar -C /usr/local -xzf go1.20.5.linux-arm64.tar.gz
   $ rm -i go1.20.5.linux-arm64.tar.gz
   

   Note: The IVPN Client requires Go version 1.18 or higher and the Raspberry Pi OS repositories include an older version of the golang package:
   
   $ apt-cache policy golang golang: Installed: (none) Candidate: 2:1.15~1

4. Add Go to the $PATH and define the $GOPATH variable by adding two lines to the bottom of ~/.profile, then source the file:

   $ echo -e "\n\nPATH=$PATH:/usr/local/go/bin\nGOPATH=$HOME/go" >> ~/.profile
   $ source ~/.profile
   

   Verify the changes and add the $GOPATH folder:

   $ which go
   /usr/local/go/bin/go
   $ mkdir -v $GOPATH
   mkdir: created directory '/home/pi/go'
   

5. Follow the build instructions for the Linux base package (daemon + CLI) from the IVPN App’s GitHub page:

   $ git clone https://github.com/ivpn/desktop-app.git
   $ cd desktop-app/cli/References/Linux/
   $ CL="https://raw.githubusercontent.com/ivpn/desktop-app/master/CHANGELOG.md"
   $ VER=$(curl -s $CL | grep "## Version" | head -n 1 | awk '{ print $3 }')
   $ echo $VER
   $ ./build.sh -v $VER
   ...
   ---------------------------
   DEB package...
   Created package {:path=>"ivpn_3.10.23_arm64.deb"}
   ---------------------------
   ...
   Copying compiled packages to '/home/pi/desktop-app/cli/References/Linux/_out_bin'...
   

6. Install the new package:

   $ sudo apt install ./_out_bin/ivpn_3.10.23_arm64.deb
