# This script automatically downloads and installs the appropriate Netrinos client
# for the current system architecture. It should be run with superuser privileges.
#
# Usage:
#   sudo ./netrinos-remote-deb-installer.sh [version]
#
# or directly from the shell with:
#
# sudo true; wget -O- https://dist.netrinos.com/linux/netrinos-remote-deb-installer.sh | sudo bash -s [version]
#
# The script first detects the system architecture, then downloads the appropriate
# .deb package from the Netrinos distribution server. After downloading, it installs
# the package using dpkg.
#
# examples:
# netrinos-client-linux_daily_amd64.deb
# netrinos-client_linux1.1.0_amd64.deb

# Detect the system architecture
detected_arch=$(uname -m)

# Get the version from the command line argument, or use a default value
version=${1:-latest}

# Define the base URL of the .deb packages
base_url="https://dist.netrinos.com/linux"

# If version = latest, set folder = latest
