# Mandatory step for Ubuntu versions 22.04 and 24.04 is to install libssl 1.1, not available in Ubuntu repo since 22.04
# wget http://security.ubuntu.com/ubuntu/pool/main/o/openssl/libssl1.1_1.1.0g-2ubuntu4_amd64.deb
# sudo dpkg -i libssl1.1_1.1.0g-2ubuntu4_amd64.deb
 
# Then download the client and install it - possible troubleshooting needed

# Check .bashrc
if [[ $(cat ~/.bashrc | grep -c "export DOTNET_SYSTEM_GLOBALIZATION_INVARIANT=1") -ne 1 ]]; then
	echo "export DOTNET_SYSTEM_GLOBALIZATION_INVARIANT=1 line is missing in your .bashrc file, add it"
	exit 1
fi
 
# Check /etc/systemd/system/awsvpnclient.service
if [ -f /etc/systemd/system/awsvpnclient.service ]; then
	if [[ $(cat /etc/systemd/system/awsvpnclient.service | grep -c DOTNET_SYSTEM_GLOBALIZATION_INVARIANT=1) -ne 1 ]]; then
        echo "Environment=DOTNET_SYSTEM_GLOBALIZATION_INVARIANT=1 line is missing in"
	echo "/etc/systemd/system/awsvpnclient.service file, please add it after User=root"
        exit 1
        fi
fi
