    git clone https://github.com/skalenetwork/sgxwallet.git && git checkout stable
  4. Install required packages 
    apt-get install docker.io docker-compose build-essential
  5. Enable sgx 
    cd sgxwallet && sudo ./sgx_enable
  6. Install sgx driver 
    cd scripts; sudo ./sgx_linux_x64_driver_2.11.b6f5b4a.bin; cd ..
  7. Configure firewall between nodes and SGX server
  8. Upload sgx_data folder to sgxwallet/run_sgx/sgx_data on the new server
  9. Add -b option in command section of run_sgx/docker-compose.yml

Upgrade steps for the node server

  1. Turn off the node 
    skale node turn-off --yes --unsafe
  2. Backup the node 
    skale node backup .
    Save the data on another machine
  3. Upgrade packages 
    sudo apt update && sudo apt upgrade
sudo reboot
  4. Upgrade to Ubuntu 22.04 
    do-release-upgrade
reboot
  5. Turn off docker-lvmpy 
    systemctl stop docker-lvmpy && systemctl disable docker-lvmpy
  6. Make sure nftables is installed 
    sudo apt install nftables docker-compose-plugin
  7. Disable ufw ipv6 configuration 
    sed -i 's/IPV6=yes/IPV6=no/' /etc/default/ufw.
  8. Reload ufw 
    ufw reload
  9. Download new node-cli binary 
    curl -L https://github.com/skalenetwork/node-cli/releases/download/2.6.0/skale-2.6.0-Linux-x86_64 > /usr/local/bin/skale
  10. Verify node-cli binary hash sum 
    sha512sum /usr/local/bin/skale
    Expected checksum 
    15b2aade24223da4f84ec79bd820d57f852fd7a5d78f10652823629da28aab5db49a5815a2be0c894bb00b99324b00b7d9da2ab1518ddc11f304378af54b427c
  11. Make node-cli executable 
    chmod +x /usr/local/bin/skale
  12. Update the following parameters to the new values 
    CONTAINER_CONFIGS_STREAM=3.1.1
SGX_WALLET_URL=https://[NEW SGX WALLET SERVER IP]:1026
  13. Execute update 
    skale node update .env --yes
  14. Restart nftables and docker services
    Proceed with the execution in close collaboration with the core team, ensuring that the chains are fully stable beforehand.
    systemctl restart nftables && systemctl restart docker
