I am trying to update Truffle on Ubuntu 18.04. I currently have version 5.1.33 installed on my system.

u/lc2530hz:~$ truffle version You can improve web3's peformance when running Node.js versions older than 10.5.0 by installing the (deprecated) scrypt package in your project Truffle v5.1.33 (core: 5.1.33) Solidity v0.5.16 (solc-js) Node v8.10.0 Web3.js v1.2.1

I am getting following error message:
