That’s not how I set out my list of instructions. You can’t just jump from root to user and back again. You’ll have a load of issues with file permissions and file ownership when you eventually get TVH built and installed.
I strongly suggest that you start again with a fresh install of Ubuntu 22.04 and use these posts as a guide to what you need to install to finally get TVH built/compiled as a package ready for installation.
If you already have TVH installed and configured from precompiled packages and are happy enough with that fine, but as it stands the build/compilation process for you has gone off script and will probably need some work and a good knowledge of Linux to put right. The decision is entirely up to you.
