### Lite Node Install Notes

Fresh install of Ubuntu 22

I decided to start with a lite node because they said in DC that there are too many validators right now.

So I followed this guide:

https://docs.celestia.org/nodes/light-node

I had two errors which I resolved like this:

install: cannot remove '/usr/local/bin/celestia': Permission denied
make: *** [Makefile:47: install] Error 1

1) I had to use `sudo make install`

The there was a go not found with sudo so...

2) I had to [manually add](https://stackoverflow.com/questions/71899341/go-command-not-found-error-when-using-sudo) go to sudo path as Go was not found with sudo.
