If it's not actually causing any issues, you can probably just ignore that one. It's a reasonably common error message with a dozen different causes, but rarely an issue in itself. I swear half the point of Linux is to expose issues that every OS has, just to give hyper autists something to spend their time on.
Sorry to hear it caused issues for you. You can btw validate any ISO you download and you probably should. Etcher will not help you on that, it just writes it on the USB. Also be sure to not use an old USB, I learned this the hard way myself before.
