It's weird because I've installed Mint on other PCs and Macs and have never seen this problem before (admittedly probably slightly older versions of Mint), which keeps recurring on my machine.
OK. Unfortunately, I don't use Mint, so I was hoping it would contain more information. I would have to go the same route as you and start searching the web to find answers.
If you copy paste the error message into a search engine, you'll probably get some guidance. Most likely it's something others have experienced.
