I am a new user and I am having trouble working around this issue. When I sudo-apt update, I get the error:

  • There may (probably) be other errors, but those font color things should not be in there. Did you edit your sources list by cutting and pasting from a web page? You also appear to be using Pop OS, which is off topic here. – Organic Marble May 01 '21 at 14:12
  • Follow the [last two commands in this answer](https://askubuntu.com/a/508337/167115) (making sure to substitute C8CAB6595FDFF622 for the key) to fix the no pubkey error and then update your question if you still have errors. Thanks. – mchid May 01 '21 at 19:32
  • i apologize, i am relatively new and just thought bc its Ubuntu based. the only thing i have done since install is install snap store. – raptorchip2019 May 01 '21 at 19:38
