@john-53 I'm running Mint 20.2 Cinnamon

@john-53 - That error came from both update manager and cli sudo apt update. That happened after installing opera-stable_82.0.4227.33_amd64.deb. Purged Opera and installed opera-stable_79.0.4143.72_amd64.deb and everything is now working properly.

I'm getting the following error when running sudo apt update after installing opera-stable_82.0.4227.33_amd64.deb.

Err:11 https://deb.opera.com/opera-stable stable/non-free amd64 Packages
