Keys Conflict

[tg30 <tg30@pm.me>]

After successfully installing google-chrome-stable I encountered the follow problem:

sudo apt-get update

E: Conflicting values set for option Signed-By regarding source http://dl.google.com/linux/chrome/deb/ stable: /var/lib/extrepo/keys/google_chrome.asc !=

E: The list of sources could not be read.

The browser works fine but I can no longer update the mint distribution.

Any suggestions on how to fix this?
