I have Linux Mint on my Dell laptop and have had it for 1 1/2 years now. Doing sudo apt update got this:
GPG error: http://dl.google.com/linux/earth/deb stable InRelease: The following signatures couldn
't be verified because the public key is not available: NO_PUBKEY 4EB27DB2A3B88B8B
E: The repository ‘http://dl.google.com/linux/earth/deb stable InRelease’ is not signed.

does not have a Release file.

So went to Software Source Repositories and unchecked opensuse
because the page is no longer available. Now when I do sudo apt update I get no error but I need to add a repository to replace the Opensuse one:
http://download.opensuse.org/repositories/home:/strycore/xubantu_16.04//
What Repository do I add to replace opensuse and where do I find it.
Thanks
