After running the command sudo apt-get update

I got the following error:

W: GPG error: https://deb.nodesource.com/node_7.x xenial InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 1655A0AB68576280
W: The repository 'https://deb.nodesource.com/node_7.x xenial InRelease' is not signed.

E: Some index files failed to download. They have been ignored, or old ones used instead.

How can I fix this?

You're using a repository that has a security certificate problem. Until the repo maintainers fix that, the only way you'll be able to complete your update is to disable that repository. If it's only the two, that shouldn't be a big deal, and the issue should be temporary -- the repo maintainers should be notified every time their repo fails a security check.

You can get the Key from 'curl -s http://nsolid-deb.nodesource.com/gpgkey/NODESOURCE-NSOLID-GPG-SIGNING-KEY'

To fix that error you have to import that key for the repository you are using. To import the key for your repository, run the following command

curl -s http://nsolid-deb.nodesource.com/gpgkey/NODESOURCE-NSOLID-GPG-SIGNING-KEY | sudo apt-key add -
