Chrome install failed due to missing public key used for signing
Chrome releases:

```
\#6 2.433 W: GPG error: https://dl.google.com/linux/chrome/deb stable InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY E88979FB9B30ACF2
\#6 2.433 E: The repository 'https://dl.google.com/linux/chrome/deb stable InRelease' is not signed.
