I was trying to install beacon and got this error,
package--check-signature-content: Failed to verify signature: "seq-2.20.tar.sig"
Before installing, I ran
package-refresh-content which gave an error about the verification of a public key in
Failed to verify signature seq-2.20.tar.sig: No public key for <some id> created at 2019-09-21T12:54:43-0500 using RSA Command output: gpg: Signature made Sat 21 Sep 2019 12:54:43 PM CDT gpg: using RSA key <some key> gpg: Can't check signature: No public key
There was also this error in the
Contacting host: elpa.gnu.org:80 [2 times] Failed to download ‘gnu’ archive.

.emacs file's package archives variable looks like,
