Unable to check for updates - 2.3-RC

[Marc05]

When going to System / Updates, I get the following error:

ERROR: Error trying to get packages list. Aborting…
pkg: No trusted public keys found pkg: No trusted public keys found pkg: No trusted public keys found pkg: No trusted public keys found pkg: Repository pfSense-core cannot be opened. 'pkg update' required pkg: Repository pfSense cannot be opened. 'pkg update' required

There weren't any issue updating throughout the beta timeline.
