Fresh install of Elementary OS. Did a "sudo apt-get update" getting the following error message:
Err:## http://packages.elementary.io/appcenter hera Release 404 Not Found
Also, in the App Centre, NONE of the "Elementary Apps" are available (except for the presinstalled ones). Only able to download the Non-Curated Apps.
(fixed spelling mistake on recent edit)
Further to the above:
E: The repository 'http://packages.elementary.io/appcenter hera Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
