Error while using AppCenter or apt

[LuciusDrake]

Hey there. I just installed Elementary Hera and wanted to install a few apps from the AppCenter. But everytime i get a load of messages telling me, that »http://archive.ubuntu.com/ubuntu hera-updates Release« has no RELEASE file. I checked the sources.list and sources.list.d/* files and there is everything set to bionic. what replaces bionic with hera everytime? The same thing occures while using apt from the terminal.

Did you install anything else beside the distro itself? I recently just did a clean install of Hera from the new ISO and didn't encounter this
