I've just installed elementary OS Juno, but I'm getting into trouble when I try to get updates, both via AppCenter or terminal. It seems it cannot fetch updates since it cannot find Release file in the below repositories: enter image description here

Is there a way to fix this issue or change to correct repositiories?

  • I installed Juno just yesterday; had the same porblem. Would there be an oficial explanation, or solution to this issue? Replacing Juno with Bionic, will still keep the system updated? Nov 4, 2018 at 19:16

After checking every repository online, I fixed the issue by replacing juno with bionic in the below files: /etc/apt/sources.list /etc/apt/sources.list.d/appcenter.list /etc/apt/sources.list.d/elementary.list /etc/apt/sources.list.d/patches.list

Still, have no clue why the repository addresses were wrong.
