$ sudo apt update...Ign:6 https://packagecloud.io/AtomEditor/atom/any any InRelease Err:8 https://packagecloud.io/AtomEditor/atom/any any Release 404 Not Found [IP: 52.8.40.176 443]E: The repository 'https://packagecloud.io/AtomEditor/atom/any any Release' no longer has a Release file.N: Updating from such a repository can't be done securely, and is therefore disabled by default.N: See apt-secure(8) manpage for repository creation and user configuration details.How do I resolve this update issue?
The AtomEditor was previously installed in this system but was removed after it was discontinued. Seems that the removal is incomplete despite not appearing in Software & Updates - Other Software.
There is an associated question but I can't use it's answer because as I have shown above I don't have the ppa path for Atom that I can use with the ppa-purge command.
Can you provide me with the exact command(s) I need to give to resolve this issue? I have tried these commands but non of them works:
