When I setup Elasticsearch on Ubuntu, I made a mistake when putting 7.11.2 to: echo "deb [https://artifacts.elastic.co/packages/7.11.2/apt](https://artifacts.elastic.co/packages/7.11.2/apt) stable main" | sudo tee -a /etc/apt/sources.list.d/elastic-7.11.2.list so now, when running sudo apt-get update, there is a error: Err:6 [https://artifacts.elastic.co/packages/7.11.2/apt](https://artifacts.elastic.co/packages/7.11.2/apt) stable Release 404 Not Found [IP: xxxx] How do I modify it in /etc/apt/sources.list? Any help welcome ! ---

I would just `rm /etc/apt/sources.list.d/elastic-7.11.2.list` and then readd it. ---
