This is my Ubuntu 22.04 on VirtualBox:
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 22.04.1 LTS
Release: 22.04
Codename: jammy
When I do sudo apt update, the following error happened.
E: The repository 'http://security.ubuntu.com/ubuntu impish-security Release' does not have a Release file.
What is the reason please?
====update Sep 23 2022====
This worked for me:
mkdir ~/.apt-backup
sudo mv /etc/apt/sources.list.d/impish-security.list* ~/.apt-backup
