File Mapping is what is run at the start of the image load. It looks like we have Java 17 and VSCode elements here here which could be adding to custom files for S3.

Here is the text

We need to move to Noble on Ubuntu. Also, I would like to try using Kali as it is popular in cybersecurity and compatible with apt.

Ubuntu 24.04 LTS is the 2024-April release; it's the noble numbat release. Ubuntu's prior LTS was Ubuntu 22.04 LTS released in 2022-April; thus has two years less of supported life left. Its codename is jammy jellyfish.
