## 🚒 Remediation on Ubuntu 24.04 LTS
- For connected systems just run
sudo apt update && sudo apt upgrade
- For air gapped systems: you can obtain the last sudo package from here: https://github.com/sudo-project/sudo/releases/download/v1.9.17p1/sudo_1.9.17-2_ubu2404_amd64.deb. Once the package has been transfered to the target system, just run:
sudo dpkg -i sudo_1.9.17-2_ubu2404_amd64.deb
