Linux package upgrade detection fails on Ubuntu 24 LTS but locally there are security updates available for installation
The issue here is that the /etc/apt/sources.list file in Ubuntu 24 is deprecated. There's a note inside the file stating:
*************************************************************************
# Ubuntu sources have moved to the /etc/apt/sources.list.d/ubuntu.sources
# file, which uses the deb822 format. Use deb822-formatted .sources files
# to manage package sources in the /etc/apt/sources.list.d/ directory.
# See the sources.list(5) manual page for details.
*************************************************************************
The ubuntu.sources file is in a different format now. Example:
*************************************************************************
Types: deb
URIs: http://archive.ubuntu.com/ubuntu/
Suites: noble noble-updates noble-backports
Components: main universe restricted multiverse
Signed-By: /usr/share/keyrings/ubuntu-archive-keyring.gpg## Ubuntu security updates. Aside from URIs and Suites,
Types: deb
URIs: http://security.ubuntu.com/ubuntu/
Suites: noble-security
Components: main universe restricted multiverse
Signed-By: /usr/share/keyrings/ubuntu-archive-keyring.gpg
*************************************************************************
This will be addressed on a future release of the agent since this change was made by Ubuntu. As a workaround, you could create an online shell script that triggers the commands to upgrade the packages on the device
