Maybe some useful replies will come out of this topic on the Ubuntu forums.Can you guys see if there's a PPA for Ubuntu Security Updates (Not Proposed) for Windowsfx/Linuxfx please? Maybe that might solve an issue w/ it.
I wonder if that indicates that all "security" updates will be selected by default and the user has no choice to "de-select" any of them? Kinda like Windows 10 updates
What do I do to get Security Updates on Windowsfx?You can, at your own peril, choose to not run security updates. And you will be pwned at some point because of that. What you can do on most Ubuntu based distros is select whether to auto install or not.
I don't know of any good reason to not want security updates. And by the way, security updates are incorporated into and released in the software that is affected by the security notice. Every security notice affects some piece of software and it's not always the kernel, most apply to browsers, spreadsheets, email clients, various and sundry drivers, and any piece of software you can think of. Security vulnerability is about being able to exploit some software unit on a computer - it's not always the internet.
Like in my Signature, I'm running Ubuntu Cinnamon.Going back to your original post. If the drop down menus don't work, and if running sudo apt update and sudo apt full-upgrade never produces and installs any updates, then you have two choices. One, reinstall linuxfx, or two get a different distro.
