• Well, it's a problem with MS not supporting an LTS (long term support) version. I'd expect that MS moves to support the LTS or active branches. This seems more like MS hasn't updated some of their stuff to patch for Ubuntu.

    I appreciate that  now that they're supporting 4 OSes, there are likely some holes in the way they patch. They have OS specific patches, so this is odd. Unless Ubuntu made a change from 16.x to 18.x that isn't easily resolved and they are avoiding the IF logic on code to look for versions.
