Mageia is really easy to install and use.

Thanks for all the helpful suggestions. After about five attempts, I was finally able to install Ubuntu 16.04 LTS successfully. Each time I ran the DVD I made a little more progress. But the penultimate attempt really scared me. I couldn't boot either Ubuntu or Windows 10 in my targeted dual-boot system. But at that point I figured I had nothing more to lose from another attempt. To my amazement, the next pass went without a hitch. However, I found the latest LTS version of Ubuntu rather disappointing. For example, it had a really ancient version of Eclipse in the software installer. Looks like they keep updating the core OS but never update anything else.

A couple idea(s), from web-search of: ubuntu version of Eclipse

That's the price of stability.

To download and install the latest version of Eclipse: https://eclipse.org/downloads/index-...p?osType=linux

The above is exactly correct.
You can bypass the repo and related security, but you do adopt some risk in the process.

Understand, if you want to ride the cutting edge, you must expect to bleed a bit.
I like to run VSIDO and SPARKY LINUX. I love that I can get the very latest packages for them, but at times a package update will disable some function I need until the supporting packages catch up. LTS versions are valued for stability, and for stability you sacrifice being on the cutting edge.

If it is some comfort, both RHEL and UBUNTU backport major and security fixes into their LTS packages. Your feature set may be old, but they are generally not significantly less secure than the latest release.
