Let me start by saying that I am strictly a Long Term Support (LTS) person. I have been using Ubuntu since 10.04. Over the years I have dabbled into using interim releases, but, to tell you the truth, I don’t have that much free time to be forever mucking about with my OS.
Enter Oracle VirtualBox. I love this application and cannot believe I waited so long to start using it. With VirtualBox, I am able to ‘play’ with new installations of Ubuntu (and other Desktop Environments), all the while leaving my daily driver alone. I am using Ubuntu 20.04 and do nothing to mess up that installation. I keep it up to date, and install some third party applications, but for the most part I leave it alone.
I recently downloaded a daily build of “Jammy Jellyfish” and installed this in a virtual machine. I run sudo apt update/upgrade at least once a day. Running an alpha version (maybe it's a beta?), is not for everyone, even if it’s done from a virtual Machine (VM). I have found that updates do sometimes break the install, and I have had to reinstall in the VM twice so far. This is why I would never use the daily build as my daily driver. Too much at stake.
But it’s thrilling to me to have a glimpse into the future of Ubuntu by having Jammy installed in the VM. In addition to filing bugs I find in Jammy, I also install my favourite apps and themes etc. After all, what I really am doing is seeing into the future, and whether or not all my favourite things about Ubuntu still work. There are still many months of development before Ubuntu 22.04 is released in April, so much fun to be had with new features and new applications on a regular basis. I am very pleased so far, and I thank the devs who work on Ubuntu to make it truly a World class Linux distribution.
