running ubuntu 18.10 as a virtual machine under macos 10.14 mojave

I’ve installed the latest Ubuntu, 18.10 Desktop, or “Cosmic Cuttlefish”, as a VirtualBox VM on my MBP. The MBP is currently running macOS 10.14, or Mojave. The version of VirtualBox in use is 5.2.20 r125813.

After an extremely limited test run I’ve found nothing out of the ordinary with this release of Ubuntu and I can comfortably say that it should run well under just about any environment, bare silicon or virtualized. One key feature in this installer that I appreciate and I’ve not seen in any earlier Ubuntu release is the ability to install a minimal desktop. This installs just the desktop, basic utilities, and Firefox web browser. This is great for a custom install for any reason, as I’ve grown tired of the kitchen sink installations where I have to go back in and run a script to yank everything off I didn’t want installed in the first place.

Because I run under VirtualBox I always build and deploy the Guest Additions inside the VM. That requires gcc and the kernel headers be installed. These tools aren’t installed with the minimal setting. To get those tools you need to run ‘sudo apt install build-essential’ at the command prompt. If you want the Tweak Tool, then you need to run ‘sudo apt install gnome-tweak-tool’. The only reason to install the Guest Additions is to share/mount a local host folder within Ubuntu, to allow the easy passing of files between Linux and macOS. The Tweak Tool allows you to select the dark theme (Yaru-dark).

So far I find the desktop is easy to live with and to use. It’s a lot flatter than all prior releases using a stock desktop theme, and I appreciate that more than older themes with their pronounced skeuomorphic touches.

As for dev tools, I have python3 (3.6.7), gcc 8.2, perl 5.26, and git 2.19.1. I might put Java on this instance as well as Go, but right now I have more than enough programming capability. My only quibble with the tools is that Python isn’t up to 3.7, but at this juncture it’s close enough. If I need the latest formal release then I’ll install it the same way I installed 3.7 on my Raspberry Pi under Raspbian.

windows 10 report – fixing an operating system update failure

I still own a Samsung Series 7 Chronos 17.3″ (NP700Z7C). I purchased it in May 2013 with 8GB ram and a 1TB hard drive. It came with Windows 8 installed. Over time I’ve replaced the HDD with a Samsung SSD, and the OS has upgraded from Windows 8 to 8.1 to 10. During the Windows 10 period I made the questionable decision to become part of the Insider’s Program (the part they call the “slow ring”). It’s been a long roller coaster ride, sometimes good, sometimes bad. I was given an opportunity to get off that roller coaster, and because of some really bad experiences, I took it. As of today I’m off.

What drove me off the Insider Program was a constant failure during the last set of pre-releases to perform a download and update. Time after time, over a several month period, updates failed. Microsoft provided no official fixes, and I went looking (i.e. “googling”) for possible solutions. Either the recommended forum solutions didn’t work or on a lot of web sites I ran into popups trying to do all sorts of mean and nasty things. I’ve got a system with all updates and I’ve got a lot of features disabled or uninstalled to harden the system’s security posture. That’s no guarantee that bad things won’t ever happen, but it does help.

To keep you from falling into the same questionable sites here’s what I used to fix the update failure problem and it comes from Microsoft and an official Microsoft web site. Go to and select Windows 10 at the bottom of the page. This will open up a new section at the bottom for Windows Update Troubleshooter. Download it, execute it, and follow its directions. If I’d found this sooner it would have saved me a week of evenings of grief.

Like I wrote above, I’m off the Microsoft Insider Program roller coaster, and I’m glad to be back on solid ground.
