Updating Intel iSeries 16Gb Computer from Ubuntu 16.04 64 bit to Ubuntu 18.04 64 bit

[Pete]

I am doing this vivo on the console rather than remotely using SSH like I did for the Pine64 2Gb computer.

Previous to this have upgraded 3 laptops (16Gb) and desktop (32Gb) to Ubuntu 18.04 / Windows 10

IE: been running these now for over a month and they are doing well.

1 - shut down Oracle VB
2 - shut down Homeseer 3

3 - via terminal window
4 - sudo su
5 - sudo apt update && sudo apt dist-upgrade

HS3Pro:/home/pete# sudo apt update && sudo apt dist-upgrade
Calculating upgrade... Done
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

6 - sudo apt install update-manager-core

update-manager-core is already the newest version (1:16.04.13).
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

7 - do-release-upgrade -d

First attempt was fast and full of errors. Probably because I was using VNC to access the desktop.

2nd attempt at update looks good so far. This was done on the desktop via a terminal session.

This computer was updated from Ubuntu 14.04 to Ubuntu 16.04 a couple of years ago.

Might purchase a new SSD (faster one) and install Ubuntu 18.04 on it replacing current SSD after this one is running.

Desktop changes with Ubuntu 18.04 had to be fixed. Really it was only the network manager and I rarely use the desktop.

Homeseer 3 and Oracle Windows VB is working fine.

Had an issue with a slow boot and reboot. This is a documented bug in Ubuntu 18.04.

HS3Pro:~# systemd-analyze blame

5.450s networking.service
5.215s stunnel4.service

Still booting a bit slower than when running Ubuntu 16.04.

Here is the system boot on the Pine64 - which is a bit slow using the microSD

A standard update of Oracle Virtual box 5.2 today disabled the functioning of Oracle VB. This relating to old and new libraries. Tinkering with it for some 30 minutes of updating and clean up decided to remove Oracle Virtual box 5.2 and install standard release Oracle Virtual box and it is running with no issues. I did have similiar issues with updating Ubuntu 14.04 to Ubuntu 16.04 and Oracle a couple of years back. I keep writing that I am going to start from scratch here with endeavor and have not as Homeseer 3 Pro appears to be running just fine.
