I have received several notifications from my Ubuntu server running in Azure for asking me to upgrade the server to Ubuntu 18.04.1. When Ubuntu 18.04 was first released, I didn’t upgrade the server. I was afraid there could be compatibility issues and I don’t want to break the server. With the release of 18.04.1, it seems the version is stable enough for an upgrade. So I decided to upgrade the server.
Here is what I did.
First of all, I updated the server with apt update && apt upgrade, and then I backed up my server with Azure VM backup. In case upgrade failed, I can restore the VM back.
Then I ran do-release-upgrade to upgrade the server. The os kernel seemed to upgrade successfully, but the software package upgrade failed with the following output.

Upgrade complete
The upgrade has completed but there were errors during the upgrade
process.
To continue please press [ENTER]I did some search on the internet. It seems a common issue. To solve this issue, I ran the command sudo mv /usr/share/dbus-1/system-services/org.freedesktop.systemd1.service /usr/share/dbus-1/system-services/org.freedesktop.systemd1.service.bak as it is mentioned here.
After the issue was fixed, I just ran sudo apt-get dist-upgrade to upgrade all packages, and I chose to keep all local copies of configurations. After that, the upgrade completed successfully with all software and services running normally.
