Upgrade From Ubuntu 16.04
Instructions from 18.04 Release Notes referenced above
To upgrade on a desktop system:
Ubuntu Version Notify - Long Term Only
- Open the "Software & Updates" Setting in System Settings. "System Settings" is the gear icon. "Software & Updates" are in the "System" section.
- Select the 3rd Tab called "Updates".
- Set the "Notify me of a new Ubuntu version" drop down menu to "For long-term support versions" if you are using 16.04 LTS; set it to "For any new version" if you are using 17.10. This was already set this way
Update Manager - part 1 upgrade 16.04
- Press Alt+F2 and type update-manager -c into the command box. Just open a terminal window.
$ update-manager -c
These are the issues that had to be fixed before this would work
- Error: "Failed to download repository information"
- Failed To download Repository Information Ubuntu 13-04/
This is an issue with "Other Software" (third) party items in the repository list. I solved this problem by disabling all third party repositories, in particular: ROS Kinetic, Realsense and PPA. These package must have been incompatible. Now it let me upgrade the current 16.04 system.
Follow this desktop link: Settings (gear icon) -> "Other Software" Tab. Uncheck all of them, authenticate, update and do anything else it requests.
Upgrade Manager = part 2 upgrade to 18.04
$ update-manager -c
- This time the Update Manager should open up and tell me that "the software on this computer is up to date and Ubuntu 18.04 LTS is now available. I selected the button that says upgrade to 18.04. I got info measures about some third party software being disabled.
- Error: "Could Not Calculate the Upgrade"
- Could Not Calculate the Upgrade
sudo apt-get remove ros-*
Follow 18.04 Install Instructions
