Cannot upgrade from 16.04 to 16.10 (No new release found)

Question

Cannot upgrade from 16.04LTS to 16.10.

Updated and dist-upgraded the system and tried running do-release-upgrade -d but it says no release found. Ensured that the prompt=normal in the "/etc/update-manager/release-upgrades" file.

Tried the same using the GUI of update-manager and changed the settings to "Notify for any new version" which is equivalent of prompt = normal and it says Your computer is up to date.

Also, all the necessary repos are present in the sources.lists.

I have recently upgraded a similar computer successfully which was quite straightforward. Cannot understand why this is happening even though the config files are similar and there are no problems in installing/updating using apt-get.

Any help would be greatly appreciated! Thanks :)

Solution

After changing the setting in /etc/update-manager/releases-upgrades from lts to normal, you need to run sudo apt-get update.

I deleted my answer because I saw that you already tried that. I did find one that might help: askubuntu.com/a/289076/231142

Open Software updater it will give you option for upgrade to 16.10

Tried, same as putting prompt = normal. No luck !

What sudo apt-get update says

Just for clarification, the sudo apt-get update forces it to check for new releases, then you do sudo do-release-upgrade.
