Ubuntu – Ubuntu 17.10 doesn’t show up in update-manager


I have a laptop with Ubuntu 17.04 desktop installed.
And I noticed that Ubuntu has just announced their new version (17.10). However, when I'm trying to open update-manager, it just tells me that I have the newest version.

Also, when I type the sudo do-release-upgrade command on the terminal, it tells me the same thing (No new release found.)

Is there any reasons for that, and what can I do? or should I just wait for that version, to get to the server?

Be Patient

This happens every six months with the next release of Ubuntu.

Availability does not begin at 00:01 local time. It happens worldwide at once...after the mirrors are updated. So go about your normal life.

Due to phased updates and the system-to-system variation of apt's normal checking for updates, you may not get notification of a new release for a few days.

  • If you still don't get notification, check your Software & Updates Control Panel settings. Some users forget that they disabled new-release notifications, or enabled only LTS-release notifications.

There is wide, friendly disagreement on whether upgrading or reinstalling is "best". Both are thoroughly tested. Both work. They are a matter of user preference, with the following caveats:

  • Backup your data before doing either.
  • If you upgrade, uninstall all software from non-Ubuntu sources (including PPAs) - they cause most upgrade failures.

Upgrading to a new release is different from Debian. Use the Ubuntu release-upgrade tool (do-release-upgrade). Following Debian instructions (apt dist-upgrade) will install new packages...in your older release.

If you are offered a partial upgrade, refuse it...which will abort the upgrade entirely and return you to the older release of Ubuntu. Your upgrade is broken, usually because of non-Ubuntu packages on your system. Disable those sources, uninstall those packages, and then try the release-upgrade again.

If you use proprietary or compiled drivers (like for some video cards), you may need to recompile or to install updated versions to match your new kernel. Make sure you have those instructions on hand before starting the release-upgrade.
