I would like to upgrade from 20.10 to 21.04. But do-release-upgrade returns "no new release found".

/etc/update-manager/release-upgrades:

Prompt=normal

$cat /etc/lsb-release

DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=20.10
DISTRIB_CODENAME=groovy
DISTRIB_DESCRIPTION="Ubuntu 20.10"

I executed following steps:

  1. sudo apt update
  2. sudo apt upgrade
  3. sudo apt dist-upgrade
  4. sudo apt autoremove
  5. sudo do-release-upgrade

but last steps returns "no new release found".

Do you have any hints what to check next?

    The release of 21.04 specifically has been delayed because of a critical bug. See the mailing list post at https://lists.ubuntu.com/archives/ubuntu-devel/2021-April/041448.html for information. – aws May 06 '21 at 04:03

If I remember correctly, Ubuntu version upgrades are not rolled out to everyone at once, and are done so steadily within about a week's time frame, to ensure that if some major breaking bug is discovered, Canonical can halt the upgrade until it is fixed, and not everyone becomes affected by said major breaking bug

  • It's not a specified time (about a week), yes there are weekly team meetings where it's commonly discussed (if not already out), but it's addressed more often than that – guiverc Apr 25 '21 at 11:30

    @guiverc I was talking about general time frame after a new version has been released, for users being able to upgrade to it (LTS to LTS aside) – easthighNerd Apr 25 '21 at 22:22

    Fair enough... but I do recall upgrades taking much longer than a week (even ignoring LTS releases) and not your "within about a week's time frame". I would agree the norm is about a week though; or a few days over fitting your wording.. but I'd have preferred "usually" or more qualification (to allow for longer even if hopefully not anticipated). Still a good answer and upvoted. – guiverc Apr 25 '21 at 22:39
