I am running on ubuntu24.10 using kde (I guess it would be closer to kubuntu, but anyway, original installation 3 years ago was ubuntu and I installed the kubuntu stuff by hand). I want to do the upgrade to 25.04 and when I run do-release-upgrade it says that there are no new releases available.

$ grep Prompt /etc/update-manager/release-upgrades
Prompt=normal
$ sudo do-release-upgrade
Checking for a new Ubuntu release
No new release found.

Is there something I am missing?

The do-release-upgrade tool checks https://changelogs.ubuntu.com/meta-release which is a text file that's pretty easy to read...

If you jump to the bottom, you'll see for 25.04

Dist: plucky
Name: Plucky Puffin
Version: 25.04
Date: Thu, 17 April 2025 00:25:04 UTC
Supported: 0
Description: This is the 25.04 release
Release-File: http://archive.ubuntu.com/ubuntu/dists/plucky-updates/Release
ReleaseNotes: http://archive.ubuntu.com/ubuntu/dists/plucky/main/dist-upgrader-all/current/ReleaseAnnouncement
ReleaseNotesHtml: http://archive.ubuntu.com/ubuntu/dists/plucky/main/dist-upgrader-all/current/ReleaseAnnouncement.html
UpgradeTool: http://archive.ubuntu.com/ubuntu/dists/plucky/main/dist-upgrader-all/current/plucky.tar.gz
UpgradeToolSignature: http://archive.ubuntu.com/ubuntu/dists/plucky/main/dist-upgrader-all/current/plucky.tar.gz.gpg

where the key detail is "Supported: 0", which means the release-upgrade tool ignores the upgrade as it's not [yet] supported.

For status on the upgrade path, please view

https://discourse.ubuntu.com/t/status-of-oracular-to-plucky-upgrades/59652

You can look at the blocker bugs, you'll note one (last I checked yesterday) is Fix Released meaning binary packages are available for download & thus can be used; others are only marked Fix committed which means that you can't utilize that code yet (unless you download the source code, compile your own binaries & alter other code to use that instead of what's currently available for download).

I suggest waiting, and watching the Status page if you're interested in the status of the upgrade path.

If you want to force it and take a risk, you could add the -d option, and https://changelogs.ubuntu.com/meta-release-development will be used instead, but if you value stability you're still best waiting.

The Ubuntu 25.04 released thus far is for NEW installs, ie. the ISOs were released.

    It's common for Ubuntu to release the new ISOs (always on a Thursday), and the release-upgrade path often opens early the following week, however the Ubuntu Release team decide when its stable & control the open/closed status of the upgrades via edits to the files I referenced. This upgrade was actually open (Supported: 1) a number of hours, but problems were reported, thus it was closed again (Supported: 0) and is waiting for fixes for the discovered/reported bugs. – guiverc May 03 '25 at 07:02
  • I didn't touch the Ubuntu/Kubuntu detail, as I don't see a need. Ubuntu and all Ubuntu flavors such as Kubuntu, use the same Ubuntu Release Upgrader tools, so all are using the same files, all controlled by the Ubuntu Release team. – guiverc May 03 '25 at 07:06
  • It's the first time I see this.... but, hey, it's not like I run do-relase-upgrade often, right? Thanks! – eftshift0 May 03 '25 at 07:36
  • Progress appears to be happening with this... I've just received 4+ emails relating to stopped bugs, whilst status page doesn't reflect crossout yet for those, that will likely come soon, so release-upgrade maybe coming soonish too. – guiverc May 08 '25 at 01:59
  • Team members are on a Sprint currently; the taps on oracular to plucky may not open until early next week as a result... – guiverc May 08 '25 at 20:49
  • The release path mentioned in this answer is now OPEN... Check the meta-release file I mention and you'll see "Supported: 1". Refer https://changelogs.ubuntu.com/meta-release – guiverc May 14 '25 at 01:28

Continuing from the answer given by @Guiverc, I prepared a simple Python script that will list all supported or not supported versions:

#!/usr/bin/env python3


import requests, sys


def print_entry (r, s):
if (s == '') or (r.get('Supported') == s):
print(f" {r.get('Version'):<12}{'✅' if r.get('Supported')=="1" else '❌'} {r.get('Name')} ({r.get('Dist')})")


supp=(sys.argv[1] if len(sys.argv) > 1 else '')
response = requests.get("https://changelogs.ubuntu.com/meta-release")
if response.status_code != 200:
raise Exception(f"Failed to fetch meta-release data file: {response.status_code}")
entry = {}
for line in response.text.strip().splitlines():
if line.strip() == "":    # End of one release block
print_entry(entry, supp)
entry = {}
else:
key, _, value = line.partition(":")
entry[key.strip()] = value.strip()
if entry != {}:
print_entry(entry, supp)  # Last block
  • If you run this script with no parameter, it will list all Ubuntu versions together with their support status.
  • If you give parameter 1, it will list only supported versions.
  • If you give parameter 0, it will list only non-supported versions.

However, please note that the file https://changelogs.ubuntu.com/meta-release does not distinguish between "Standard Support" versions and "Extended Security Maintenance (ESM)" versions; both are reported as supported. FYI: In AskUbuntu ESM versions are not supported.
