Oracular's release-specific upgrader is not working

Support and Help
1

I am on 24.04 and I wish to upgrade specifically and only to 24.10 for reasons. Yes, I know that 24.10 is EOL, but I can deal with that. Around the web, people who’ve been having trouble upgrading to/from EOL releases had success by downloading http://{archive,old-releases}.ubuntu.com/ubuntu/dists/<CODENAME>-updates/main/dist-upgrader-all/current/<CODENAME>.tar.gz, so I downloaded the one for Ubuntu 24.10 Oracular Oriole from here and unzipped it to /var/tmp/oracular. When I run

cd /var/tmp/oracular
sudo ./oracular --frontend=DistUpgradeViewText

I get

Updating repository information

No valid mirror found 

While scanning your repository information no mirror entry for the 
upgrade was found. This can happen if you run an internal mirror or 
if the mirror information is out of date. 

Do you want to rewrite your 'sources.list' file anyway? If you choose 
'Yes' here it will update all 'noble' to 'oracular' entries. 
If you select 'No' the upgrade will cancel. 

Continue [yN] y

Generate default sources? 

After scanning your 'ubuntu.sources' no valid entry for 'noble' was 
found. 

Should default entries for 'oracular' be added? If you select 'No', 
the upgrade will cancel.

    ^^^^^^^^
AttributeError: property 'suites' of 'ExplodedDeb822SourceEntry' object has no setter

This what my ubuntu.sources file contains:

Types: deb
URIs: http://us.archive.ubuntu.com/ubuntu/
Suites: noble noble-updates noble-backports
Components: main restricted universe multiverse
Signed-By: /usr/share/keyrings/ubuntu-archive-keyring.gpg

Types: deb
URIs: http://security.ubuntu.com/ubuntu/
Suites: noble-security
Components: main restricted universe multiverse
Signed-By: /usr/share/keyrings/ubuntu-archive-keyring.gpg

How do I fix this? I’m thinking I have two possible solutions:

  1. Patching the Python library file that provides ExplodedDeb822SourceEntry.
  2. Rewrite ubuntu.sources in such a way that the upgrader find valid sources in it.

#2 looks like it’ll be easier, but I don’t know where to start.

I think I am right in saying that on this platform we do not support Ubuntu releases that are end of life.

I hope I am not breaking the rule by saying: “That is not the way I would do it.”

The Support and Help section guide lists the releases we support.

That list includes Ubuntu 22.04 LTS, Ubuntu 24.04 LTS, and Ubuntu 25.10 only. No ESM, EOL or even the development release are listed there.

Ubuntu 24.10 is End of Life !

This is a follow-up to the End of Life warning sent earlier to confirm that as of 10th July 2025, Ubuntu 24.10 is no longer supported.

Thus I have closed the question, as we ENDED SUPPORT for that release. Your request is outside of Support and Help guidelines.
