No available releases found

8.8.3 probably should have shipped with a post_update function to reset the Update manager's cache of fetched data and ensure that sites automatically try to re-fetch available updates. The URL changed where Update manager is fetching info. See #3074993: Use "current" in update URLs instead of CORE_COMPATIBILITY to retrieve all future updates. But the post_update didn't happen, and it's going to be weeks before another 8.8.x release that can help any of this, so there's not much more to do here. If you have trouble, click 'Check manually'. /shrug

Sorry,

Very unlikely since @AlenaSystems didn't mention it but it could also happen if you were running an alternative update server and the format was update to match changes in #3074993: Use "current" in update URLs instead of CORE_COMPATIBILITY to retrieve all future updates

I ran into this as well and still having this problem on 8.9.1. I am not using an alternative update server. "Check for updates manually" does not help. Cache rebuild does not help. I haven't been able to figure out how to get the module working again.

Releases ARE shown for:

• pantheon_advanced_page_cache
• google_tag
• datalayer
• config_split
• config_readonly
• config_ignore_readonly

No releases are shown for core or for these modules:

• admin_toolbar
• adminimal_admin_toolbar
• autocomplete_deluxe
• classy_paragraphs
• config_filter
• config_ignore
• config_update
• csv_serialization
• ctools
• devel
• dropzonejs
• empty_fields
• entity
• entity_browser
• entity_browser_enhanced
• entity_reference_revisions
• field_group
• field_permissions
• flag
• honeypot
• inline_entity_form
• linkit
• markup
• metatag
• paragraphs
• pathauto
• redirect
• redis
• scheduler
• shariff
• simple_sitemap
• smart_trim
• social_media_links
• svg_image
• token
• viewsreference
• webform
• adminimal_theme

I don't see any pattern to which modules have releases shown.

+1 for this issue. I'm having the same problem, and finding this was a relief because I thought I was going insane.

If it wasn't for the fact that some of the projects are able to successfully fetch update information, I'd suspect this to be a network issue... like the web server can't reach d.o or something. But Since some projects are fetching updates, I'm less sure of that.

We got similar experience as @jdleonard.

It got worked after I deleted some entries from "key_value" table with this query:

DELETE
FROM `key_value`
WHERE `collection` = 'update_fetch_task'

Given #7, this is almost certainly duplicate with #2920285: Update module can get 'stuck' with 'no releases available'. Let's continue over there.

Thanks,

I had the same symptoms, but for me the workaround in #7 did not help. In my case it turned out to be a config problem. I noticed that on the settings page (/admin/reports/updates/settings) all form fields were empty. After selecting some settings (I chose "Weekly" and "Only security updates", but I guess it doesn't matter what you pick) and saving the form, things started to work as expected.

The cause of my broken config may be syncing of databases between environments - I'm not sure. I don't even think this qualifies as a bug, but I wanted to leave my solution here as a tip for anyone with similar problems.

ran into this today on a locally hosted site not installed with composer and can confirm that the advice in #7 corrected the issue.

#7 worked like a charm!

#7 did it for me except for checking updates for Drupal Core. As in #9, there weren't any settings enabled on the /admin/reports/updates/settings page. So selecting a few options there made the available updates checking again for Drupal Core updates.

#7 - Thank you!!!

#7 worked for me - thanks!

Confirming #7 worked in my case as well.

Executed the following code in command line with drush php:

$res = \Drupal::keyValue('update_fetch_task');
$res->deleteAll();

Thanks again for the help!

#7 worked :) thanks

#9 worked for me on several sites. - Thanks!

#7 worked for me (after hours of searching) - THANKS!!!!

#7 worked for me as well. Thanks

#9 worked well in a couple Drupal 9 sites

#7 worked for me. Thanks a lot.

Ditto - #7 worked for me on a few sites - this issue keeps reoccurring for me. Many thanks :)

#9 worked in my situation

With 9.2.11

Yes, hours searching for fix for this.. for me, it was working on server but not on my local (with same db). #7 on my local fixed the issue.

On server it was also busted but different solution. In Settings, neither daily or weekly was selected. Once one of these was selected - it worked (didnt work on my local).

Certainly bugs in the update module.

On Drupal 9 (after Drupal 8 to 9 Upgrade) #7 only fixed it for some hours for us, I now tried re-installing the "Update Manager" module, let's see, if it fixes things permanently.

Drupal 9.3.15, #7 worked for me as well. Thank you!

Thank you #7, worked for me Drupal 9.3.10

Again, #7 helped me today!

#9 worked for me, thanks.

#7 works for me!

#7 still working for me
