IIRC this has been converted into an core extension with Joomla 4 so there is no dedicated 4.x version. I have not checked yet whether the upgrade just replaces the old version so it could be filtered out here or is defined to be compatible with 4.0 in the update server.

I'm checking at the moment what happens when I ignore the message.

• Before migration: version 2.1.2 with extension_id 10003.
• After: version 1.1.1 (which is a bit weird but I don't care) with extension_id 10039.
• • Old plugin 10003 is uninstalled from db
• • old update server is removed from db
• • plugin works

Ok lets go and update the update server: https://appscdn.joomla.org/webapps/jedapps/webinstaller.xml to "claim" that 2.1.2 is supported in 4.0 too. It will be replaced by the update anyway and filtering it out would just add confusion i guess, now we have to find out where the file can be found and updated. Maybe @rdeutz does know which server this file comes from? Its not part of the repo: https://github.com/joomla-extensions/install-from-web-client

After: version 1.1.1 (which is a bit weird but I don't care) with extension_id 10039.

I guess the Core version should just be 4.0.0 right @wilsonge ?

Found PR done here: joomla/install-from-web-server#59

I guess the Core version should just be 4.0.0 right

I think it must be higher than 2.1.2 at least. Otherwise you'll get an update message in Joomla 4 with changes in joomla/install-from-web-server#59

Didnt you said the update server is gone on Upgrade to 4.0.0

You're right

The update server has been updated so i would like to close here ok @ReLater ?

With tears in my eyes I see an update message in Joomla 4 for version 1.1.1 to 2.1.2.
With an update server that can't be found in "Extensions: Update Sites".
When I click "Rebuild" there the update message is gone.
I'm really confused and sorry that I gave wrong informations above(???).

So I repeat your question to @wilsonge : "I guess the Core version should be 4.0.0 right?".

In https://appscdn.joomla.org/webapps/jedapps/webinstaller.xml:

Can we change the block with <targetplatform name="joomla" version="4.*"/> to <version>1.1.1</version> or lower (some dummy nonsense) instead now <version>2.1.2</version>?

i think that is "easier" (2 days before J4 stable) than changing the webinstaller version in J!4 core.

But ???????????????????????????????????????????????? By now I am too confused and tired to understand...

i think that is "easier" (2 days before J4 stable) than changing the webinstaller version in J!4 core.

the cleanest way would be to update the version shipped with the CMS to 4.0.0 changing the version on the update server XML can be done too but changing the version in the CMS should and can be done for 4.0.0 anyway. I can prepare the PR later.

PR: #35127

Can we change the block with to 1.1.1 or lower (some dummy nonsense) instead now 2.1.2?

Well that would mean we claim that only a lower version than the installed right now is compatible with 4.0 and that will only confuse people cause that would show up as "updates required" thats why i used the last stable to claim 4.0 compatibility.

Closing as there is a PR #35127
