Eclipse Check for Updates says "The operation cannot be completed" - eclipse

I tried to update Eclipse Version: 2021-09 (4.21.0) to the latest release and getting the following failure -

Actually I didn't install "M2E - Maven Integration for Eclipse" manually, it is packaged with "Eclipse IDE for Enterprise Java and Web Developers". As suggested I uninstalled it. Now I am getting the following failure -

What am I supposed to do or uninstall? I think it is another plug in or something that's causing a conflict

Why is Eclipse not letting me install new updates?

I’m using the following version of Eclipse on Mac 10.9.5
Eclipse Java EE IDE for Web Developers.
Version: Juno Service Release 2
Build id: 20130225-0426
When I click on “Help” -> “Check for Updates”, I get the “Available Updates” dialog
The operation cannot be completed. See the details.
Cannot complete the install because one or more required items could not be found.
and there is only a “Cancel” dialog. When I click “Cancel,” a smaller dialog appears with the message
Some sites could not be found. See the error log for more detail.
and when I click the “Details” button, I get
Some sites could not be found. See the error log for more detail.
No repository found at http://download.eclipse.org/mat/1.3.1/update-site/.
Unable to read repository at jar:file:/Users/davea/Downloads/ehep-1.0.0.zip!/site.xml.
error in opening zip file
At this point, I don’t know what else I need to do to successfully install updates or correct the existing problem.
Edit: Following the suggestion, I fixed the broken repositories, however, now when I get the Available Sites dialog, I only check the
Eclipse IDE for Java EE Developers
option, yet I still get these errors, complaining about conflicting dependencies. How do I get around these?

When you open http://download.eclipse.org/mat/1.3.1/update-site/ in a browser, it says that it moved to http://archive.eclipse.org/mat/1.3.1/update-site/. Maybe you can try this.
I haven't tried this, but it seems like you can configure the Update Site location using Window -> Preferences -> Install/Update -> Available Software Sites, and there finding and replacing the above location.
About that other error: Seems like you added some local archive site some time ago and since then deleted or moved that archive. If you still need it, try to restore it, otherwise use the above preferences to remove it.
Having said that, it might be a good idea to move on to a newer version of Eclipse...

Using Eclipse Indigo.
I installed the STS plugin first.
Then when I attempted to install the Jboss tools plugin. I received the same error.
I unchecked JBoss Central Community, and JBoss Tools Common - Mylyn. Pressed Next (no errors this time).
After doing so you have to restart the IDE. You should now have both plugins.
Please TRY
Eclipse 3.7.2 Platform Runtime Binary INDIGO SR2 IDE for JAVA EE DEVELOPERS
And then go for JBOSS tool.

Groovy code is not highlighted

I downloaded the Eclipse directly from eclipse downloads page - the Eclipse IDE for Java EE Developers and unzipped it
however, when I open .groovy file, its not highlighted. I tried to download and run Groovy plugin from this page
During installing, the eclipse tells me, that groovy is already installed:
Cannot complete the install because of a conflicting dependency.

But the code is still not highlighted... Can you tell me what next steps should I try to get the code highlighted?
The most likely cause for this is that you are editing your groovy file in a Java editor.
Reopening the groovy file fixed it for me.
