Cannot upgrade from 2.3.0 to 2.3.1

[cybermac912]

I currently have STS 2.3.0.RELEASE (32-bit Linux) installed. When I try to upgrade using "Check for Updates", I get blocked with the following error:

Cannot complete the install because one or more required items could not be found.
  Software being installed: SpringSource Tool Suite 2.3.1.201003091003-RELEASE (com.springsource.sts.ide 2.3.1.201003091003-RELEASE)
  Missing requirement: SpringSource Tool Suite Package 2.3.1.201003091003-RELEASE (com.springsource.sts.package.feature.group 2.3.1.201003091003-RELEASE) requires 'org.eclipse.wst.server_adapters.feature.feature.group 0.0.0' but it could not be found
  Cannot satisfy dependency:
    From: SpringSource Tool Suite 2.3.1.201003091003-RELEASE (com.springsource.sts.ide 2.3.1.201003091003-RELEASE)
    To: com.springsource.sts.package.feature.group [2.3.1.201003091003-RELEASE]

Since it seems to be working for others, I'm guessing it's either a Linux-specific bug, or a misconfiguration of my environment. Is there a fix or workaround available?

Thanks

I have the same problem on Windows so its not Linux-specific.

I was able to get around the dependency problem for org.eclipse.wst.server_adapters.feature.feature.gr oup 0.0.0 by installing (via the sts interface) the WST Server Adapters package from http://download.eclipse.org/releases/galileo/

Thanks. That seemed to work.

I added http://download.eclipse.org/releases/galileo/ as an update site
Installed: WST Server Adapters 3.1.0.v200906020451
Then did a "Check for Updates"
