Help->Check for updates
shows me 2 items
I deselect the first one and I cannot pass beyond the second Next
To workaround, I must select all.

Reproducible: Always

Steps to Reproduce:
1. simple: Here you need to get an eclipse 4 that is not latest and that shows the latest eclipse in Help->Check For Updates(CFU), so that you can potentially upgrade to the latest Eclipse SDK via that CFU.
I guess you need to add,
The Eclipse IBuild Updates - http://download.eclipse.org/eclipse/updates/4.1-I-builds
that site to Available Software Sites, else CFU doesn't see the latest eclipse build

details:
get previous to last eclipse 4 sdk from like here: http://download.eclipse.org/e4/sdk/
in my case it's: 
for some reason with this eclipse (previous to last) it didn't work:P http://download.eclipse.org/e4/sdk/drops/I20110526-1435/index.php

this bug was tested with: eclipse-SDK-I20110518-2200-win32-x86_64.zip but I am also retesting it with that one.


2. simple: run eclipse with jre6u25 (didn't try with jre7)
details:
ie. unpack and run, for me it's running with this eclipse.ini but probably there is no need to run it like this, just maybe make sure it's not running with jre7

-startup
plugins/org.eclipse.equinox.launcher_1.2.0.v20110502.jar
--launcher.library

-Dosgi.requiredJavaVersion=1.5
-XX:+HeapDumpOnOutOfMemoryError
-Dcom.sun.management.jmxremote
-Xms128m
-Xmx512m
 

3. simple: Help->Check For Updates and make sure there is an Eclipse SDK to update to, but don't update yet, cancel or something. If there are no updates, you didn't add the above url to Avail. Software Sites (this is for me when I reread this xD).

4.
simple:
install previous to last Subversive SVN Team Provider (Incubation)	aka this one: 0.7.9.I20110419-1700
This is needed so that Help->Check For Updates has at least 2 items that need to be updated (ie. eclipse sdk and SVN Incubation Provider something)

details:
Help->Install New Software, deselect `Show only the latest version of available software`
select `All Available Sites` in `Work with:` and wait for the list to update from Internet, you can type SVN before since we want to install this.


after like some minutes the list is populated, you expand Collaboration and select
this older version of SVN, called:
    Subversive SVN Team Provider (Incubation)	0.7.9.I20110419-1700
note: the new one is this (but don't install this, we need to update to it later in CFU):     Subversive SVN Team Provider (Incubation)	0.7.9.I20110523-1700

so install that old version 0419, and restart eclipse when prompted

 (just to be clear this is eclipse: 
Eclipse SDK

Version: 4.1.0
Build id: I20110526-1435
)

5. Window->Show View->Error Log

6.
Help->Check for updates
after a long while you should see two options:
Eclipse SDK
Subversive SVN Team Provider (Incubation)

deselect Eclipse SDK, click NExt, then click Next again, something happens in Progress view (like still updating some artifacts, but probably this is irrelevant)

nothing happens, you cannot go Next, but notice this error in Error Log:

To work around this, click Back and select Eclipse SDK, not Next,Next works and stuff :)


I initially wanted to check why when I updated only 3 items related to SVN while having the first one (Eclipse SDK) uncheck, it installed all of them. And since I cannot really bring back all the other old(!) SVN components such that to have them updatable in Check For Updates, I tried it only with SVN Provider and hit this bug instead. Maybe they are related.
