Android ADT 23 Update - Cannot complete the install because of a conflicting dependency

Question

First, ADT update errors are frequently asked but I have tried to do everything mentioned in those other Question-threads but no success (with https and without, ADT23.zip download too).

This is what I got when trying to update:

Cannot complete the install because of a conflicting dependency.
  Software being installed: Android DDMS 23.0.0.1245622 (com.android.ide.eclipse.ddms.feature.feature.group 23.0.0.1245622)

  Only one of the following can be installed at once:

How can I solve this?

Answer 1

I was facing the same issue and resolved it by uninstalling the previous version of ADT completely and then installing the new version.

Try it out.

Answer 2

It works for me :)

If for some reason you installed an ADT preview and need to revert back to the current stable, you can't use the dialog to install "new" software since what you want is actually an older one. Instead do this:

• Open Help > About Eclipse... on Windows or Linux. On Mac, use the app's menu > About...
• Click the "Installation Details" button.
• Select the "Installation History" tab.
• Select one of the previous configurations.
• Click the "Revert" button at the bottom.
