I'm following the instructions under Get Started with the Apex Debugger. I'm up to the point where I create a Permission Set for the debugger user to enable the "Debug Apex" permission under System Permissions. Except I can't see that permission.

Do I need to do something else to access it?

Without it the Force.com IDE fails with the following error. (Which I assume is directly related to the permission I can't set)

Your user doesn't have the permission to debug Apex.

I've tried to configure this permission from both a LMA login and direct login as the System Administrator in the sandbox.

The Start Partner Debugging Session button does appear in the Apex debugger setup page. It generates a forceide: link with a valid session ID.

There isn't much to go on in the Force.com IDE Log Viewer. There is a message:

(DebuggerConnectionException) nnot connect to the remote server (Open log file for full message and/or stacktrace).

This entry doesn't appear in the force-ide.log file.

Note that this corresponds to the Debug Apex Code in Subscriber Orgs Spring '17 feature.

The required permission isn't called "Debug Apex" as it currently appears in the docs. Rather it is

Permission Name: View and Debug Managed Apex
Description: View the Apex code in your packages, and debug code with Apex Debugger, when logged in to subscriber orgs. Limited to code in Managed - Released packages.

This permission should be assigned to the user in the LMA org rather than the subscriber org.
