Application installation is unavailable because another operation is running: Committing update set: <update set name>

[Travis DePuy]

I'm trying to upgrade one of the apps we installed from the store, but when I go to the "All Applications" page, I get this message and the screen refreshes itself every 10-15 seconds:

The update set it is referencing has been committed. It is an update set that was developed in the application scope of this app I'm trying to upgrade. 

I saw these other posts about this error:

But the resolutions were either reset and wipe the instance or otherwise not helpful for me. 

Is there a background process that might be stuck? I don't see anything relevant in the system logs, but I could be searching for the wrong things. 

Ideas?
Happy Friday!

Hey Travis,

Do you have a domain separated plugin installed on this instance? if yes, then this is a known issue and the workaround is to upgrade the app/activate the plugin from the global domain. This issue is fixed in Orlando release.

I don't think it is domain separated, but I'm not really sure where to look. In looking at the domain_list table, I just see the "Default" domain. The "Domain Map" in the system menu doesn't display. 

¯\_(ツ)_/¯

Well, I had requested an upgrade to Orlando and that seemed to have fixed it. So I'm guessing some background process was stuck and needed kicking.

Same for me - an in family upgrade did the job
