How do I install apps on my iPod if it goes to installing then stops?

I'm having this same issue across all my devices. Same JMS error on the Mac.

Same here across all devices nothing will install or update.

Actually new purchases will download install. Cannot install updates or re-download previous purchases.

I also have this across multiple devices. iOS 6.1. I have signed out of the App Store and back in, powered off all to no avail. If I delete an app (and all associated data) then a while later it will install as a new app.

I haven't had luck with this. And my iPhone now has 9 updates available. This is pretty impractical. Apple needs to do something...

I have had some luck on one of my iPads and one iPhone that if I keep hitting install sometimes it will install the app.

It seems to be more successful if I sign out of the app store, close it out completely and then go back in, select the app icon, not the update button, then hit update a number of times from the app page.

I've had some success this way. Got 5 updates on my iPad to work that way last night but my iPhone wouldn't. But today I got 5 of 6 updates on my iPhone to work this way. Not a great solution but until Apple comes up with a fix it might work if it's something you need right away.

Would be nice if they would post some kind of update. I do know there are some people that are not having this problem. Checked with some co-workers and they are fine.

Ok not sure if they implemented a fix but all of a sudden my updates are working on all my devices!

Hopefully a fix is in place.

Mine are working now too. I tried downloading one update at a time in iTunes and that was working so I did update all and THAT worked. So then I tried on the various devices and voila.
