You should be able to drop to the command line and try to install it from there, probably with a:

yum install app-owncloud-business

I assume it will fail, but at least you'll be able to see the output.

I think it looks like you don't have the EPEL repository enabled. Community edition (post 30 days) uses clearos-epel, whereas Business and Home and Community < 30 days use clearos-epel-verified. The latter is enabled automatically if your system is registered to a subscription.

From Marketplace, first, make sure you have installed software repository app.

Then navigate to Cloud -> Software Repository. If you see a dash ("-") in the clearos-epel and you don't see any listing for clearos-epel-verified, this is your problem...Click on the toggle to enable the repo, then try installing the OwnCloud app again.

The clearos-epel issue fixed the issue perfectly, thank you.

A couple of other questions regarding Owncloud (please let me know if I should start a new thread for this):

- I am sharing the External Storage feature on Owncloud to share flexshares, however I have noticed that this causes clients to automatically sync everything unless explicitly told not to. Is there a way to change this behaviour at the server level so that everything is NOT shared by default to prevent automatic enormous data downloads.
- I have noticed that ClearOS 7 installs a fairly old version of Owncloud (8.2) - is it possible to upgrade this? I have run yum update to attempt this already.
