Is there perhaps another repo that we can add where the packages have been approved already?

All the extra EPEL packages were put in a core ClearOS repo for now... it's just the sane thing to do until version 7.4. The workflows in ClearOS 6 and ClearOS 7 are very different and we definitely ran into a few bumps in the road!

Thanks Peter.

Is there anything we need to do to get past these issues. I see you say it was resolved. And indeed Mail Antispam now installed.

When I try to install Mail Greylisting i still get the following error.

Updating repositories and preparing package dependencies... this may take a few minutes.

Then it fails with

Exception: [u'ERROR with transaction check vs depsolve:', 'postgrey >= 1.33-2 is needed by app-greylisting-core-1:2.1.6-1.v7.noarch']

Is there perhaps another repo that we can add where the packages have been approved already?

The problem was resolved.

Short version: it was a versioning issue in the EPEL repo manager.

Long version:

Red Hat is very disciplined when it comes to keeping package versions stable. For example, RHEL 7.0 (and ClearOS 7) shipped with PHP 5.4.x and that's the version that Red Hat will maintain. Security and critical bug fixes are still backported, but you won't be surprised by a major version upgrade.

EPEL, on the other hand, is more wild west when it comes to package versioning. For example, the ClearOS ownCloud app shipped with EPEL's 8.2.4 release. Out of the blue, EPEL bumped the ownCloud release to version 9.x. That's okay, but there are always upgrade gotchas in major releases and we need time to review. The clearos-epel repo is a mirror of EPEL, but with some ClearOS related packages held back:

- BackupPC-*
- apcupsd-*
- fail2ban-*
- imapsync-*
- openvpn-*
- owncloud-*
- perl-Net-Server-*
- php-sabre-dav-*
- php-sabre-http-*
- proftpd-*
- transmission-*

We still ship these packages, but we hold back the most recent updates until we get a chance to verify new versions.

BTW, the same methodology is used for clearos-centos, but that list of packages is almost always empty. Samba was the only recent exception - some of you might recall that the upstream fix for Badlock was... not a good one.

I'm Having the same issues. 2nd fresh install that i did with the latest ISO for 7.2 and they all fail with various market place apps.
The System is up to date.
