Yum install NOT Working

I tried install insync follow this steps:

sudo rpm --import https://d2t3ff60b2tol4.cloudfront.net/repomd.xml.key

Create a new file insync.repo in /etc/yum.repos.d/ with the following content.

[insync]
name=insync repo
baseurl=http://yum.insynchq.com/fedora/$releasever/
gpgcheck=1
gpgkey=https://d2t3ff60b2tol4.cloudfront.net/repomd.xml.key
enabled=1
repo_gpgcheck=1
metadata_expire=120m

sudo yum install insync

But i receive error:

http://yum.insynchq.com/fedora/6/repodata/repomd.xml: [Errno 14] PYCURL ERROR 22 - “The requested URL returned error: 403 Forbidden”
Trying other mirror.
Error: Cannot retrieve repository metadata (repomd.xml) for repository: insync. Please verify its path and try again

How can i fix this issue ?

@silas_i Are you using CentOS/RHEL? The repository is for Fedora only. RHEL 6 is based on Fedora 12, and we don’t support that. There are beta packages available for CentOS/RHEL in www.insynchq.com/downloads, please try them out. They’re command line clients only though.

Is there a way to download the packages you are suggesting by command line only? I cannot use GI in th emachine i need to install insync.
