Installing insync in fedora from command line

I’m simply trying to install insync in a machine from command line as:
sudo yum install insync
but I’m having the following error:

No Presto metadata available for insync
insync-1.3.12.36116-fc21.x86_6 FAILED 96% [============================================================================== ] 6.1 MB/s | 60 MB 00:00:00 ETA
http://yum.insynchq.com/fedora/21/x86_64/insync-1.3.12.36116-fc21.x86_64.rpm: [Errno -1] Package does not match intended download. Suggestion: run yum --enablerepo=insync clean metadata/s | 60 MB 00:00:00 ETA
Trying other mirror.

Error downloading packages:
insync-1.3.12.36116-fc21.x86_64: [Errno 256] No more mirrors to try.

I’ve already tried to run “yum --enablerepo=insync clean metadata” but it didn’t work.
Any ideas?
