"Failed to synchronize cache for repo 'couchbase-server', disabling" and 2 more messages on fedora 24

hello experts,
i tried to install couchbase SDKs on my fedora 24 and follow Start Using the SDK manual, but i encountered below messages when tried to run

dnf install -y install libcouchbase-devel

Failed to synchronize cache for repo ‘couchbase-server’, disabling.
Failed to synchronize cache for repo ‘couchbase-sdk’, disabling.
Failed to synchronize cache for repo ‘couchbase-server-community’, disabling.

what can i do?

Thanks.

I’m not sure we actually support fedora. @avsej - I think you use fedora, do you have any ideas about this?

vey bad news,it means you are omitted , all fedora users?
then what shall i do?

You can certainly use the C library if you compile it form source. I just don’t know if it will work with package managers. Did you follow installation instructions for installing the repository itself? http://developer.couchbase.com/server/other-products/release-notes-archives/c-sdk

@vhp1360 check your /etc/yum.repos.d/libcouchbase.repo and remove all other couchbase-related repos

You should have something like

[couchbase]
enabled = 1
name = Couchbase package repository
baseurl = http://packages.couchbase.com/rpm/7/x86_64
gpgcheck = 1
gpgkey = http://packages.couchbase.com/rpm/couchbase-rpm.key

Hi @avsej ,
It is worked.

Thanks
