J it only takes a minute:
and followed the process. Since then I am unable to perform updates, installation etc from both yum and dnf.
This is the error I get from DNF
Abhinav@localhost ~$ sudo dnf update
[sudo] password for Abhinav:
Error: Failed to synchronize cache for repo 'fedora' from
Cannot prepare internal mirrorlist: Curl error: Timeout was reached
[Connection timed out after 120002 milliseconds]
and this is the error I get when using YUM
Abhinav@localhost ~$ sudo yum update Loaded plugins: langpacks
One of the configured repositories failed (Fedora 21 - x86_64),
yum doesn't have enough cached data to continue. At this point the
safe thing yum can do is fail. There are a few ways to work
"fix" this:
1. Contact the upstream for the repository and get them to fix the problem.
2. Reconfigure the baseurl/etc. for the repository, to point to a working
upstream. This is most often useful if you are using a newer
distribution release than is supported by the repository (and the
packages for the previous distribution release still work).
3. Disable the repository, so yum won't use it by default. Yum will then
just ignore the repository until you permanently enable it again or use
--enablerepo for temporary usage:
yum-config-manager --disable fedora
4. Configure the failing repository to be skipped, if it is unavailable.
Note that yum will try to contact the repo. when it runs most commands,
so will have to try and fail each time (and thus. yum will be be much
slower). If it is a very temporary problem though, this is often a nice
compromise:
yum-config-manager --save --setopt=fedora.skip_if_unavailable=true
Cannot retrieve metalink for repository: fedora/21/x86_64. Please
verify its path and try again
I even emptied all the repos in /etc/yum.repos.d except for the original 3 repos you get when you install distro.
Please help.

Formatted my laptop and re-installed Fedora 21. After 3 sudo dnf updates. I am stuck with this problem again.
This time i didn't follow the steps on the previous article.
On further google search I found
which talks about same error. It is closed but I can't find a proper solution again.

If you sit behind a proxy, you have to configure dnf accordingly. (Even if the user's proxy settings are fine, you have to set them for dnf anyway.) The dnf settings are stored in /etc/dnf/dnf.conf. The syntax is:
proxy=&protocol&://&ip or name&:&port&
If this is not your problem, try to download the metadata with the browser to ensure, that your network connection to the url is working.
The file to receive should be an xml file. If you cannot download the metadata via the browser, chances are, that either port 443 (for https) is blocked or there is something wrong with your internet connection.
