Fedora Core ver.20

さっそくのアドバイスありがとうございます。釣ではございません。

1つ気になったのが、「vi /etc/yum.repos.d/fedora.repo」を
編集すると下記のようなエラーが最初に出ます。

これが問題なのでしょうか?

NEWER than swap file!

(1) Another program may be editing the same file.
If this is the case, be careful not to end up with two
different instances of the same file when making changes.
Quit, or continue with caution.

(2) An edit session for this file crashed.
If this is the case, use ":recover" or "vim -r /etc/yum.repos.d/fedora.repo"
to recover the changes (see ":help recovery").
If you did this already, delete the swap file "/etc/yum.repos.d/.fedora.repo.swp"
to avoid this message.
