Amazon Linuxへの他のソフトウェアをインストールする

Amazon Lightsail クラウドで Amazon Linux インスタンスを作成しました。これでMosquitto buyをインストールし、次のコマンドを入力したいと思います。

sudo yum install mosquitto

ただし、システムではこれを見つけることができません。

UPD

epelリポジトリを追加してみました。

sudo yum install -y https://dl.fedoraproject.org/pub/epel/e
pel-release-latest-7.noarch.rpm

出力を取得します。

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest
