タイトルが示すように、私はRailsアプリで作業するためにUbuntu 16.04システムをセットアップしようとしています。フォグのgemをコメントアウトすると、サーバーはローカルで起動し、gemはそのまま残されます。以下のエラーメッセージが表示されます。私と同じエラーを持つ他のユーザーを見つけることができず、必要に応じてアプリからgemを単に削除することはできないため、グーグルからは何も提供されないようです。
メッセージ全体は次のとおりです。

誰かがxmlrpcクライアントをダウンロード/インストールする方法、または問題を回避していただければ幸いです。
したがって、問題はRuby 2.4.0以降、Rubyにバンドルされる前のxmlrpcライブラリがgemに抽出されていることです。これをgemファイルに追加して、もう一度バンドルします。
gem 'xmlrpc'
