CentOS 7ホームサーバーでDebian 11 VMを実行しようとしていますが、virt-installでこの問題が発生しました。

virt-installを単独で実行しようとしたときに発生した問題については、以下を参照してください。使用するすべての構成で試しても同じ問題が発生します。

/usr/lib/python2.7/site-packages/requests/__init__.py:104: RequestsDependencyWarning: urllib3 (1.26.9) or chardet (2.2.1)/charset_normalizer (None) doesn't match a supported version!

主な問題も強調表示されています。/usr/lib/python2.7/site-packages/requests/__init__.py:104: RequestsDependencyWarning: urllib3 (1.26.9) or chardet (2.2.1)/charset_normalizer (None) doesn't match a supported version!

pipがうまくいかないようですので、以下も動作しません。

pip install --upgrade urllib

完全に詰まってどのように進むべきかわかりません。

私の主な目標は、このソフトウェアを実行することです。https://github.com/ab77/netflix-proxyCentOS 7サーバーのみを設定し、Debianを使用してシステムを再インストールする予定はありませんが、誰かより良いソリューションがない限り、シミュレーションを続行する予定です。
