この時の環境は、次の通り。
1. certbot-1.22.0-1.el8.noarch
2. Python 3.6.8
3. pip 9.0.3
4. RHEL 8.6

cerbot、Python 3.6の更新を行ってみた。
もともと最新版になっていたようで、例外発生時と状況は変わらず。
次のコマンド実行が効いたようです。

[root@hoge-inet hoge]# pip3 install --upgrade pip [root@hoge-inet hoge]# pip3 --version WARNING: pip is being invoked by an old script wrapper. This will fail in a future version of pip. Please see https://github.com/pypa/pip/issues/5599 for advice on fixing the underlying issue. To avoid this problem you can invoke Python with '-m pip' instead of running pip directly. pip 21.3.1 from /usr/local/lib/python3.6/site-packages/pip (python 3.6) |
pip ? のバージョンが、”9.0.3”から”21.3.1”に更新されたようです。
正直、何がなんだか、よくわかりません。
なんで効果があったのかよくわかりませんので
その時の実行ログを下に添付します。
