Python 18.10から19.04へのアップグレード時のエラー

Python 2.7.15+がpythonにシンボリックリンクされており、Python 3.6.7がpython3にシンボリックリンクされています。 Ubuntuを19.04にアップグレードします

Sudo do-release-upgrade

次のエラーを返します。

Ubuntuをアップグレードする前に、すべてのPythonパッケージをアップグレードしようとしました：

pip freeze --local | grep -v '^-e' | cut -d = -f 1  | xargs -n1 pip install -U

それが失敗する理由ですか？

upgradepython19.04

私はその問題を自分で解決しました。

問題のあるpythonスクリプトを見つけます：

/usr/local/lib/python3.6/dist-packages/distro_info.py

次に、それをカバーします：

https://salsa.debian.org/debian/distro-info/raw/master/python/distro_info.py

次に、Sudo do-release-upgradeを正常に実行します。
