19.04から19.10へのアップグレードに関する問題 "UnicodeDecodeError： 'utf-8' codec't cannot be byte 0x8b in position 1：invalid start byte

do-release-upgrade -dを実行し、このトレースバックを取得しました。以前は、upgrade-alternativesでpython3をpythonにポイントし、python3をpython3.8にポイントする実験をしましたが、両方ともSudo update-alternatives --remove-all pythonおよびSudo apt install --reinstalledしました。

$ Sudo do-release-upgrade -d

私も同じ問題を抱えていました。私は次の手順でそれを解決しました：

  1. 端末を開きます。

  2. 次の指示を入力します。

    wget https://salsa.debian.org/debian/distro-info/raw/master/python/distro_info.py 
Sudo cp /usr/local/lib/python3.7/dist-packages/distro_info.py  /usr/local/lib/python3.7/dist-packages/distro_info.py.old
Sudo cp distro_info.py /usr/local/lib/python3.7/dist-packages/distro_info.py

  3. コマンドを起動します。

    Sudo do-release-upgrade
