我照做了，并得到了这个回溯。之前我做过一些指向和指向的实验do-release-upgrade -d，但我对它们都进行了and ed 操作。upgrade-alternativespythonpython3python3python3.8sudo update-alternatives --remove-all pythonsudo apt install --reinstall
$ sudo do-release-upgrade -d

答案1
我有同样的问题。我按照以下步骤解决了它：
打开一个终端。
输入以下指令：
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启动命令：
sudo do-release-upgrade
答案2
根据https://bugs.launchpad.net/ubuntu/+source/ubuntu-release-upgrader/+bug/1874250/comments/9“这似乎通常源于 pip 安装的 distro-info 版本掩盖了 apt 版本”，你可以使用以下命令删除 pip 安装的版本
sudo python3 -m pip uninstall distro-info
sudo apt reinstall python3-distro-info
