我想使用命令行从 Ubuntu 18.04.6 LTS 升级到 20.04 LTS。首先我做了这些命令sudo apt update && sudo apt dist-upgrade -y && sudo apt install -f && sudo dpkg-reconfigure -a，这些命令执行没有错误。执行命令sudo do-release-upgrade导致意外错误：
发生致命错误
请将此报告为错误，并在报告中包括文件 /var/log/dist-upgrade/main.log 和 /var/log/dist-upgrade/apt.log。升级已中止。您的原始 sources.list 已保存在 /etc/apt/sources.list.distUpgrade 中。
