Invalid package information

After updating your package information, the essential package
'ubuntu-minimal' could not be located. This may be because you have
no official mirrors listed in your software sources, or because of
excessive load on the mirror you are using. See /etc/apt/sources.list
for the current list of configured software sources.
In the case of an overloaded mirror, you may want to try the upgrade
again later.

答案1

您正在使用不受支持的 Ubuntu 临时版本。

编辑/etc/apt/sources.list文件并添加以下行：

deb http://old-releases.ubuntu.com/ubuntu disco main restricted
deb http://old-releases.ubuntu.com/ubuntu disco-updates main restricted
deb http://old-releases.ubuntu.com/ubuntu disco-security main restricted

并删除不起作用的行。

然后再次运行：sudo apt-get update。

并尝试再次进行分发升级：sudo do-release-upgrade。

答案2

为了EOL 流程，我在使用升级工具时遇到了这个错误，并花了一些时间来解决它。

检查后/var/log/dist-upgrade/main.log，我意识到镜像默认为本地区域镜像，然后失败了。此逻辑发生在DistUpgradeController.py脚本末尾附近。

原来我不得不编辑镜像路径来强制mirror.cfg脚本使用http://old-releases.ubuntu.com/ubuntu。您可以注释掉前面的其他路径，这样就可以强制使用。

瞧！
