坐下来工作做例行工作apt update && apt upgrade并遇到一些问题ubuntu-advantage-tools。
我不确定这个包是做什么用的，但它是随 Ubuntu 20.04.2 LTS（GNU/Linux 5.4.72-microsoft-standard-WSL2 x86_64）一起提供的。
我尝试了常规方法apt purge并尝试再次安装，但仍然没有成功。

我只是展示了安装的例子，ubuntu-minimal因为（我认为）这是唯一依赖于的东西ubuntu-advantage-tools，而删除ubuntu-advantage-tools也会删除ubuntu-minimal。
我可以重新创建我的 Ubuntu WSL，但这有点麻烦。我没有得到 Canonical 的商业支持，我需要担心这个包有问题吗？ubuntu-minimal实际上，我更担心那个元包被破坏。
谢谢！
我最终“重置”了我的 WSL Ubuntu 安装，执行了初始“apt update && apt full-upgrade -y && apt autoremove -y”，错误再次出现。也许 Ubuntu 现在有一个有缺陷的软件包？

答案1
就我的情况（Ubuntu 18.04）而言，这导致了一个问题，因为该包需要一些未安装的 Python3 包，而 apt 无法完成安装。
对我来说，解决方法是删除 ubuntu-advantage-tools 来安装 python3 包，然后重新安装
要从 apt 中硬删除 ubuntu-advantage-tools 引用：
sudo mv /var/lib/dpkg/info/ubuntu-advantage-tools* /tmp
答案2
ubuntu-advantage-tools 升级配置失败 错误 #1938097
sudo vim +295 /var/lib/dpkg/info/ubuntu-advantage-tools.postinst
# or use gedit, nano, or else
改变295 行到
cloud_id=$(cloud-id || true)
进行此更改然后
run dpkg --configure -a
另一种解决方法是卸载 cloud-init 包。如果没有安装此包，则无法找到 cloud-init，因此不会发生错误。
