我在 20.04 LTS 上安装 Ubuntu-pro 失败（不小心按了软件更新程序上的营销按钮），现在纠正这个问题的努力导致 ubuntu-advantage-tools 和 ubuntu-pro-clients 之间出现依赖冲突。有人遇到过同样的问题吗？有明显的解决办法吗？Aptitude 运行了几个小时然后停了下来。

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
ubuntu-advantage-tools : Depends: ubuntu-pro-client (>= 31.2~20.04) but it is not installed
ubuntu-pro-client-l10n : Depends: ubuntu-pro-client (= 31.2~20.04) but it is not installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

编辑：建议删除 ubuntu-advantage-tools，但这并不能解决这个问题，因为此功能不容易删除。
