Ubuntu 20.04 LTS中ubuntu-advantage-tools与ubuntu-pro-client依赖冲突导致更新失败的求助

大家好，我在Ubuntu 20.04 LTS上不小心点了软件更新器里的推广按钮，导致ubuntu-pro安装失败，现在尝试修复这个问题时，遇到了ubuntu-advantage-tools和ubuntu-pro-client之间的依赖冲突。我试过用aptitude处理，但它跑了几个小时后就卡住了，有没有人遇到过同样的问题，有没有简单可行的解决办法？

执行sudo apt-get upgrade时的错误输出：

~$ sudo apt-get upgrade
Reading package lists... Done
Building dependency tree       
Reading state information... Done
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).

接着执行sudo apt --fix-broken install的错误输出：

$ sudo apt --fix-broken install

The following additional packages will be installed:

编辑补充：我试过网上建议的卸载ubuntu-advantage-tools的方法，但这个包没法直接移除，报错如下：

dpkg: error processing package ubuntu-advantage-tools (--purge):
