我已经有一个月左右的时间遇到这个问题，它让我陷入困境，如果这个问题有一个简单的解决方案，请原谅我。我已经尝试了几乎所有可能的解决方案。
我无法打开软件和更新，也无法使用：
sudo apt-get remove software-center
这再次告诉我们使用
sudo apt-get -f install
我想安装 brew (以更新 dart)，因此我尝试了这个命令：
$ sudo apt install linuxbrew-wrapper
sudo: unable to resolve host ice

linuxbrew-wrapper is already the newest version (20150804-3).
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
python3-magic : Depends: libmagic1 (< 1:5.25-2ubuntu1.1~) but 1:5.25-2ubuntu1.1 is to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
$ sudo apt-get -f install

几乎每次安装软件都会出现同样的错误。所以我对此无能为力。

sudo apt dist-upgrade也解决不了问题。
此外，我的屏幕上已经出现这个警告大约一个月了，我该如何处理？
