apt-get clean 中出现“问题解除链接”错误

Question

每当我尝试使用时都会出现问题sudo apt-get clean：

:~$ sudo apt-get clean
W: Problem unlinking the file apt-fast - Clean (21: Is a directory)
:~$ apt-fast clean
W: Problem unlinking the file apt-fast - Clean (21: Is a directory)

清除 apt-fast 并运行 sudo apt-get clean 是我发现解决此问题的唯一方法。
但是我用apt-fast了很多，所以不使用它不是一个好的解决方案。
重新安装apt-fast 并运行sudo apt-get clean使问题再次弹出。

另外，在安装时（我不知道这是否有用），我发现了这个问题：

Unescaped left brace in regex is deprecated, passed through in regex; marked by <-- HERE in m/\${ <-- HERE _MAXNUM}/ at /tmp/apt-fast.config.NDgAmi line 205.

我也在使用 Ubuntu MATE 16.04。

谢谢。

一个潜在的解决方案是/var/cache/apt/archives/apt-fast每次要运行apt-get clean.

$ rm -r /var/cache/apt/archives/apt-fast

这也意味着您正在清除apt-fast.
