我尝试在 Linux 虚拟机上运行 apt-get update 并且一个接一个地得到相同类型的错误。此外，我在同一行中说“文件具有意外大小”，我也不确定它的来源。
注意:这适用于 Windows 机器，但不适用于我的 Mac。
任何帮助表示赞赏!
最佳答案
我遇到了同样的问题，原因是我在我的 iPhone 上设置了内容限制，这些限制会自动同步到我的 Mac。
关闭限制后，一切正常。

关于macos - 在 Mac 上的 docker ubuntu 镜像上运行 apt-get update 会导致 "File has unexpected size"，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/66200219/
