Docker：无法从损坏的拉取中删除中间映像

Question

有一个损坏的图像阻止了进一步的拉动。我无法删除或删除它

我做了什么：

- stopped all containers ("docker ps -a" shows empty list)
- cleaned everything with "docker system prune -a")
- "docker image ls -a" shows an empty list

当我基于 PHP7.3 提取某些内容时，出现以下错误：

$ sudo docker pull wordpress

我想知道“已经存在”：如何删除它们？（我已经尝试过 prune -a ；见上文）

我希望我可以删除所有（100%）图像 -> 这样我就可以重新下载。

（背景：硬件有内存错误。也许这就是现在出现此错误的原因。硬件和磁盘现在都正常。）

• 停止docker服务

• 删除 /var/lib/docker
