/bin/sh -c apt-get update -y --fix-missing' returned a non-zero code: 100

我在 jenkins 上制作镜像，遇到这个问题，我已经把 apt 源换为国内的了，但 apt-get 仍会报“Some index files failed to download. They have been ignored, or old ones used instead.”，然后我在网上搜索到加--fix-missing 参数，但我打包时还有问题“/bin/sh -c apt-get update -y --fix-missing' returned a non-zero code: 100”
