When mirroring with docker build under mac, report Failed to fetch.

  docker, question

1. Install portia on mac.https://github.com/scrapinghub/portia
Gitcone for later usedocker build -t portia .
At last, a mistake broke out.

E: Failed to fetch http://archive.ubuntu.com/ubuntu/pool/main/p/python3-defaults/python3-dev_3.4.0-0ubuntu2_amd64.deb  Connection failed [IP:  91.189.91.24 80]
 
 E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?
 Command failed (exitcode: 100), exiting  ...

Is it because ubuntu’s source needs to be changed?

This is because the download from ubuntu official source failed during the build.

  • You can try it several times, maybe you will succeed when the network is good.

  • Or change ubuntu’s source to a domestic source: for example163Yes. Note that this requires modifying the command in Dockerfile.

However, it is still recommended to download directly.Docker mirror：
docker pull scrapinghub/portia-on-dash
