Hi, I have the follwing problem, running on Fedora 21, with docker-io-1.5.0-2.fc21.x86_64: I have this Dockerfile: cat Dockerfile FROM fedora MAINTAINER tester RUN yum -y update && yum clean all RUN yum -y install httpd When I am running docker build -t test . I get: Sending build context to Docker daemon 3.072 kB Sending build context to Docker daemon Step 0 : FROM fedora ---> 834629358fe2 Step 1 : MAINTAINER tester ---> Using cache ---> 16e9f95d5ab0 Step 2 : RUN yum -y update && yum clean all ---> Running in 88b98222885a One of the configured repositories failed (Fedora 21 - x86_64), and yum doesn't have enough cached data to continue. At this point the only safe thing yum can do is fail. There are a few ways to work "fix" this: 1. Contact the upstream for the repository and get them to fix the problem. 2. Reconfigure the baseurl/etc. for the repository, to point to a working upstream. This is most often useful if you are using a newer distribution release than is supported by the repository (and the packages for the previous distribution release still work). 3. Disable the repository, so yum won't use it by default. Yum will then just ignore the repository until you permanently enable it again or use --enablerepo for temporary usage: yum-config-manager --disable fedora 4. Configure the failing repository to be skipped, if it is unavailable. Note that yum will try to contact the repo. when it runs most commands, so will have to try and fail each time (and thus. yum will be be much slower). If it is a very temporary problem though, this is often a nice compromise: yum-config-manager --save --setopt=fedora.skip_if_unavailable=true Cannot retrieve metalink for repository: fedora/21/x86_64. Please verify its path and try again INFO[0042] The command [/bin/sh -c yum -y update && yum clean all] returned a non-zero code: 1 Any ideas what can be the reason for this?
