Summary:

- Exact error message and exit code
  - ERROR: failed to build: failed to solve: process "/bin/sh -c yum -y update &&     yum -y install bash curl coreutils diffutils grep openssl sed make tar gcc &&     yum clean all" did not complete successfully: exit code: 1
  - Also present in logs:
    - Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra=container error was
    - 14: curl#6 - "Could not resolve host: mirrorlist.centos.org; Unknown error"
    - Cannot find a valid baseurl for repo: base/7/x86_64

- Failing command/step
  - RUN yum -y update &&     yum -y install bash curl coreutils diffutils grep openssl sed make tar gcc &&     yum clean all

- Missing packages or files mentioned
  - The failure is due to unreachable CentOS 7 repositories:
    - Could not resolve host: mirrorlist.centos.org
    - Cannot find a valid baseurl for repo: base/7/x86_64

- Version mismatch info
  - Base image used: centos:7
  - The error indicates CentOS 7 repos are inaccessible/unresolvable (baseurl for base/7/x86_64 cannot be found), which points to repository availability/dns issues rather than a specific package version mismatch.

- Exact error message and exit code
  - curl: (77) error setting certificate verify locations:
    CAfile: /etc/ssl/certs/ca-certificates.crt
    CApath: /etc/ssl/certs
  - make: *** [Makefile:69: /app/build/stamp-dehydrated-2-05eda91a2fbaed1e13c733230238fc68475c535e] Error 77
  - Failing step exit for the whole RUN: 2
    - The container reports: ERROR: process "/bin/sh -c make all" did not complete successfully: exit code: 2

- Failing command/step
  - Failing step: builder 5/5 RUN make all
  - Inside this step, the curl command that downloads dehydrated failed:
    curl -sSLo /app/build/bin/dehydrated "https://raw.githubusercontent.com/lukas2511/dehydrated/05eda91a2fbaed1e13c733230238fc68475c535e/dehydrated"
  - Result: curl returned exit code 77, causing make to fail with Error 77

- Missing packages or files mentioned
  - Caused by missing CA certificates, since CAfile points to /etc/ssl/certs/ca-certificates.crt
  - Likely missing package: ca-certificates (not installed in the apt-get install step)

- Version mismatch/info
  - Base image used: ubuntu:20.04
  - Notable warning: FromAsCasing: 'as' and 'FROM' keywords' casing do not match (line 2) in the Dockerfile
  - libc6 was upgraded during apt-get install (unpacked/set up libc6:amd64 (2.31-0ubuntu9.18) after replacing 2.31-0ubuntu9.17)
