Why I did it
Change the mirror config file
Use the files/build/versions/default/versions-mirror only when reproducible build enabled.
The config in files/build/versions is only for reproducible build, while snapshot mirror feature does not have the dependency on the reproducible build.
How I did it
Skip the mirror config in files/build/versions/default/versions-mirror if reproducible build not enabled.
How to verify it
Why I did it
[Build] Support Debian snapshot mirror to improve build stability
It is to enhance the reproducible build, supports the Debian snapshot mirror. It guarantees all the docker images using the same Debian mirror snapshot and fixes the temporary build failure which is caused by remote Debain mirror indexes changed during the build. It is also to fix the version conflict issue caused by no fixed versions of some of the Debian packages.
How I did it
Add a new feature to support the Debian snapshot mirror.
How to verify it
Why I did it
Unify the Debian mirror sources
Make easy to upgrade to the next Debian release, not source url code change required.
Support to customize the Debian mirror sources during the build
Relative issue: #12523
