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: sonic-net#12523
…nic-net#13097) 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 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
…net#13198) Change to use the sources.list from the file generated from the j2 template
…4557) Why I did it Optimize the version control for Debian packages. Fix sonic-slave-buster/sources.list.amd64 not found display issue, need to generate the file before running the shell command to evaluate the sonic image tag. When using the snapshot mirror, it is not necessary to update the version file based on the base image. It will reduce the version dependency issue, when an image is not run when freezing the version. How I did it Not to update the version file when snapshot mirror enabled. How to verify it
