Package: apt-cacher-ng Version: 3.7.4-1+b2 OS: Debian GNU/Linux 12 (bookworm)
When multiple systems attempt a package installation through apt-cacher-ng, some are returned a 503 error due to what appears to be a problem with simultaneous access. It appears that apt-cacher-ng is attempting to backup the repo index file multiple times with the same name. The problem does not happen when systems install packages at different times.

In our case, the simultaneous access is caused by execution via ansible and throttling those operations is highly undesirable due to environment scale and time considerations. Is there an option to disable this backup operation altogether and simply overwrite the index file or to pull the index only once despite multiple requests?
