RPMs changing in the yum repository

I'm not sure where to send this message.

We synchronize a copy of the pgdgXX and the pgdg-common repositories 
using the reposync tool.

Occasionally this tools reports errors and will not download some rpms. 
An example of the errors are

pgbouncer-debuginfo-1.20.1-42P FAILED
pgbouncer-1.20.1-42PGDG.rhel7. FAILED
pgbouncer-debuginfo-1.20.1-42PGDG.rhel7.x86_64: [Errno 256] No more 
mirrors to try.
pgbouncer-1.20.1-42PGDG.rhel7.x86_64: [Errno 256] No more mirrors to try.


It seems obvious that this is some kind of network error or some general 
download issue that could be retried at a later time, however, the root 
cause of this is that these RPMs had previously been downloaded but the 
files were changed in the source repository.

If I move my existing rpms out of the way, the reposync tool happily 
downloads the rpms again with no error.

After I have downloaded the files again, I can confirm that they are 
different than the previously downloaded copy.

I can also confirm that the rpms I had were not corrupted. They matched 
the copy in our backup system. They were dated Aug 9, 2023 and were 
backed up on 2023-08-29 (we synchronize the repository on the 28 of each 
month). The rpms downloaded today are dated Oct 17, 2023 which also 
matches the date on the latest release pgbouncer-debuginfo-1.21.0-42PGDG 
and pgbouncer-1.21.0-42PGDG.

It seems like files in the repository got deleted and were rebuilt with 
the same version/release identifiers.

Looking at the rpms themselves, the previously downloaded rpm is


rpm  -qip pgbouncer-1.20.1-42PGDG.rhel7.x86_64.rpm

and the latest download is

rpm  -qip pgbouncer-1.20.1-42PGDG.rhel7.x86_64.rpm

Name        : pgbouncer

The "Build Date" is now different and it appears that the Signature has 
been removed.


This all seems to be a very uncommon workflow and is causing failures in 
the ability to synchronize the repository.
