Bug reference: 18180

PostgreSQL version: 16.0
Operating system: CentOS 7
Description:

attempting to install on CentOS 7 and receiving the following error -

#7 272.0
https://download.postgresql.org/pub/repos/yum/common/redhat/rhel-7-aarch64/repodata/repomd.xml:
[Errno -1] repomd.xml signature could not be verified for pgdg-common
#7 272.0 Trying other mirror.
#7 272.0
#7 272.0
#7 272.0 One of the configured repositories failed (PostgreSQL common RPMs
for RHEL / CentOS 7 - aarch64),
#7 272.0 and yum doesn't have enough cached data to continue. At this point
the only
#7 272.0 safe thing yum can do is fail. There are a few ways to work "fix"
this:
#7 272.0
#7 272.0 1. Contact the upstream for the repository and get them to fix
the problem.
#7 272.0
#7 272.0 2. Reconfigure the baseurl/etc. for the repository, to point
to a working
#7 272.0 upstream. This is most often useful if you are using a
newer
#7 272.0 distribution release than is supported by the repository
(and the
#7 272.0 packages for the previous distribution release still
work).
#7 272.0
#7 272.0 3. Run the command with the repository temporarily disabled
#7 272.0 yum --disablerepo=pgdg-common ...
#7 272.0
#7 272.0 4. Disable the repository permanently, so yum won't use it by
default. Yum
#7 272.0 will then just ignore the repository until you permanently
enable it
#7 272.0 again or use --enablerepo for temporary usage:
#7 272.0
#7 272.0 yum-config-manager --disable pgdg-common
#7 272.0 or
#7 272.0 subscription-manager repos --disable=pgdg-common
#7 272.0
#7 272.0 5. Configure the failing repository to be skipped, if it is
unavailable.
#7 272.0 Note that yum will try to contact the repo. when it runs
most commands,
#7 272.0 so will have to try and fail each time (and thus. yum will
be be much
#7 272.0 slower). If it is a very temporary problem though, this is
often a nice
#7 272.0 compromise:
#7 272.0
#7 272.0 yum-config-manager --save
--setopt=pgdg-common.skip_if_unavailable=true
#7 272.0
#7 272.0 failure: repodata/repomd.xml from pgdg-common: [Errno 256] No more
mirrors to try.
#7 272.0
https://download.postgresql.org/pub/repos/yum/common/redhat/rhel-7-aarch64/repodata/repomd.xml:
[Errno -1] repomd.xml signature could not be verified for pgdg-common

I have seen reports in some mail lists that this was fixed at some point,
but it is not working currently.
I have tried other PG installs/versions all throw the same error.

Thank you.
