Description:

We just started seeing this repo error for pgdg-common recently when trying
to do updates.  

Importing GPG key 0x442DF0F8:

[Errno -1] repomd.xml signature could not be verified for pgdg-common
Trying other mirror.

Further experimenting showed there is a similar problem for pgdg15, pgdg14,
pgdg13, and pgdg12.
