having issues with PG12 debian packaging repository - Mailing list pgsql-hackers

Hello hackers

I am getting sporadic errors when I tried to use PG12 bionic debian repository.

Here is the error message that is result of apt-get update.

It usually succeeds when I run it again.  Is there a way to avoid this? 

Thanks
