Re: testing, upgrade of openssl libssl1.1 ( 1.1.0f-3 => 1.1.0f-4 )

[Michael Grant <mgrant@grant.org>]

I upgraded openssl today in my server running testing.  It installed
version 1.1.0f-5.  To my surprise, my mac clients can no longer send
and receive email!

How do I roll back to the previous version of openssl?

"apt-cache showpkg openssl" only shows version 1.1.0f-5.

apt install openssl=1.1.0f-3

E: Version '1.1.0f-3' for 'openssl' was not found

I gather I need to add something to my sources.list to get at the
older versions.
