This sounds like the private SSL key you have configured is not the
private key for the public key you have configured - they do not match.

You have configured the postgres v12 server to use a directory where
there are data from a postgres v13 server. Evidently that can not work...

Can someone please help me with this?

You haven't given others enough information to help you. Present to the
fullest extent possible your current environment and the commands you are
running. Showing that psql itself works on both running clusters would be
a good start. Show inputs, not just outputs those inputs creates.

Hello,

As per error it seems you have initiated source data with PG13 binaries. 

Could you please connect to both source and target psql and share out of select versions();

Also share pg_upgrade complete command which you are using.

Actually I was using the below command to check the compatibility, it
worked without any issue with 12.6 but it is not working with 1version 2.14
time /usr/lib/postgresql/13/bin/pg_upgrade --old-bindir
/usr/lib/postgresql/12/bin --new-bindir /usr/lib/postgresql/13/bin
--old-datadir /usr/pgdata/pg_data --new-datadir /usr/pgdata/pg_data2 --link
--check

I have used a different directory for postgres13 from postgres 12.

The issue is not that they are the same directory it is:

12.14-1.pgdg18.04+1)

Check the value that is the PG_VERSION file in each data directory. It
should be 12 in /usr/pgdata/pg_data and 13 in /usr/pgdata/pg_data2.

The question asked was:

"Check the value that is the PG_VERSION file in each data directory. It
should be 12 in /usr/pgdata/pg_data and 13 in /usr/pgdata/pg_data2."

So indicate which directory path has which PG_VERSION value.

While you are at it do:

/usr/lib/postgresql/13/bin/pg_upgrade -V

and post the version returned.

Just in case I'm _not_ misreading this... are you saying you already ran
this command once with postgres v12.6?

If so, since you've used --link the original folder will no longer be
version12 data.

No, I'm an idiot. Ignore me, I missed "--check".
