Your peer sent a server certificate that was signed by some intermediate
or root CA. The chain sent was incomplete, at least one certificate is
missing. As you do not have a local copy of the (intermediate or root)
CA certificate, you cannot subsitute the missing certificate.
 unable to get local issuer certificate
should better read
 unable to get issuer certificate locally :-)

The other errors are the consequence of the first one.

The missing certificate should be available in this directory to succeed.
Make sure to create the hash link files in the directory and to understand
the implications of chroot operations.
