If this is a new error: Check whether OpenSSL was updated in your OS (1.0 -> 1.1), if so, you probably have to reinstall Borg.

If you are a new user: what does openssl version say?

[ThomasWaldmann]

@smaty1 your centos6 is rather old, can't you at least go to a current 6.x version?

centos 6.3 seems to have openssl 1.0.0.
centos 6.8 has openssl 1.0.1e (in "updates" directory on mirror).

citing openssl project: "Support for version 1.0.1 will cease on 2016-12-31. No further releases of 1.0.1 will be made after that date. Security fixes only will be applied to 1.0.1 until then."

I am closing this. Likely it is just the openssl on that system that is broken (or at least not compatible with the binary).

In any case, it is way too old and not supported any more anyway.

I've frequently run borg tests (borg installed from source) on centos 6 and it worked.

Quite a while ago, I even tried to create the binaries on centos 6 (for lower glibc requirements), but the binaries were strangely slow (and we could not find out why), so I am creating the binaries now on wheezy.
