Hi All,
I try to setup a Linux server with granular recovery based on the description from this site here:
(c)XSIBackup-DC granular recovery

The difference on my side is, that I'm using a Ubuntu Linux 20.04 instead of CentOS.
My problem is, that I get the following error message when I ty to start xsifs: xsifs: error while loading shared libraries: libcrypto.so.10: cannot open shared object file: No such file or directory

I think, I just need a symlink to an existing lib, but I'm not sure how to solve this.
Can someone help me out of this?

Thanks
Stefan
