RHEL/CentOS 6 Support

[JonMikelV]

I’m not very familiar with CentOS and I realize this is CentOS 7 and you’re asking about CentOS 6 but perhaps this can give you some ideas?

How do I install on CentOS 7?

OK – (for others in a similar bind) I solved the problem by first installing EPEL (http://mirror.cs.princeton.edu/pub/mirrors/fedora-epel/7/x86_64/e/) and then I was able to explicitly run yum install libappindicator Once I did that, I was then able to install Duplicati by first downloading it and then running yum --nogpgcheck localinstall duplicati-2.0.2.10-2.0.2.10_canary_20171011.noarch.rpm
