One more thing here. I see that this shared library is part of ncurses and, specifically, ncurses5. Fedora 25 includes ncurses6. I see that Veeam is meant to be supported on Fedora 23-25 (I believe ncurses5 is available on F23 but not F24/F25). I see that I have the .fc23 veeam install present:
veeam.x86_64 18.104.22.1684-1.fc23 @veeam
I've tried a 'dnf update veeam' to see if there's an updated version of veeam (.fc25?), but this never actually does anything. Seems like I need a new build of veeam for FC25 (I hesitate to try to get both ncurses5 and ncurses6 installed - and working correctly - in parallel on my F25 target).
