exact same issue here
R80.30 --> R80.40 .. stuck at 36% Importing IPS Data ...
..indefinitely it seems. I note that sduuGo process seems to run very high CPU on one core, and gets stuck (or at least stuck for a period, then stops, then tries again) - i've read this process relates to IPS updates. The target appliance has no internet access so i wonder if that is the reason... lsof -p <sduuGo_PID> shows the below ...same list of temp files on every attempt.
