Hi, guys i have a problem...can't sync my qt wallet, it ctuck on 2097394 block...i downloaded v1.4.17 from official site, downloaded bootstrap.dat from this
https://bitcointalk.org/index.php?topic=623147.msg9772191#msg9772191 post and put it in folder where my wallet.dat is....it goes fine till wallet renamed it (bootstrap.dat.old) sync stopped on that block...I made clam.conf and add some nodes but still nothing...on client i see a have 16 active connections... "importing blocks" in lower left corner is gone and it's really annoying because i lost 5-6 hours (in last 4 days) on this...

Finally, after 10 days i was able to sync my QT wallet...in 5 years of my mining experience i have never seen .....naaaah, it takes to much of my time... never mind. Good luck to all who have this....."coin".

Very slow syncing is a known problem with the CLAM client... unfortunately no one has figured out why, yet. If your client stays open everything works fine, but if you leave things for a few days, the debug log gets filled with errors like "ORPHAN BLOCK 751" and "already have block..."
Just a warning, do NOT use Yobit for CLAM (or anything, really)
If anyone is trying to get CLAM (headless daemon) working on Ubuntu 18.10, Iv'e got a one liner for you:
curl -L https://gist.githubusercontent.com/daxxog/a2f5db9cbe5fd02770764ba183dc6504/raw/clambuntu.sh | sh
My code works around the ORPHAN BLOCK 751 bug by restarting the daemon if it finds the error in the logs.. Not the most elegant solution, but it works. This script also grabs the latest bootstrap from doog's aws. I also have a version for raspberry pi 3, which is pretty similar since the pi (raspbian) is Debian based (like Ubuntu is).
Feel free to look at the source code (bash):
