I installed Armory 0.96 (armory_0.96-gcc5.4_amd64.deb) on Ubuntu 16.04. It worked for me a couple of times but now it seems to get stuck on the scan part.

After I close Armory I cannot start it again. The log shows something like

Armory looks looks very good, looks like a lot of hard work went into creating it, so I am a bit surprised at this result. It looks like there are still major issues with it.

Should I switch to other OS? MS Windows? It does not look like this runs reliably on Ubuntu.

On first start - when scan seems to hang - logs are as follows

  • The logged error Socket already in use seems to indicate that there is already an instance of Armory running - or another application is perhaps using port 8223? – venzen Jun 21 '17 at 4:24
  • Don't think that is it. It is just user interface stuff github.com/etotheipi/BitcoinArmory/blob/master/… – onknows Jun 21 '17 at 4:35
  • At the cmd line, try netstat -al | grep 8223. If anything shows up then there is an app using that port. Also: ps -ef | grep -i armor (or whatever the Armory process is called), and try to see if bitcoind is perhaps running in the background. Seems like when you previously exited Armory, its process was not killed... – venzen Jun 21 '17 at 4:39
  • I removed armory and .armory directory and installed again, now it is working again. I keep the blockchain in separate directory / NFS share so this was a good enough solution for now. – onknows Jun 21 '17 at 5:21

    If you're using an NFS for blockchain storage this implies you're getting intermittent read/write locks that can cause Armory to hang and not properly terminate via user shutdown. Recommend you run bitcoind with local storage for datadir. – venzen Jun 21 '17 at 5:26

This error means that the background database process, ArmoryDB, is still running. Just use sudo killall -9 ArmoryDB to kill all instances of this process and start Armory again. It's fine to use -9 as ArmoryDB is good enough to handle a SIGKILL signal; I have done this many times myself.
