I spent some time a few weeks ago getting the HNScan backend to run on my Linux VM. After a lot of removing, reinstalling and chatting with the kind folks in the Handshake Dev Chat I was able to get it running. Below I will list the steps that worked for me.
If you’ve already installed HSD then you should start at step 0 otherwise you should start at step 3.
Step 0: If you use HSD as a wallet back up the ~/.hsd/wallet directory and when you have completed all of the steps here copy the backup back to its original location.
Step 1: Remove the hsd and .hsd directories.
Step 2: Reboot (probably not required).
Step 3: Reinstall HSD but don’t run it (instructions here).
Step 4: Change to the hsd directory.
Step 5: Install HNScan (instructions here).
Step 6: Run HSD with the following arguments:
—index-tx=true —index-address=true —plugins=hnscan
Step 7: Give HSD about 30 minutes to sync with the blockchain. I run HSD on my Linux VM in a tmux session. When syncing every 5000 or so blocks Ubuntu would kill HSD for using too much memory. I would then run HSD again with the arguments above and it would continue the sync from the block where it got killed. I had to run HSD about ten times before it was fully synced.
Step 8: When fully synced test HNScan is running by sending the following request to HSD:
