There’s a problem with double quotes if you just copy paste the link. Delete and retype the quotes

I’m sure I’m an idiot, but what exactly am I supposed to type on Step #5? Thank you.

username@nkn-full-node-1-vm-1:~$ sudo su
root@nkn-full-node-1-vm-1:/home/username# cd
root@nkn-full-node-1-vm-1:~# cd nkn/nkn-commercial/services/nkn-node/
bash: cd: nkn/nkn-commercial/services/nkn-node/: No such file or directory
root@nkn-full-node-1-vm-1:~# rm -r ChainDB
rm: cannot remove ‘ChainDB’: No such file or directory
root@nkn-full-node-1-vm-1:~# cd username@nkn-full-node-1-vm-1
bash: cd: username@nkn-full-node-1-vm-1: No such file or directory

We no longer provide ChainDB after we introduced light sync in v2.1.7 (NKN MainNet v2.1.7 Release). Light sync takes much less storage space than ChainDB. Here is the quote about how to enable light sync:

How to enable fast sync and light sync

Please note that fast sync and light sync can only be enabled when node has NO local ChainDB directory (i.e. a fresh sync). You need to remove the ChainDB directory and let node do a fresh sync if you want to enable them.

There are two ways to enable fast sync and light sync:

  • Add --sync fast argument when starting nknd to enable fast sync, or add --sync light argument when starting nknd to enable light sync.

  • Add "SyncMode": "fast" to config.json to enable fast sync, or add "SyncMode": "light" to config.json to enable light sync.

You should only choose one sync mode, not both.

If you want to try light sync, you should change config from fast to light, stop nknd, remove ChainDB directory, and start nknd again

The program closes after a certain period of time during synchronization. I am using a restarter. Is there a different solution?
