Can't start node of a fork on Ubuntu 20.04

Thomas_hunter · October 20, 2021, 10:52pm

I’m running chia forks in VMs on Ubuntu. On this VM I have 3 forks: flax, tad and hddcoin. They’ve all been installed as per chia install wiki instructions and they all worked just fine. Basically so far the same behavior as with the original chia.

But after last reboot the node of either of them would not start and they all seem to have the same problem.

when I run:
cd /home/thomas/flax-blockchain && . ./activate && cd flax-blockchain-gui && npm run electron &
or
cd /home/thomas/tad-blockchain && . ./activate && cd tad-blockchain-gui && npm run electron &
or
cd /home/thomas/hddcoin-blockchain && . ./activate && cd hddcoin-blockchain-gui && npm run electron &

I get:
for flax

What did break in this VM that all of those are broken and how can I fix it? I could just ditch the whole machine and install the forks again do wait for the sync but I would rather fix the problem instead.

Hi, the latest version of Machinaris (a WebUI) supports farming these forks: N-Chain, Chives, HDDCoin, and Flora. Silicoin and other forks are coming soon. Check it out at: https://www.machinaris.app Hope this helps!

I figured it out now. It was 1 character in the config file. One space " " character.

Before “plots_refresh_parameter:” there can be only 2 spaces, I had 3 Not sure why this config is so sensitive over this. I had the same mistake in every config of all those forks. It happened as I was copying over the plot directories paths just above that line.
