LND only supports bitcoind 0.18

The bitcoin repo uses the master branch, which is ahead of the latest release (0.18.1) Currently it's ahead in a way that makes the LND client shutdown.

This is how I fixed it for now:

./sv repos rm bitcoin
cd _repos
git clone --depth=1 --branch=0.18 --recursive https://github.com/bitcoin/bitcoin.git
./sv create [recipe] [name] -f
./sv enter [name]
./dc build
./dc up

For more info on LND only supporting 0.18, see this issue (I got the exact same error):

You steps to pin-point bitcoin repo are correct. You could also simply cd _repos/bitcoin && git checkout 0.18 without cloning it again. Simverse uses whatever you have present under _repos.

It looks like the issue has been present for quite some time and my simverse test suite was passing regardless. So it is not triggered every time.

In general I would like to find a patch or a workaround to allow simverse to use master versions of each project. This way we find regressions early.

Can you provide some steps how to trigger this issue? I would look into it.

You can trigger it like this.

  • Obviously have the latest updated repos
  • Create a recipe with a LND node and a bitcoind node
  • Create a simverse, enter and build,
  • during ./dc up you will see the following error from your LND node: Unable to create chain control: unable to retrieve best block
  • Also, ./dc ps yields an unhealthy LND node, although that might take a minute, because that might only happen after LND shuts itself down.

With regards to git checkout, I tried to checkout first, but git couldn't find the branch.
git branch -r yielded only the master branch.
Maybe because the repo was shallow? I didn't try unshallow.
