This seems to have a private key.

do you have the correct `signetchallenge` in `bitcoin.conf`?

What are you trying to accomplish? If you want to start a brand new signet chain you need to add `signetchallenge=...` in `bitcoin.conf` with a BIP325 challenge: https://github.com/bitcoin/bips/blob/master/bip-0325.mediawiki#specification

You will not be able to generate blocks on the default signet chain because you do not have the correct private key. You can try one of the other methods listed here: https://github.com/bitcoin/bitcoin/blob/master/contrib/signet/README.md

📝 ryanofsky reopened a pull request: "ci: build multiprocess on most jobs"
(https://github.com/bitcoin/bitcoin/pull/30975)
This builds most of the CI jobs with multiprocess enabled.

Two jobs run the functional test suite, one with depends and one with the regular build.

The Windows job does not use multiprocess since that's not supported yet.

The previous version of this PR changed the `depends` system to build libmultiprocess by default as one of the final steps for #31098 - but based discussion here and on IRC it was decided it's too early to ship it.

(https://github.com/bitcoin/bitcoin/issues/31799)
### Please describe the feature you'd like to see added.

Post-quantum cryptocurrencies are an emerging field that aims to secure transactions and blockchains against attacks by quantum computers. The latter, thanks to their exponential computing power, could break the classic cryptographic systems used today (such as RSA, ECC and ECDSA) and compromise the security of blockchains.

Why post-quantum cryptos?

Blockchains mainly use two cryptographic mechanisms vulnerable to quantum computers:

This is because we'd now perform the checkpoints check twice, but it'd fail the second time since a checkpoint with a higher height would already be in the index. Instead of introducing more complexity there i rebased on top of #31649.

Closing, as the troubleshooting tips in this PR are too narrow. I ran the same commands on MacOS and got an entirely different set of lcov errors.

FWIW, I agree with you and want this to always be external. I personally find it more convenient to work on the library in its standalone git repository, and think cmake's `find_package` mechanism is a cleaner and easier to maintain form of integration than the `add_subdirectory` trick used in this PR. So this PR intentionally does not remove any ability to use the library externally, and it makes git subtree a pure m
