error: failed to compile ink-node v0.43.2, intermediate artifacts can be found at /tmp/cargo-installUPzGqE.
To reuse those artifacts with a future compilation, set the environment variable CARGO_TARGET_DIR to that path.

After fixing the above by installing protobuf this person got another error:

Getting the same error. Installed the protobuf-compiler, then it shows the same error.

[Daanvdplas]

Install the pop cli and it handles the ink-node for you:

cargo install --git https://github.com/r0gue-io/pop-cli.git --branch  v6.0.0-alpha.1 --no-default-features --locked -F polkavm-contracts,chain,telemetry

Or go to the release page and download it for your respective machine.

A new release will happen next week and we will make sure this doesn't happen again

Thank you, it worked for me.
