seal is invalid when using --mining-public-key flag

[fzeeshan]

when you run a node with mining key, it gives out the following error "Unable to import mined block: seal is invalid"

[JoshOrndorff]

This happens when you are mining with an algorithm that is not accepted by your consensus. Try adding --minining-algo md5 to your cli. Then read about that flag and others with --help.

thank you Josh, seems like the issue was actually with --mining-public-key flag. For example:
./target/release/academy-pow --chain=production.json -d data/production/alice --validator
or
./target/release/academy-pow --chain=production.json -d data/production/alice --validator --mining-algo md5
works, but if I add --mining-public-key=0xd43593c715fdd31c61141abd04a99fd6822c8558854ccde39a5684e7a56da27d it gives the following message: Unable to import mined block: seal is invalid, i will add md5 for now and remove the key flag. thanks

The --mining-public-key flag seems to work for me even with the exact format and key you suggested:

joshy@pop-os:~/ProgrammingProjects/Academy-PoW$ ./target/release/academy-pow --chain local --validator --mining-public-key=0xd43593c715fdd31c61141abd04a99fd6822c8558854ccde39a5684e7a56da27d

Can you past your exact output? And also the content of the chain spec you are using?

I am not sure what I did, I am still seeing the same error (Unable to import mined block: seal is invalid) when I try this: ./target/release/academy-pow --chain local --validator --mining-public-key=0xd43593c715fdd31c61141abd04a99fd6822c8558854ccde39a5684e7a56da27d
I wonder if if there is something on my system that's causing this issue. I believe I built it using nightly-2024-05-23. I may have to start all over again.

[JoshOrndorff]

The toolchain should be fine as long as it compiled without error. Do you know what commit of the project you built? Try pulling the latest master and trying again.

IDK how much experience you have with Substrate, but you may have existing chain data interfering. Consider the purge-chain command or running with the --tmp to get a fresh temporary data directory.

I some what found the solution, I made a copy of this repo couple weeks ago, I think it is two commits behind this one, when I use my copy it works perfectly fine. I believe something changed and caused this repo to break. I am pretty sure anyone trying it out for the first time will encounter same issues. thanks
btw here is my repo: (https://github.com/fzeeshan/Academy-PoW2)
I see there were some changed and sp-keyring = { workspace = true } was added.
