brew install fails on mismatched SHA hash

[AllanLeanderRostockHansen]

Tried installing from brew but get this error (copy-pasted from my terminal):

I am not having this issue. I just downloaded the file, and it matches the SHA256:

Having the same issue just now:

rm Users/barnabas/Library/Caches/Homebrew/downloads/dcd8642740025541c389466fd4d65f20a4b31e1b178eb11971d2ebdd2747b345--killport-aarch64-apple-darwin.tar.gz

Then try to install again. Hopefully it will fix the issue.

No luck, see below:

Same here, running rm ... then rerunning brew install killport always results in SHA256 mismatch

[jkfran]

I am completely speechless. I am getting this new sha256sum right now:

How did the sha256sum change? A few hours ago, when I downloaded the file: https://github.com/jkfran/killport/issues/5#issuecomment-1521619774

I am the creator of this tool. I also used this architecture and installed it using Homebrew without this issue. I didn't release any version lately. You can check the releases which are built on GitHub and pull from there: https://github.com/jkfran/killport/releases

Is there a logical explanation for this?

[jkfran]

Could it be related to this?

[jkfran]

I keep finding reports on the internet about people having similar issues on GitHub: https://security.stackexchange.com/questions/240204/how-can-the-authenticity-of-releases-on-github-and-gitlab-be-ensured-can-their

I updated the formula. So:

brew update
brew install killport

I think it should now work. I will find a better solution, any suggestion is welcome.

[timsco]

That fixed the issue for me. Thank you @jkfran.

[speckz]

brew update now fixes the issue. However, it did not work in the past.

[jkfran]

Thank you, everyone, for using this tool. I will close this issue for now. Any contribution is welcome!
