Description of issue

I am installing libssh2.

First, brew install libssh2 returned error message:
Error: libssh2: Failed to download resource "libssh2.rb" Download failed: https://raw.githubusercontent.com/Homebrew/homebrew-core/0d27f082f92021422f36a291d3795c8e59ea7eda/Formula/lib/libssh2.rb

Then, I configured libssh2 locally, the files are configured to /usr/local/lib/. However, brew info libssh2 returned message:
==> libssh2: stable 1.11.1, HEAD C library implementing the SSH2 protocol https://libssh2.org/ Not installed From: https://github.com/Homebrew/homebrew-core/blob/HEAD/Formula/lib/libssh2.rb License: BSD-3-Clause ==> Dependencies Required: openssl@3 ✔ ==> Options --HEAD Install HEAD version ==> Analytics install: 89,366 (30 days), 163,824 (90 days), 551,599 (365 days) install-on-request: 11,827 (30 days), 14,175 (90 days), 59,860 (365 days) build-error: 31 (30 days)

Lastly, I tried to fetch libssh2 first and then install it:
brew fetch --debug --verbose libssh2, this command successfully downloaded libssh2.tar.gz file.
brew install libssh2 still failed and returned the same error message.

Appreciate any suggestions.

[SMillerDev]

Can you give the full output of the command?

[ZhongRuoyu]

You need to diagnose your connection to raw.githubusercontent.com (i.e., make sure curl https://raw.githubusercontent.com/Homebrew/homebrew-core/04269cffc62f2e5cbdebf1a20a4e97b7c4e71132/Formula/lib/libssh2.rb works). It's possible that you can connect to github.com but not raw.githubusercontent.com.

[lijierr]

Yes, curl works but not between curl and https://raw.githubusercontent.com/Homebrew/homebrew-core/04269cffc62f2e5cbdebf1a20a4e97b7c4e71132/Formula/lib/libssh2.rb.

[gromgit]

Works for me, and since curl failed after just 21ms, it suggests there's a firewall or some other network device between you and that site that's actively dropping your connections.

One other thing to check: What's the output of dig raw.githubusercontent.com?

[lijierr]

Output of dig raw.githubusercontent.com:

$ dig raw.githubusercontent.com

[lijierr]

Add the correct ip of raw.githubusercontent.com to hosts file will solve this.

My added line is: 199.232.68.133 raw.githubusercontent.com

Will close this thread.

[gromgit]

Instead of adding a fixed IP mapping, which may change at any time, why not remove that entry from the DNS server on 192.168.1.1 and let it resolve normally?

[lijierr]

There are two entries of DNS server on this machine, they are not removable. I have attached a image below.

[gromgit]

I'm referring to the DNS server at 192.168.1.1 (likely your Internet gateway), which is telling you that raw.githubusercontent.com is at IP 0.0.0.0. That's wrong in every possible way, and should be corrected at the gateway, rather than having to override it on your own machine.
