cURL error in various homebrew installations

I'm using my (quite old) Macbook with macOS 10.10. I have been struggling to install the following programs using homebrew: ffmpeg, cairo, and sox. Whenever I run brew install ffmpeg it al runs well until eventually, I run into the following error:

==> Downloading https://download.gnome.org/sources/glib/2.64/glib-2.64.3.tar.xz

curl: (35) SSL peer handshake failed, the server most likely requires a client certificate to connect
Error: Failed to download resource "glib"
Download failed: https://download.gnome.org/sources/glib/2.64/glib-2.64.3.tar.xz

As far as I know, there is an issue with the version of cURL being used, which does not support OpenSSL, and SecureTransport is getting in the way. I saw this when running:

curl 7.43.0 (x86_64-apple-darwin14.0) libcurl/7.43.0 SecureTransport zlib/1.2.5
Protocols: dict file ftp ftps gopher http https imap imaps ldap ldaps pop3 pop3s rtsp smb smbs smtp smtps telnet tftp 
Features: AsynchDNS IPv6 Largefile GSS-API Kerberos SPNEGO NTLM NTLM_WB SSL libz UnixSockets

It seems that the cURL that is being used is the one built in with the OS, I tried switching to the homebrew one by editing my $PATH in my .bash_profile, and ran the following, finding SecureTransport again:

$ which curl
/usr/local/opt/curl/bin/curl
$ curl -V
curl 7.71.1 (x86_64-apple-darwin14.5.0) libcurl/7.71.1 SecureTransport zlib/1.2.5
Release-Date: 2020-07-01

but this was no help. I also tried brew upgrade,brew uninstall curl and then brew install curl-openssl but this homebrew installation also runs into the same curl(35) error.

How can I disable SecureTransport? Is there any other possible fix? Is it necessary for me to update my macOS to a more recent version?

secure-transport homebrew openssl curl

Use the homebrew-installed curl instead. For that set HOMEBREW_FORCE_BREWED_CURL. From man brew

If set, always use a Homebrew-installed curl(1) rather than the system version. Automatically set if the system version of curl is too old.

First of all, feel pretty bad for your situation that homebrew only supports the latest three MacOS versions (which are high-sierra, mojave and catalina at this moment), this aligns with the Apple's security patch policy as well.

Second, regarding your glib downloading issue, I just did a download myself, seems working fine now (we usually use bintray homebrew mirror to mitigate the issue like this), but I just checked the homebrew core codebase, we did not have mirror for gnome source artifacts though (hope that you won't run into such issue again) .

Third, regarding how to override the MacOS default curl, you can just do echo 'export PATH="/usr/local/opt/curl/bin:$PATH"' >> ~/.bash_profile && source ~/.bash_profile.

Here is what I have in my local before/after:

$ ls -al $(which curl)
-rwxr-xr-x  1 root  wheel  185072 May 20 04:14 /usr/bin/curl

$ curl --version

$ ls -al $(which curl)
-r-xr-xr-x  1 rchen  staff  209876 Jul  4 15:58 /usr/local/opt/curl/bin/curl

$ curl --version

Final comment is if you don't have to install the latest ffmpeg, cairo, and sox, I can probably find you the bottles for MacOS 10.10.

Hope it helps.

Run a command:

export HOMEBREW_FORCE_BREWED_CURL=1

It will set an environment variable for the current shell session to use brew curl which is newer than is installed on your system.

You can read about it on official homebrew documentation.
