Introduction
This guide is specifically designed for beginners who are facing the Homebrew installation error related to network issues, particularly the “error: RPC failed; curl 92 HTTP/2 stream 5 was not closed cleanly: CANCEL (err 8)” message. Follow these steps to resolve this issue.
Step-by-Step Solutions
Check Network Connection
Ensure your internet connection is stable. If unstable, take steps to stabilize your connection.
If using a VPN, try disconnecting it to see if access to GitHub improves.
Change Git’s HTTP Transport
To potentially bypass the issue, switch Git’s HTTP transport to HTTP/1.1:
git config –global http.version HTTP/1.1
Extend Git Timeout Settings
Increase timeout settings to accommodate slower connections:
git config –global http.postBuffer 524288000
git config –global http.lowSpeedLimit 0
git config –global http.lowSpeedTime 999999
Retry Installing Homebrew
Run the Homebrew installation script again:
/bin/bash -c “$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)”
Resetting Changes
If you need to revert the changes made to Git settings, use the following commands to return to default behaviors:
git config –global –unset http.postBuffer
git config –global –unset http.lowSpeedLimit
git config –global –unset http.lowSpeedTime
