What were you trying to do (and why)?

I was trying to update brew with brew update

What happened (include all command output)?

While trying to run brew update, the system hanged.

I then ran brew update -d to run in debug mode and noticed that it hung on the following logs:

rm -f /opt/homebrew/.git/TMP_FETCH_FAILURES

What did you expect to happen?

I expected brew to update

Getting the same issue. Running brew update just hangs (5 mins at least). Ran Brew update-reset also had a hang when Fetching /opt/homebrew/Library/Taps/homebrew/homebrew-core… but it did (after several mins resolve and proceed normally. Tested network connections between my local computer and host and am able to connect @ 1.1Gbps with no packet loss. Could still be on GitHub side but just thought I’d share my experience. Snippet of the update-reset below with the slow step bolded.

Running brew update-reset before brew update fixed this for me.

For issues with initial installs, refer to https://github.com/orgs/Homebrew/discussions/666. Initial install does take several minutes and we’re aware some networking setups (ISPs, proxies, etc.) have issues with git fetches that take that length of time (e.g. Virgin Media).

This issue is mostly about brew update being suddenly being slow on existing previously-working installs (where it should take a few seconds), which is an issue I’ve seen less today so it might be fixed.

Running into this issue as well on an initial fresh install, with no indication of how to fix.

brew update-reset does not finish successfully either:

…it just always fails.

Same issue here, but brew update-reset is hanging on homebrew-core for me too…
