checksum mismatch

[vrischmann]

Describe the bug

I'm trying out the Chat example but I'm getting a checksum mismatch:

$ go get -t ./...
go: downloading github.com/charmbracelet/bubbles v0.21.0
go: downloading github.com/atotto/clipboard v0.1.4
go: downloading github.com/charmbracelet/x/ansi v0.9.3
go: downloading golang.org/x/text v0.3.8
go: test-bubbletea imports
	github.com/charmbracelet/bubbles/textarea imports
	github.com/charmbracelet/x/ansi: github.com/charmbracelet/x/ansi@v0.9.3: verifying module: checksum mismatch
	downloaded: h1:N/UztZRAGcBZH0peJzdQkNQ/l9O2eSvAekrnQ7VdSOY=
	sum.golang.org: h1:BXt5DHS/MKF+LjuK4huWrC6NCvHtexww7dMayh6GXd0=

SECURITY ERROR
This download does NOT match the one reported by the checksum server.
The bits may have been replaced on the origin server, or an attacker may
have intercepted the download attempt.

For more information, see 'go help module-auth'.

it's working for me, maybe it was a temporary error?

ok, I just checked again and I didn't realize before that the problem only occurs when using GOPROXY=direct which I use by default. With GOPROXY=proxy.golang.org go get ./... it works fine:

FWIW, I asked about this in Discord a while ago:
https://discord.com/channels/1032368467246075914/1383198045260484658

I believe the devs accidentally pushed one or more ansi tags weirdly, resulting in checksum mismatches when using GOPROXY = direct.

I think cutting another tag without GOPRIVATE set should fix the issue.

@aymanbagabas Worth cutting another release here? I encounter it a lot too, with the solution usually being sudo rm -rf "$GOPATH/pkg".
