Building with go 1.21 fails at quic-go step

[plexxman]

System: Arch Linux 6.4.10-arch1-1
Package information:

• go 2:1.21.0-1 (from official repositories)
• xcaddy-bin 0.3.5-1 (from AUR)
• xcaddy 0.3.5 (binary from this repo releases)

With recent go's 1.21 update, xcaddy doesn't build a custom caddy version with modules and throws the following error related to quic-go (I assume by the logs). I tested both with AUR's package, and downloading the binary directly from this repo to be sure and both give the same error:

Reverting back to go 2:1.20.7-1 fixes the issue and xcaddy builds correctly a custom version of Caddy with modules. If you need more tests let me know.

PD.: Sorry for using pastebin but I had a weird issue while adding the log in a code block here.

This is a known issue that is being fixed by Caddy v2.7.4 today.

(Go made a last-minute breaking change to new APIs which broke quic-go moments before release. See https://github.com/quic-go/quic-go/releases/tag/v0.37.4)

Roger that, I'll stay in position then! Thanks for the quic😄 response.

I can confirm that it is fixed with Caddy 2.7.4, building perfectly with go 1.21.

Thanks! That's good. :)
