Issues with installation

[nullptr-deref]

I've tried to install yagostatus using go install and AUR.

When trying to run go install github.com/burik666/yagostatus (go get isn't supported outside of go modules nowadays, whatever it means) I get the following message:

widgets/http.go:17:2: missing go.sum entry for module providing package golang.org/x/net/websocket (imported by github.com/burik666/yagostatus/widgets); to add:
	go get github.com/burik666/yagostatus/widgets
ygs/utils.go:11:2: missing go.sum entry for module providing package gopkg.in/yaml.v2 (imported by github.com/burik666/yagostatus/internal/pkg/config); to add:
	go get github.com/burik666/yagostatus/internal/pkg/config

Before that I've tried to install it as an AUR package, but it doesn't work either. It halts because of issue in PKGBUILD (usage of go get). I've tried to fix it but had no success.
