What did you do?

I have private modules replaced with local modules in my go.mod in the mycompany.com/...

module mycompany.com/clientname/server

go 1.14

require (
    github.com/lib/pq v1.7.0
    github.com/99designs/gqlgen v0.11.3
    github.com/vektah/gqlparser/v2 v2.0.1
    golang.org/x/oauth2 v0.0.0-20200107190931-bf48bf16ab8d
    mycompany.com/clientname/models v0.0.0-00010101000000-000000000000
    mycompany.com/common/utils v0.0.0-00010101000000-000000000000
)

replace mycompany.com/common/utils => ../../common/utils

replace mycompany.com/clientname/models => ../models

The mycompany.com is just fictional, there isn't a server on the url and I run go get -u all

What did you expect to see?

Update the valid modules in go.mod and leave the local/replaced ones

What did you see instead?

go get -u all fails with go get all: unrecognized import path "mycompany.com/common/utils": reading https://mycompany.com/common/utils?go-get=1: 404 Not Found

It finds the new versions of the github.com modules, then fails and doesn't update go.mod
