Repo mdp/qrterminal used the old path to import rsc/qr, and didn’t use module in the version v1.0.0.
This caused that github.com/rsc/qr and rsc.io/qr coexist in this repo:
https://github.com/kreuzwerker/awsu/blob/master/go.mod (Line 9 & 18)
That’s because the rsc/qr has already renamed it’s import path from "github.com/rsc/qr" to "rsc.io/qr". When you use the old path "github.com/rsc/qr" to import the rsc/qr, will reintroduces rsc/qr through the import statements "import rsc.io/qr" in the go source file of rsc/qr.

Background
Repo
mdp/qrterminal
used the old path to importrsc/qr
, and didn’t use module in the version v1.0.0. This caused thatgithub.com/rsc/qr
andrsc.io/qr
coexist in this repo: https://github.com/kreuzwerker/awsu/blob/master/go.mod (Line 9 & 18)That’s because the
rsc/qr
has already renamed it’s import path from "github.com/rsc/qr" to "rsc.io/qr". When you use the old path "github.com/rsc/qr" to import thersc/qr
, will reintroducesrsc/qr
through the import statements "import rsc.io/qr" in the go source file ofrsc/qr
.https://github.com/rsc/qr/blob/v0.1.0/qr.go#L15
"github.com/rsc/qr" and "rsc.io/qr" are the same repos. This will work in isolation, bring about potential risks and problems.
Solution
Then clean the go.mod.
