@thinkerou Hi, there! I handled one v1.7.5 copy by myself, you can refer to it:
https://github.com/Bisstocuz/gin/commits/v1.7.6

I tested it by go get -u github.com/Bisstocuz/gin@v1.7.6 so I think it should work normally.

And at the same time, you can mark it as v1.7.6 to skip this retracting version.

If need, I can help to open a new pull request copied from #2943 to skip the merge permission limit. (#2952)

You SHOULD retract v1.7.5 in go.mod file and release new version (v1.7.6-pre).

if GOPROXY is used, the broken version will be downloads from cache until you retract it.

docker run golang:1.17

$ go env
...
GOPROXY="https://proxy.golang.org,direct"
GOSUMDB="sum.golang.org"
...
$ go get github.com/gin-gonic/gin
go: downloading github.com/gin-gonic/gin v1.7.5
.....
# github.com/gin-gonic/gin
pkg/mod/github.com/gin-gonic/gin@v1.7.5/context.go:735:13: c.engine.AppEngine undefined (type *Engine has no field or method AppEngine)
pkg/mod/github.com/gin-gonic/gin@v1.7.5/gin.go:154:3: unknown field 'UseRawPath' in struct literal of type Engine

$ GOPROXY="direct" go get github.com/gin-gonic/gin
go: downloading github.com/gin-gonic/gin v1.7.4

Go version < 1.16 ignore retract directives.

I removed a bad release from my repository but it still appears in the mirror, what should I do?
Whenever possible, the mirror aims to cache content in order to avoid breaking builds for people that depend on your package, so this bad release may still be available in the mirror even if it is not available at the origin. The same situation applies if you delete your entire repository. We suggest creating a new version and encouraging people to use that one instead.
