go: <http://github.com/k3s-io/k3s/cmd/k3s@v1.26.1+k3s1|github.com/k3s-io/k3s/cmd/k3s@v1.26.1+k3s1> (in <http://github.com/k3s-io/k3s@v1.26.2-0.20230119155632-f10af367c3c9|github.com/k3s-io/k3s@v1.26.2-0.20230119155632-f10af367c3c9>):
        The go.mod file for the module providing named packages contains one or
        more replace directives. It must not contain directives that would cause
        it to be interpreted differently than if it were the main module.

You can download the binary from the releases page in github

for some checks and test I wan to build the binary myself, is that not possible w/o docker ?

Not via the official documented method. Dapper appears to be wrapper around Docker which is used in the makefile

ok thank you @agreeable-oil-87482
