make lint errors running golangci-lint during make presubmit

[George K]

Doing dry run with the steps from here and getting errors: https://github.com/google/syzkaller/blob/master/docs/contributing.md

Ran make install_prerequisites followed by make presubmit and get these errors (have not touched any files):

On ubuntu at latest Syzkaller. Any idea what I'm doing wrong?

Thank you,

Hi George,

It looks like your Go installation is broken. It fails to import
standard library packages.

What I would try is to download the latest Go distribution from:
https://go.dev/dl/
then unpack it into, say, /home/me/go
then set GOROOT=/home/me/go
and PATH=/home/me/go/bin:$PATH
