@ytjoe perhaps try reinstalling Go, and before you do, clear out the old one. It looks to me like you have old and a new files from a Go upgrade. rm -rf /usr/local/go might help before you install again.

In fact, https://go.dev/doc/install even recommends deleting this directory if installing from a tarball download.

You could also try installing from an OS distro package instead to have this managed for you. I personally use https://snapcraft.io/go mostly to keep it updated and compatible.

Yes, that's the problem. I solved it through this method. Thank you
