[mak-021]

Hi,

My os is windows 10 on which i have installed golang1.16 andd the version of golang on my vscode is1.13
but since I am using my laptop for work ,i have been asked to upgrade from 1.13 to 1.15
I did the following steps in terminal of vscode-ubuntu
$ sudo wget https://golang.org/dl/go1.15.5.linux-amd64.tar.gz
$ sudo tar -C /usr/local -xzf go1.15.5.linux-amd64.tar.gz
$ export PATH=$PATH:/usr/local/go/bin
$ source ~/.bashrc
$ go version

still it shows version 1.13

kindly guide
thanking in advance

I reinstalled vscode,ubuntu and wsl as the cache kept holding onto previous installations of go.
Now it correctly shows go 15 at the bottom of the vscode window.
I typed 'which-a go'
now it shows usr/local/go/bin/go
Now the issue has been resolved.Thanks again.
