What version of Go are you using? How did you install it?

[alec-djinn]

I am using GO 1.11.4 installed using Linux binaries from here https://golang.org/dl/
Unpacked the bin in /usr/local and added the path in the .bashrc file.
export PATH=$PATH:/usr/local/go/bin exactly as specified in the Installation Instruction https://golang.org/doc/install

After that, I have also included the following lines in the .bashrc

export GOPATH=~/gocode
export PATH=$PATH:$GOPATH/bin

Solved by installing libc6-dev
