Why Does \"sudo go run main.go\" Fail on Ubuntu?

Debugging "sudo go run main.go" Execution Error on Ubuntu

Executing "sudo go run main.go" in a Ubuntu 16.04 environment often leads to the error "executable file not found in $PATH." This stems from the fact that environment variables are not preserved for the root user by default. To address this issue, follow the steps below:

Disable Environment Reset:

1. Edit the file /etc/sudoers.
2. Find the line that reads "Defaults env_reset" and change it to "Defaults !env_reset".

However, this method may not resolve the problem.

Correct Approach:

The recommended approach is to build the binary without sudo and execute the binary with sudo. Steps to do so:

1. Navigate to the directory containing main.go.
2. Build the binary using go build.
3. Execute the binary using sudo, e.g.:

sudo ./mycapt

Alternatively, you can use go install and then execute the binary using:

sudo $GOPATH/bin/mycapt

By following these steps, environment variables will be preserved and you will be able to successfully execute the Go binary with sudo permissions.
