Error message

results.error

What it means

After running `uname -sm`, GetClientPlatform normalizes the output and requires exactly two whitespace-separated fields (kernel-name and machine). If the output splits into anything other than 2 fields, this error is returned with the raw output. It indicates the remote `uname` produced malformed or polluted output.

Solutions

1. Remove echo/banner statements from shell startup files (.bashrc/.profile) for non-interactive shells
2. Run `uname -sm` manually inside the distro and check it prints exactly two fields like "linux x86_64"
3. If uname is empty, fix the distro image or install coreutils
4. Alternatively use GetClientPlatformFromOsArchStr with a known-good string

Example fix

// before (in ~/.bashrc of the remote)
echo "Welcome to my distro"  # pollutes uname output -> 3+ fields
// after
case $- in
  *i*) echo "Welcome to my distro" ;; # only print banner in interactive shells
esac

out, _ := genconn.RunSimpleCommand(ctx, shell, genconn.CommandSpec{Cmd: "uname -sm"})
if len(strings.Fields(strings.TrimSpace(out))) != 2 {
    return fmt.Errorf("remote uname output polluted: %q", out)
}

os, arch, err := wslconn.GetClientPlatform(ctx, shell)
if err != nil && strings.Contains(err.Error(), "unexpected output from uname") {
    // check remote shell rc files for banner/echo statements
}

When it happens

Trigger: InstallWsh calls GetClientPlatform and `uname -sm` returns 0 fields (empty) or more than 2 fields (extra text such as shell banners prepended to output).

Common situations: Shell rc files echo banners/motd into non-interactive command output; empty output because uname silently failed; vendor-modified uname emitting extra fields.
