VS Studio Code + SSH

  • Exit completely out of VSCode so that no VSCode processes are running. Force quit if you have to.
  • ssh to the remote machine(s) and delete the ~/.vscode-server directory with rm -Rf ~/.vscode-server/
  • If you get any “cannot remove [file]: Device or resource busy” errors then look for stuck processes:
  • lsof | grep $HOME/.vscode-server | awk ‘{ print $2 }’ | sort -u
  • … then kill those processes, then trying removing the directory again.
  • Restart VSCode.
