cannot make directory '/run/screen' permission denied
The directory /var/run/screen/ is the socket directory for screen.
Fortunately, screen reads a environment variable SCREENDIR to get an alternative socket directory.
So to work around it, you can create a directory, such as ~/.screen:
mkdir ~/.screen && chmod 700 ~/.screen
and export the SCREENDIR to point to that directory:
export SCREENDIR=$HOME/.screen
You can also put this line into you ~/.bashrc so that it will also take effect afterwards.
