If you’re using tmux or screen as a wrapper for your terminal sessions (such as when using the Text Triumvirate), chances are that you are presented with the following error when you invoke a command that uses 256 color mode (such as multitail or htop):

Error opening terminal: screen-256color.

cd /usr/share/terminfo/
cp x/xterm-256color s/screen-256color
