terminal not fully functional

I was getting the warning “WARNING: terminal is not fully functional – (press RETURN)” or in other cases “E558: Terminal entry not found in terminfo“. $TERM was xterm in gnome-terminal, while it was dumb in terminator for my user account and unknown in terminator for the root account.

In the end, adding the line export TERM=xterm to ~/.bashrc and /root/.bashrc seems to have fixed the problem…
