set -ue is good.  I think every script should use it.

If you wish to ignore errors, write explicit code to do so.

For example:
  possibly bad command 
becomes:
  possibly bad command || true
or better:
  if ! possibly bad command ; then
    echo "possibly bad command failed with $?; continuing anyway" >&2
  endif
