The cause is that MATE version 1.10 will use galculator and neither mate-calc nor gcalctool which are what the old version of mate-settings-daemon looks for.
Ubuntu-MATE has already chosen to use galculator but its mate-settings-daemon has not yet updated (still on 1.8.1).
This is fixed in Git, in mate-settings- daemon 1.9.2. See the commit: https:/ /github. com/mate- desktop/ mate-settings- daemon/ commit/ 163f01a8b527c1e d801f68681fc7d8 2a54d42b1c
