Como posso corrigir isso?
Você não pode, o mantenedor tem que fazer isso.
O Debian sid está atualmente passando pela transição gcc5 , que está causando problemas muitos problemas de desinstalabilidade como este (o libreoffice não é a única coisa no mesmo barco; a maioria do KDE tem o mesmo problema).
Você pode tentar instalar o libreoffice a partir do stretch (teste), que ainda deve funcionar no momento. Como alternativa, aguarde até a transição terminar.
