You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
libreoffice-base-core : Depends: ure but it is not going to be installed
libreoffice-calc : Depends: ure but it is not going to be installed
libreoffice-common : Depends: ure but it is not going to be installed
libreoffice-core : Depends: ure (>= 3.5.4~) but it is not going to be installed
libreoffice-draw : Depends: ure but it is not going to be installed
libreoffice-gnome : Depends: ure but it is not going to be installed
libreoffice-gtk : Depends: ure but it is not going to be installed
libreoffice-impress : Depends: ure but it is not going to be installed
libreoffice-math : Depends: ure but it is not going to be installed
libreoffice-writer : Depends: ure but it is not going to be installed
python-uno : Depends: ure but it is not going to be installed
synaptic : Depends: libept1.4.12 but it is not going to be installed
            Depends: libvte9 (>= 1:0.24.0) but it is not going to be installed
uno-libs3 : Depends: ure but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

Я не знаю, как это исправить, sudo apt -get -f install также не работает, и я не могу выполнить обновление с помощью терминала и диспетчера обновлений.
