Всякий раз, когда я пытаюсь обновить, обновить и установить любое программное обеспечение на Ubuntu18.04 я получаю неудовлетворенные зависимости ошибка

Все работало нормально, но после sudo apt upgrade я получил красную иконку тире на панели уведомлений и начал сталкиваться с конфликтами с версиями python,

при попытке :

sudo apt upgrade

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 libpython3.7 : Depends: libpython3.7-stdlib (= 3.7.10-1+bionic2) but 3.7.9-1+xenial1 is installed
 libpython3.7-dev : Depends: libpython3.7-stdlib (= 3.7.10-1+bionic2) but 3.7.9-1+xenial1 is installed
 libpython3.7-stdlib : Depends: libpython3.7-minimal (= 3.7.9-1+xenial1) but 3.7.10-1+bionic2 is installed
 python3.7 : Depends: libpython3.7-stdlib (= 3.7.10-1+bionic2) but 3.7.9-1+xenial1 is installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
