sudo apt install gnome-tweaks не работает из-за libc6

Я пытаюсь установить gnome-tweaks, но установка не выполняется. Я запускаю в терминале следующую команду:

sudo apt install gnome-tweaks

Затем я получаю следующую ошибку:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 gnome-tweaks : Depends: gir1.2-handy-0.0 but it is not going to be installed
                Depends: gnome-shell-extension-prefs but it is not going to be installed
 libc6-dbg : Depends: libc6 (= 2.31-0ubuntu9.1) but 2.31-0ubuntu9 is to be installed
 libc6-dev : Depends: libc6 (= 2.31-0ubuntu9.1) but 2.31-0ubuntu9 is to be installed
 libc6-i386 : Depends: libc6 (= 2.31-0ubuntu9.1) but 2.31-0ubuntu9 is to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

После запуска apt --fix-broken install, в консоли отображается та же ошибка:
