If you are facing some unmet dependencies like that and the suggested “apt –fix-broken install” doesn’t work, then maybe this suggestion will help:
Reading package lists… Done
Building dependency tree… Done
Reading state information… Done
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
ubuntu-desktop : Depends: libu2f-udev but it is not going to be installed
ubuntu-desktop-minimal : Depends: libu2f-udev but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
You should manually install the missing package, normally you will find it inside /var/cache/apt/archives otherwise you need to download it manually from Internet. In my case:
$ sudo dpkg -i --force-overwrite /var/cache/apt/archives/libu2f-udev_1.1.10-3build1_all.deb
Selecting previously unselected package libu2f-udev.
(Reading database … 332193 files and directories currently installed.)
Preparing to unpack …/libu2f-udev_1.1.10-3build1_all.deb …
Unpacking libu2f-udev (1.1.10-3build1) over (1.1.10-3build1) …
Setting up libu2f-udev (1.1.10-3build1) …
Then finally a simple apt-get install -f finished the installation:
$ sudo apt-get install -f
