Вот, собственно:
dpkg: dependency problems prevent configuration of linux-generic:
linux-generic depends on linux-headers-generic (= 4.4.0.141.147); however:
Version of linux-headers-generic on system is 4.4.0.139.145.
sudo apt-get dist-upgrade
Reading package lists...
Building dependency tree...
Reading state information...
You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
linux-image-generic : Depends: linux-image-4.4.0-141-generic but it is not installed
Depends: linux-image-extra-4.4.0-141-generic but it is not installed
Recommends: thermald but it is not installed
E: Unmet dependencies. Try using -f.
Основные рекомендации, которые надо выполнить при подобных проблемах, я сделал - но не помогло.
