I tried to upgrade my system from Ubuntu 14.04. My laptop froze for a few hours. Not even the pointer did anything. So I switched off by pressing the power button for a few seconds. This uncompleted installation is the origin of my problem. When I reboot the system, grub appears and then, the following message:

[FAILED] Failed to start Load Kernel Modules
See 'systemctl status systemd-modules-load.service' for details

Plus some other lines that end with a final:

Failed to start Load Kernel Modules

When I open a command line by pressing CTRL+ALT+F1 I'm able to enter

sudo systemctl status systemd-modules-load.service

and I get the following output.

status systemd-modules-load.service

If I repeat the systemctl command, I get sometimes other process instead of 179, for example, 183.

Just in case it's needed,

sudo ls /lib/systemd/system/systemd-modules-load.service

gives me

/lib/system/systemd-modules-load

(written in green)

journalctl

outputs a lot of data. The red lines are the following ones.

First red line.

Second and third red line.

Fourth red line.

I'll really appreciate a little help here I don't know what to do next and i've searched the web for nothing

I found exactly what I needed in a discussion in ubuntuforums.org. I'm specifically looking for the command

dpkg --configure -a

The linked article above mentions four commands that may help resolve this problem and notes that they may need to be repeated "in no specific order".

apt-get update
dpkg --configure -a
apt-get dist-upgrade
apt-get -f install
