How do I fix apt-get and apt-update/upgrade after my computer shut down during an installation?

Question

I was running sudo apt update ; sudo apt upgrade -y and midway through the installation my computer ran out of battery and shut down abruptly. Side note - I'm using the Windows Subsystem for Linux on Windows 10.

Now when I run sudo apt upgrade I'm getting errors that I can't figure out how to work around. Here's what I get:

~$ sudo apt upgrade -y

You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
libpam-systemd : Depends: systemd (= 229-4ubuntu21.6) but 229-4ubuntu21.4 is installed
systemd : Depends: libsystemd0 (= 229-4ubuntu21.4) but 229-4ubuntu21.6 is installed
E: Unmet dependencies. Try using -f.

So I try that and here's what I get:

~$ sudo apt upgrade -y -f

How do I fix this and get my package manager back to a healthy state?

Answer 1

I would try to first clean with

sudo apt-get clean

then try

sudo dpkg --configure -a

or/and

sudo apt upgrade --fix-missing

Answer 2

It seems that the file /var/cache/apt/archives/systemd_229-4ubuntu21.8_amd64.deb is corrupted.

While trying to install systemd, The package manager assumes that there is already a cached deb file, so just delete it and run sudo apt-get -f install again.

Answer 3

On my normal Ubuntu 18.10 that file you have missing does appear however its just a symlink as per :

ls -la /lib/systemd/system/checkroot-bootclean.service 
lrwxrwxrwx 1 root root 9 Nov  9 03:15 /lib/systemd/system/checkroot-bootclean.service -> /dev/null

so to give yourself such a file issue

sudo ln -s /dev/null /lib/systemd/system/checkroot-bootclean.service 

then reissue your

sudo apt-get -f install

This is just a hunch however that missing symlink may be part of a larger issue ... dunno until you try

Just to give some context here is my entire /lib/systemd/system/

scott@berghia /lib/systemd/system $ ls -la /lib/systemd/system/
