Package udev is not configured yet

You have an error in udev post-installation script

addgroup: The group `input' already exists and is not a system group. Exiting.
dpkg: error processing package udev (--configure):
subprocess installed post-installation script returned error exit status 1

The other packages are just waiting for udev to complete

 initramfs-tools-core depends on udev; however:
  Package udev is not configured yet.

  1. So just make installation skip that script using

    sudo mv /var/lib/dpkg/info/udev.postinst /var/lib/dpkg/info/udev.postinst.backup
    
  2. then command below to continue previous installation.

    sudo apt-get install -f
    

It should be fine, just non robust scripts that don't expect some rare situations. Copy back that script after you finish.

sudo mv /var/lib/dpkg/info/udev.postinst.backup /var/lib/dpkg/info/udev.postinst
