I might have accidentaly purged some critical files, causing my Kubuntu 14.04 to not boot past the startup logo.
By entering the recovery mode from a LiveUSB, and running sudo apt-get install -f, I am told that there are some unmet dependencies. So I am guessing those are the files that I purged.
Is there a way of installing all crucial files in recovery mode to get Kubuntu to run smoothly again?
Try this:
Boot from liveUSB.
Open a terminal.
Determine your HDD system partition.
exec sudo -i
fdisk -l
Mount your HDD system partition. X is the drive letter. Y is the partition number. Substitute the correct partition like sda1, sdb5, etc. continue running:
mount /dev/sdXY /mnt
Example: mount /dev/sda5 /mnt
If you have a separate boot partition, mount your boot partition:
mount /dev/sdXY /mnt/boot
Example: mount /dev/sdb6 /mnt/boot
Mount the critical virtual filesystems:
for i in /dev /dev/pts /proc /sys /run; do mount -B $i /mnt$i; done
Chroot into your HDD system device:
chroot /mnt
Now reinstall kubuntu:
apt-get update
apt-get install --reinstall kubuntu-desktop
apt-get install -f
apt-get dist-upgrade
exit
And reboot
for i in /dev /dev/pts /proc /sys /run; do mount -B $i /mnt$i; done part. It gives me this error: mount: mount point /mnt/dev does not exist mount: mount point /mnt/dev/pts does not exist mount: mount point /mnt/proc does not exist mount: mount point /mnt/sys does not exist mount: mount point /mnt/run does not exist This is usually where all other methods I have tried failed, too. I dont know how to fix this.

fdisk -l, I get this warning about the SSD that my system is on: WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util fdisk doesn't support GPT. Use GNU Parted.

cp -L /etc/resolv.conf /mnt/etc/resolv.conf. Now when I try and run apt-get install --reinstall kubuntu-desktop, I get a list of packages with unmet dependencies (about 100 of them)?? And the message E: Unable to correct problems, you have held broken packages. Any suggestions how to fix this?
