upgrade from 14.04 to 16.04 fails on udisks2 - udevadm trigger is not permitted

[chomezski]

Hi All

Hoping to get some help.

I've performed an upgrade from 14.04 to 16.04 and the upgrade fails on trying to install udisks2, when I try to reboot it boots into the initramfs shell.

I'm now booting from the liveCD and following https://help.ubuntu.com/community/LiveCdRecovery I'm mounted my root partition and chroot'd to it.

kubuntu@kubuntu:~$ sudo mount /dev/sdc1 /mnt/
kubuntu@kubuntu:~$ sudo mount --bind /dev /mnt/dev/
kubuntu@kubuntu:~$ sudo mount --bind /proc /mnt/proc/
kubuntu@kubuntu:~$ sudo mount --bind /sys /mnt/sys/
kubuntu@kubuntu:~$ sudo chroot /mnt/

I run apt-get install -f I get the following:

root@kubuntu:/# apt-get install -f

I've tried:

sudo update-initramfs -u -k all

This doesn't help. I've also ended up trying to remove udisks2 and reinstall but doesnt work. I've tried reinstalling udev but get the following:

root@kubuntu:/# apt-get install --reinstall udev

Any ideas of where I can go next?

Hello and welcome to the forum, I have seen dozens of post like this with users having problems upgrading from 14.04 to 16.04, this may be caused by skipping distributions and not having the correct updates to make the transition work smoothly this is not the correct way to upgrade from one distribution to another, in my option we should always have the currently version of Ubuntu to keep things stable and upgrade accordingly

I suggest backing up any important data and files, do a clean installation of 16.04 this way you will avoid these situation
