No init after do-release-upgrade from 14.04 to 16.04 (kernel panic)

Just found there might be some information in /var/log/dpkg.log and /var/log/dist-upgrade/, I'll dig there when I find some time.

Thank you for taking the time to report this bug and helping to make Ubuntu better. It seems that your bug report is not filed about a specific source package though, rather it is just filed against Ubuntu in general. It is important that bug reports be filed about source packages so that people interested in the package can find the bugs about it. You can find some hints about determining what package your bug might be about at https://wiki.ubuntu.com/Bugs/FindRightPackage.

I'm glad to see some activity on this report, however I'm afraid it will be difficult to investigate further, because I installed a fresh 16.04 since then.

All I can say is I chrooted on the root partition from a live CD and tried to upgrade with apt, and figured the installation was completely broken with unsolvable conflicts. Not only fcitx, but dozens of dependencies.

Sorry I can't give more insight, I didn't have much time to investigate further and it didn't occur to me to keep logs.

I have just been recovering a system that failed to upgrade from 14.04 to 16.04 with the same error as the OP. The solution was to chroot in from a liveCD following the Update Failure instructions.

After an apt-get update, apt-get upgrade, apt-get dist-upgrade and apt-get -f install the system could be booted normally, albeit without a working X-environment and package dependancy issues.

The package dependancy issues (mostly in Latex-related packages, with it trying to both upgrade and install tex-common as part of an "apt-get -f install", and libboost) were resolved by removing the offending packages and their dependancies with "dpkg --remove --force-remove-reinstreq <packagename>".

apt-get update and upgrade then worked and the system booted with a working X-Environment.

First thing to do is:
1- boot your linux distribution on USB or CD
2- live boot your system on the USB or CD key
3- in command line type: **mount /dev/sda1**(or your dist partition) **/mnt**
4- **chroot /mnt5- nano /etc/resolv.conf** (in this file, put this line: **nameserver 8.8.8.8**)
6- **apt-get install init**

after reboot your system. It will work fine. Enjoy

This worked for me (note that I had a 7th step to update initramfs just in case):

1. boot your droplet with a Recovery ISO - Like TigerShark from DigitalOcean
2. Network must be configured, either manually or via TigerShark script.
3. $ mount -rw -o remount /dev/vda1 /mnt
4. $ chroot /mnt
5. $ unlink /etc/resolv.conf && echo "nameserver 8.8.8.8" > /etc/resolv.conf
6. $ apt-get install init
7. $ update-initramfs -u

After reboot your system. It will work fine. Enjoy! ;)
