Upgrade from ubuntu 15.10 to 16.04 is stuck

Question

I have been running the upgrade from 15.10 to 16.04 for 10 hours now and it is stuck on the following screen:

Also, I can not open the terminal to with the small arrow to see what is going on. Any help appreciated.

Solution 1

I'm assuming it ran into a dependency issue or conflict and locked up or crashed :(... not much now you can do but reboot

You can maybe try to go to advanced options in the grub menu and choose recovery mode .. then get to command prompt and use

sudo apt-get install -f

to try to fix any package problems before you try to boot again. Hopefully you will be able to boot and try the upgrade again

Solution 2

First it is necessary to kill the process which is stuck (using htop search for distupgrade). Then boot to the regular kernel of ububtu 15.10 from grub. After that run:

sudo apt-get update
sudo apt-get upgrade
sudo apt-get autoclean
sudo apt-get autoremove
sudo apt-get dist-upgrade

This is what worked for me.

If it helps, I was running a 4.5.0 custom kernel prior to the upgrade.

I managed to kill the process of the update and it seems no damage was done. Right now I tried to reboot into the regular kernel of 15.10 and do the upgrade from there.

good luck hopefully it will run without locks this time :)
