Ubuntu 14.04 to 16.04 Upgrade failed

14.04 upgrade 16.04

Solution 1

I think I fixed the error.

I reinstalled unity and ubuntu-desktop. I also had to enable desktop icons again (Ubuntu Tweak -> Tweaks -> Desktop Icons -> On). Everything looks normal again.

Solution 2

This worked for me after a botched sudo do-release-upgrade from 14.04 to 16.04. The updater's automatic attempt to restore to the previous version failed as well but left me at the terminal where I was able to complete the upgrade as follows.

1) Replace the contents of /etc/apt/sources.list with the following

###### Ubuntu Main Repos
deb http://us.archive.ubuntu.com/ubuntu/ xenial main universe 
deb-src http://us.archive.ubuntu.com/ubuntu/ xenial main universe 

###### Ubuntu Update Repos
deb http://us.archive.ubuntu.com/ubuntu/ xenial-security main universe 
deb http://us.archive.ubuntu.com/ubuntu/ xenial-updates main universe 
deb-src http://us.archive.ubuntu.com/ubuntu/ xenial-security main universe 
deb-src http://us.archive.ubuntu.com/ubuntu/ xenial-updates main universe

Optional) If you are receiving error insserv: Service mountdevsubfs has to be enabled to start service hwclock1, run the command sudo rm /var/lib/dpkg/info/util-linux.postinst

2) sudo apt-get update -- updates package lists

3) sudo apt-get dist-upgrade -- this will take a while, installs all the updated packages

4) sudo apt-get autoremove -- removes unnecessary packages

5) sudo apt-get autoclean -- cleans old packages from repository

6) sudo update-grub -- updates grub boot config

Now if you run sudo do-release-upgrade, you should get the response No new release found. and you can reboot with sudo shutdown -r now. After reboot, you might want to repeat steps 2 to 5 to be sure all updates are installed.

Solution 3

From the Official Ubuntu website: 14.04 LTS to LTS upgrades will be enabled with the 16.04.1 LTS point release, in approximately 3 months time.

If in a hurry, do a fresh install ;-)

Today I wanted to upgrade from LTS to LTS. I performed
```
update-manager -d 
```
and started the upgrade. However, after having downloaded all files and running the installation, the upgrade failed, or at least it failed partially. There is some erroneous behavior regarding graphics and window management. The two screenshots show the behavior, something similar to what we know from Windows...

I had the hope, that an additional
```
apt-get update
apt-get upgrade
```
would install remaining (potentially missing) packages, but the list is quite empty

```
and everything is installed. I have the impression, that I need to redo, or at least somehow continue the failed upgrade, but I don't know how to. The two approaches I tried didn't yield anything:
```
sudo apt-get -f dist-upgrade
```
says, there is nothing to install. And
```
sudo update-manager -d 
```
tells me, that I'm up to date.

Any ideas, how I can fix this problem?

After restarting multiple times, I notice that from time to time the applications also look differently, see the following screenshot.

  Did you try sudo do-release-upgrade?
- Thomas about 8 years
  
  This only gives Checking for a new Ubuntu release; No new release found

  What I'm wondering is Why do we still have a "precise" reference in there? (I also have it in my one upgraded computer!)
- user.dz almost 8 years
  
  Do you still have release upgrade info? Could you post sudo updatedb; locate apt-clone Also grep -n deb /etc/apt/sources.list /etc/apt/sources.list.d/*.list

  The output is: sudo updatedb; locate apt-clone /var/log/dist-upgrade/apt-clone_system_state.tar.gz The output of grep is pasted at pastebin.

I would prefer fixing my problem over a fresh install

You stated you wanted to upgrade from LTS to LTS. That option will only be available after te point release (checked and confirmed myself). Fresh installs are no biggie if you have a separate partition for home.

What's this apt command you speak of? Re-installing Grub won't fix graphics issues and configuring pending unconfigured packages only helps if packages related to the issue are installed but not configured (which is not the case as far as we can tell). -1

This worked for me. I think it would have fixed the posters issue. The OP did not need the recovery and grub part, but others might.

This worked great for me when I encountered launchpad.net/bugs/798414 during a do-release-upgrade (a full /boot partition), thanks!
