I was on 16.04 LTS and just download the 18.0 LTS
I reboot and the result is Nothing! 16.04 again
Can you tell me what happened?
Thank you

Hi Patrick,

Welcome to our forums.

How did you performed the upgrade? There are many ways you can take - are you used one of the methods described in this guide?


#3

Hi Sandman
Yes I did and executed the update, the removal etc. before to start the upgrade
Some commands to launche and no trouble untill the end.
Than I restarted and had the 16.04 again as if I did nothing
:sob:
Tanks
Patrick

Thanks ! Not tanks as my corrector says😌


#5

Hey Patrick,

Did you use the graphical update manager or a command on the terminal? If the later, please execute it again and paste the output it provides here, so we can see where the problem may be. The last few lines from /var/log/apt/history.log could also show us some clues.

since I am a ‘Beginner’ I’m not allowed to copy a terminal screen on a post. It works with parts of it

I started again : sudo do-release-upgrade

Hi Patrick,

Please provide the output of the following command on the terminal:

echo $LANG

With that I can set up a close to identical lab environment.

#14

Hey Patrick,

At the last question, you answered with lowercase “o” and the do-release-upgrade exited without any further output?


#15

Hi Sandman
I did click “d” instead of “o” and run into a dead-end. no way out so I closed the terminal and opened again and executed echo $LANG the way you told me
sorry :frowning:


#16

Hey Patrick,

You have to press “o” to start the upgrade, “d” leads to the details of it. Let me know if running the do-release-upgrade again, and if everything seems okay starting it with “o” provides any errors, or starts the upgrade process as it should.

At the gnome terminal you can always hit ctrl+shift+t to open another tab on it and thus another terminal session while leaving the original one intact if it may be needed later.


#17

I do my best
:heart_eyes:


#18

Hi Sandman
there it goes again. the thing is running and doesn’t seem to have any trouble
i opened a second terminal screen as you suggested
:crossed_fingers:


#19

Hi Sandman
I am wheeping like a guitare
After the “o” command the computer started again and did his thing.
Now I have the HPblue screen (normal) Than the red UBUNTU with the five white dots that turn red. The screen turns black ant this is it. No acces anymore. A manual restart gives the same result. :rage:


#20

Hi Patrick,

To quote a classic: don’t panic, we are making progress. That is a huge step from “nothing happening”, at least from the upgrade perspective.

After the boot, the dots thing and the screen turning black, can you switch to another terminal by hitting something like ctrl+alt+F4? Getting a command line terminal asking for the login username would mean a success. That means only your X server has some sort of problem, but your system is running otherwise.
If that is so, please log in on the command line and check for the version with something like
cat /etc/os-release

In any case, please tell what happens on terminal switching.
