Clicked "Upgrade"on Software Updater, yet button does nothing...

[yatski]

Software Updater prompted me that there is new LTS version available...(from 22.04 to 24.04.1)
Yet when I click "Upgrade"-button, nothing happens.

This is old Sony Vaio that has noveau driver. (used to have nvidia but there was compatibility problems)

Already tried "sudo apt upgrade" without real results.

0 upgraded, 0 newly installed, 0 to remove and 9 not upgraded.

(Problem in this is it prevents me updating anything else...)

I do not use software-updater but I think it simply updates any packages installed to the most recent version of that package for the OS version running, in your case 22.04. It does not update from one OS version to the next which is carried out differently.

I have never updated my OS version but always clean installed tyh enew version so will leave it to others to tell you what is the best method to use.

Failure to start the upgrade can be caused by held packages. I would check for any held packages by running:

apt-mark showhold

in the terminal. If there is any output, you have to remove the hold on each package shown:

sudo apt-mark unhold package-name

and then run:

sudo apt upgrade

again.
Also, to clean things up, I would also remove the packages that are no longer required on your system with:

sudo apt autoremove

Then start Software Updater and try the upgrade button again.

Command

apt-mark showhold

produces no results. Is this intended?

Command

if there is no output, there are no held packages. So held packages are not the problem.
Were you shown a message like one of the attached images after updating? If so, and the Upgrade button still doesn't work, I am not sure of the cause, but I suspect there is some issue with one or more of the packages that have been held back.

You may get more information by running:

sudo do-release-upgrade

in the terminal. Try that.

I tried

heta@heta-vaio:~$ sudo do-release-upgrade
[sudo] password for heta:

heta@heta-vaio:~$

I was shown message similar to the first picture, but there wasn't message similar to second picture. (There was no second dialog box at all.)

Ok, Instead of upgrading 22.04 with sudo apt upgrade, I would try updating with:

sudo apt full-upgrade

The difference between 'upgrade' and 'full-upgrade' options is that the latter can remove packages if needed to upgrade the system:

here is the description of this option from manpage of apt:

full-upgrade (apt-get(8))
full-upgrade performs the function of upgrade but will remove
currently installed packages if this is needed to upgrade the
system as a whole.

Ok, Instead of upgrading 22.04 with sudo apt upgrade, I would try updating with:

sudo apt full-upgrade

Ran command, updated packages and tried Software Updater.... Still no second dialog box.

Maybe my laptop is too old?

[Dennis N]

After running sudo apt full-upgrade, did you try

sudo do-release-upgrade

again?

Got this:

heta@heta-vaio:~$ sudo apt full-upgrade
