Upgrading from Q4OS 2.4 to Q4OS 2.5

Is it possible to upgrade Q4OS 2.4 to Q4OS 2.5 without reinstalling whole system ? I would keep Trinity desktop without installing KDE Plasma 5.8 LTS. I have un very old portable and Q4OS is fine for this old computer. I don't know if it is interresting for me to upgrade to 2.5.
If yes, is it possible to upgrade with command lines in the terminal ? in mode superuser ?
Many thanks and sorry for my poor english (I am french...).

Hi Harry, you should be fine to update to Version 2.5 in the usual update manner, you will not be forced to install Plasma or anything else as it is totally optional. And updating as superuser is as simple as

apt update && apt upgrade

There may be one or two subtle differences in the system by upgrading rather than re-installing but it is likely not noticeable.

Yes, it is. Automatic updates will take care about 2.4 -> 2.5 upgrade, you don't need to do anything. If you have disabled automatic upgrades, you can trigger the update manually using Synaptic package manager or from terminal:
$ sudo apt update
$ sudo apt dist-upgrade

-

I would keep Trinity desktop without installing KDE Plasma 5.8 LTS.

Don't worry about that, Plasma desktop will not be installed, unless you  explicitly ask to install it.

I don't know if it is interresting for me to upgrade to 2.5.

Yes, we would recommend you to upgrade, please see answers above.

You can check the current Q4OS version in terminal:
$ get-q4os-version

Re: Upgrading from Q4OS 2.4 to Q4OS 2.5

Many thanks to Dai_trying and q4os Team for your prompt replies.
I have checked my current version in terminal and the reply is : 2.5.1-n1
I have updated some files this morning and I think that the updater has installed the last version.
Do I have to do another thing ?
Thanks
Harry

Hi,

You say "Plasma desktop will not be installed, unless you  explicitly ask to install it"

How do you explicitly ask to install it?

I am keen to try it, thanks.

Well I am not sure what happened but when I rebooted KDE desktop was installed so it seems all is well.

Re: Upgrading from Q4OS 2.4 to Q4OS 2.5

@Jedi
You have added a few alien repositories into your system, for ex.:

http://ppa.launchpad.net/libreoffice/ppa/ubuntu cosmic
http://ppa.launchpad.net/teejee2008/ppa/ubuntu bionic
http://ppa.launchpad.net/webupd8team/java/ubuntu bionic

It's not recommended and most likely results in broken packages dependencies. We would recommend you to remove such repositories and run fix script, please see https://q4os.org/dqa011.html#system.1

Re: Upgrading from Q4OS 2.4 to Q4OS 2.5

You can check if they exist in the file /etc/apt/sources.list and if so remove them (you can simply delete this file if it only contains these entries)

If they are not (all) in this file you should look in the folder /etc/apt/sources.list.d/ and find any files that contain these entries and remove them. It is difficult to give more precise information as we do not know how you added these sources in the first place. Hope this helps.

Once they are all removed you should run sudo apt update to refresh your apt db information, then you should run the procedure posted by the Dev Team
