On kubuntu 24.04 I have Python 3.12.3 installed. Is it possible to go back to install Python 3.11 ?

Hello

I am on Kubuntu 24.24, and I try to follow a guide named
How to transform your KDE plasma look like macOS

In one step I try to install Albert launcher but

sudo apt install albert
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
albert : Depends: libpython3.11 (>= 3.11.0) but it is not installable
E: Unable to correct problems, you have held broken packages.

So asking

hi@hi-z97nwifi:~/Downloads/MacSonoma-kde/sddm$ python3 -V
Python 3.12.3

This is why I ask this may be stupid question

I would not mess with the system install of python at all. One can descend into dependency hell all to easily. See the xkcd comic.

On my 24.04,

$ sudo apt install albert

This suggests you have added a repository for albert. The "official packages" on the albertlauncher github has only Elementary, Mint, and PopOS!; IIUC they may not work with Kubuntu.

If it was me, I'd try building from source inside a Python venv.

To get Albert, you probably wake to follow their own instructions.
https://albertlauncher.github.io/installation/

Which leads to here

We have no idea what page you are following, or how old or reliable it is. The Deb you have or it's source looks to be for an older version of Ubuntu.

Hello jlittle
thank's for https://xkcd.com/1987/
I appreciate !

Hello claydoh
I found conda
https://greenwebpage.com/community/h...-ubuntu-24-04/
With conda I was able to install python 3.11.10
then install Albert
and go back to previous 3.12.3
then desinstall conda

Thank you

Well that was the long and hard way to install this


. All you needed was the way to get the package for Albert that was made specifically for (K)Ubuntu 24.04, which works with your stock Python version., and not muck with things at all.

Hello Claydoh
Albert in previous install was not working right
I just followed your plan and it's much fast to install
