QGIS installation instructions fail

Question

This is the "instructions box" at https://qgis.org/en/site/forusers/alldownloads.html (example of debian-ubuntu instruction for ),

The last red line is the problem, with no explicit instruction and it seems where my apt install fails, because it resulted in an old "3.22.4-Białowieża" version, instead of a new version new 3.32 version.

How to add the red line?

The instructions say nothing, only describes that the last wget command "Add the QGIS repo for the latest stable QGIS (3.32.x Lima) to /etc/apt/sources.list.d/qgis.sources"... But it is false, there is no /etc/apt/sources.list.d/qgis.sources (error "No such file or directory").

With no extra procedure for the red line it also runs

1. sudo apt update (Ok)
2. sudo apt install qgis qgis-plugin-grass (Ok but install bad version!!)

I need a new version.

Fail in the first clues

First clues posted by @bugmenot123 also fail (!).

1. I created the "red line file" by sudo cat > /etc/apt/sources.list.d/qgis.sources
2. I do copy/paste of the supposed content
3. I do again apt update (after apt purge qgis) and it fails:

Get:10 http://archive.ubuntu.com/ubuntu jammy-updates/universe amd64 DEP-11 Metadata [274 kB]
Err:11 https://debian.qgis.org/debian your-distributions-codename Release                    
  404  Not Found [IP: 2606:4700:3035::6815:4729 443]
...
E: The repository 'https://qgis.org/debian your-distributions-codename Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.

PS1: please at answer say also how to purge the old installed v3.22.4.

PS2: lsb_release -cs for my Linux results in "jammy" (and it exists at QGIS as https://debian.qgis.org/debian/dists/jammy/)

Answer 1

If you don't have a /etc/apt/sources.list.d/qgis.sources file yet, you can simply create it.

Either use an editor like nano, mousepad, geany etc to edit the file directly:

sudo YOUREDITOR /etc/apt/sources.list.d/qgis.sources

or create a qgis.sources text file with your normal user using any text editor and then move it using sudo mv qgis.sources /etc/apt/sources.list.d/

Purging a package using apt is done by apt purge packagename, so e.g. apt purge qgis.

qgis.sources file is a template

You need to fill the Suites value:

Types: deb deb-src
URIs: https://qgis.org/debian
Suites: $your_distributions_codename
Architectures: amd64
Components: main
Signed-By: /etc/apt/keyrings/qgis-archive-keyring.gpg

So, replace the placeholder $your_distributions_codename by "jammy" (that was in your case the result of lsb_release -cs).

Suites: jammy

Answer 2

I did

sudo wget -O /etc/apt/keyrings/qgis-archive-keyring.gpg https://download.qgis.org/downloads/qgis-archive-keyring.gpg

sudo nano /etc/apt/sources.list.d/qgis.list

# in nano
deb [arch=amd64 signed-by=/etc/apt/keyrings/qgis-archive-keyring.gpg] https://qgis.org/debian <codename> main
deb-src [arch=amd64 signed-by=/etc/apt/keyrings/qgis-archive-keyring.gpg] https://qgis.org/debian <codename> main
