Tested on another laptop with same results.  I don't think I have a laptop with KDE Neon already installed.

Same bug for an existing installed KDE neon system.
The error message: "The following packages have unmet dependencies: qt6-webengine: Depends: liblcms2-2 (>= 2.16) but 2.14-2build1 is to be installed"

Comment 4 Carlos De Maine 2025-12-04 03:38:38 UTC 
apologies it is an apt pinning problem from the jammy to noble upgrade.  to upgrade the pins file it means a double upgrade:

sudo apt install neon-settings-2
sudo apt update
sudo apt dist-upgrade

should solve the problem

@Carlos: Sorry, not on my side. Did what you suggest but still get the error message. Reboot did not change anything.

This worked for me, on a fresh install.  Oh, I did check that there was still the problem package in Discover before running those three commands.  I did not see any errors in Konsole.  I rebooted, and Discover says "Up to date", even after a manual refresh.

In general, I thought, the "User Edition" of KDE Neon was only supposed to use the Discover app for all updates.  These machines are scratch machines, so I don't mind testing to help out.  Is it fixed in the 202512041319.iso?  If needed, I can do another install next weekend to test.

It works. Thanks!
