STEPS TO REPRODUCE 1. Just doing a normal upgrade via Discover 2. 3. OBSERVED RESULT <html>Dependency resolution failed:<br/><br/>The following packages have unmet dependencies: qt6-webengine: Depends: liblcms2-2 (>= 2.16) but 2.14-2build1 is to be installed </html> EXPECTED RESULT No errors. SOFTWARE/OS VERSIONS Operating System: KDE neon User Edition KDE Plasma Version: 6.5.2 KDE Frameworks Version: 6.19.0 Qt Version: 6.9.3 Kernel Version: 6.14.0-35-generic (64-bit) Graphics Platform: X11 Processors: 20 × 12th Gen Intel® Core™ i7-12700H Memory: 16 GiB of RAM (15.3 GiB usable) Graphics Processor 1: Intel® Graphics Graphics Processor 2: NVIDIA GeForce RTX 3060 Laptop GPU ADDITIONAL INFORMATION
Due to this error "The following packages have unmet dependencies: qt6-webengine: Depends: liblcms2-2 (>= 2.16) but 2.14-2build1 is to be installed" I cannot update my system via discover. Is there a fix or workaround for this? I've had no problems in the past with applying upgrades to KDE neon via discover. I now have two systems complaining about unmet dependencies.
I also have just the standard entries in /etc/apt/sources.list, e.g. deb http://archive.ubuntu.com/ubuntu/ noble main restricted universe multiverse deb http://security.ubuntu.com/ubuntu/ noble-security main restricted universe multiverse deb http://archive.ubuntu.com/ubuntu/ noble-updates main restricted universe multiverse
I think this may be the solution sudo apt install neon-settings-2 sudo apt update sudo apt dist-upgrade See https://bugs.kde.org/show_bug.cgi?id=512669
Confirmed, the following solved the problem. sudo apt install neon-settings-2 sudo apt update sudo apt dist-upgrade
