SUMMARY

'QGIS 3.10.4+dfsg-1ubuntu2 (focal)' won't install on KDE Neon.  I tried both before updating from 18.04 to 20.04 and after, and I also tried a fresh install of neon-user-20200815-2050.  I tried both Discover and Synaptics Package Manager.  

In contrast, QGIS installs OK with Kubuntu 20.04.  

The KDE Neon installation fails on package 'qgis' broken dependencies: specifically, package 'qgis', 

Conflicts: uim-qt3
Breaks: qgis-common (<3.4.5)
Breaks: qgis-provider-grass (<2.14.0)
Recommends: qgis-provide-grass
Suggests: gpsbabel
Replaces: qgis-common (<3.4.5)
Replaces: qgis-provider-grass (<2.14.0)
  

STEPS TO REPRODUCE
1. Install neon-user-20200815-2050.iso
2. Open Discover or Synaptics Package Manager
3. Attempt to install QGIS

OBSERVED RESULT

Discover reports "Dependency resolution failed"; Synpatics reports QGIS is broken. 

EXPECTED RESULT

QGIS installs

N.B. Andrew-63 was having a similar problem with KDE Neon 18.04 - https://gis.stackexchange.com/questions/351962/problem-installing-qgis-3-12-on-linux-kde-neon .

Definitely Neon issue:

Comment 3 Peter 2021-02-18 21:00:43 UTC

Following an update recently - not sure exactly when - the problem is resolved, and QGIS3.10 has installed perfectly.  

I don't know who to thank, but thank you.

Thank you for your bug report! 
However this bug report was created/provided previous to 01/01/2023 and also has not received any updates since  before 01/01/2025. 
Unfortunately KDE neon no longer provides updates for anything older than noble 24.04 based edition's.
Please upgrade to KDE neon noble and if you can reproduce the issue after upgrading to an active version, feel free to re-open this bug report.
Thanks for understanding!
