Installed a fresh up to date Neon in a vm and got the same error I got during my original install, and my workaround doesn't work I guess as I get the same error when I run it as I do on my main system.

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 resolve the situation:

The following packages have unmet dependencies:
 qgis : Depends: qgis-providers (= 1:3.4.1+28bionic) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

Package qtbase-abi-5-9-5 is a virtual package provided by:
  libqt5core5a 5.9.5+dfsg-0ubuntu1 [Not candidate version]

E: Package 'qtbase-abi-5-9-5' has no installation candidate

So I tried a workaround by making a fake package for qtbase-abi-5-9-5 (similar to https://gis.stackexchange.com/a/264244 ) since it's just a virtual package for libqt5core5a, which is installed.

user@kdeneon:~/tmp$ cat tmp.txt

and then got qgis to install but I still get an error when I run it.

So then I tried using pip to install pyqt5

Is there a problem with my workaround? How should python/pip/sip be configured?

So I think it's an issue with KDE Neon (and Kubuntu). I've seen several other python-based apps that don't work anymore. The latest Neon is based on ubuntu 18.04 (bionic) but uses libqt5core5a 5.11.2. But ubuntu only has 5.9.5 in the bionic repo and 5.11.1 and above is in the cosmic repo.

https://packages.ubuntu.com/bionic/libqt5core5a (5.9.5)
https://packages.ubuntu.com/cosmic/libqt5core5a (5.11.1)

and downgrading isn't an option :(

plasma-desktop : Depends: libqt5core5a (>= 5.11.2+dfsg)

I guess qgis 3.4.1 needs qt 5.9.5? My fake package pointing to 5.11.2 obviously didn't work...

Found a similar bug for qgis 3.2.0 where an update of pyqt5-common (5.10.1-7 -> 5.11.2-1) caused qgis to stop working. The bug was closed as "fixed" with no explanation of the solution.
https://bugs.archlinux.org/task/59291

For fun I tried:

$ pip3 install 'pyqt5==5.10.1'
...
Successfully installed pyqt5-5.10.1 sip-4.19.8

RuntimeError: qgis._gui cannot import type '����' from PyQt5.QtCore

I'm running it without Python support for now. But I notice I can't see layers anymore if I move them to a group. Is that related to this bug?

QGIS installs successfully on a Ubuntu 18.04.1 vm. I compared the following directories and found no difference in file contents:

~/.local/share/QGIS/QGIS3/profiles/default/python
/usr/share/qgis/python
/usr/lib/python3.6 (differnt cache)
/usr/local/lib/python3.6

Why won't it run?

These are the only differences in packages between Neon and Ubuntu:

Got it working by copying
