Hello,

I have tried to install QGIS in a fresh Kubuntu 16.04 and KDE Neon (which is also based on ubuntu 16.04) with no success, as I get the following error:

sudo apt-get install qgis python-qgis qgis-plugin-grass
Reading package lists... Done
Building dependency tree       
Reading state information... Done
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 to resolve the situation:

The following packages have unmet dependencies:
 python-qgis : Depends: python3-pyqt5.qsci but it is not going to be installed
 qgis : Depends: qgis-providers (= 1:3.0.0+24xenial-ubuntugis) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

I am currently using the following repos in a fresh environment (just installed kubuntu 16.04 and updated it, with no further software installed):

• deb https://qgis.org/ubuntugis xenial main
• ppa:ubuntugis/ubuntugis-unstable

Apparently other ubuntu non-KDE flavours are working fine with the same configuration.

Same problem here. I even tried the "build your own set of packages" option linked to at qgis.org/en/site/forusers/alldownloads.html#debian-ubuntu but still thwarted by unresolved dependencies.

I tried to install qgis versions 2.8.6, 2.18.16 and 3.2.2 on Linux Mint 18.3 (KDE flavour) which is also based on Ubuntu 16.04 (Xenial). Unfortunately with no success. There is some dependencies mess.

I was using repositories:
@deb https://qgis.org/ubuntu xenial main@
or
@deb https://qgis.org/ubuntu-ltr xenial main@
or
@deb https://qgis.org/ubuntugis xenial main@
or
@deb https://qgis.org/ubuntugis-ltr xenial main@

... and also default xenial universe repository.

In case of 2.8.6 and 2.18.16 there was dependency error:

qgis -> python-qgis -> python-qscintilla2 -> sip-api-11.3

sip-api required by python-qscintilla2 is a virtual package which is provided from python-sip package. Unfortunately for Ubuntu 16.04 the only version of python-sip that is available (4.17+dfsg-1build1) provides only the following versions of spi-api:
sip-api-11.0
sip-api-11.1
sip-api-11.2

The sip-api.11.3 is provided in python-sip (4.18.1+dfsg-2build1) or higher versions, so this means you have to use Ubuntu artful (17.10) or bionic (18.04)
https://packages.ubuntu.com/artful/sip-api-11.3

In xenial repositories there is only python-sip (4.17+dfsg-1build1): https://packages.ubuntu.com/xenial/python-sip

For qgis 3.2.2 there was more dependencies errors which could not be installed

gdal-abi-2-2-2
libgdal20 (>= 1.8.0)
libqgis-analysis3.2.2
libqgis-app3.2.2
libqgis-core3.2.2
libqgis-gui3.2.2
python-qgis (= 1:3.2.2+24xenial-ubuntugis)
qgis-providers (= 1:3.2.2+24xenial-ubuntugis)

For version 2.18.32 the list was similar (only different versions of packages).

There is also similar (I think) bug #25258.

Ok I found the solution for qgis 2.8.x and 2.18.x. The problem was python-qscintilla2 version 2.9.2+dfsg-3build1~~xenialoverlay1~1 from http://ppa.launchpad.net/kubuntu-ppa/backports/ubuntu which requires missing sip-api-11.3.

When I installed python-qscintilla2 version 2.9.1+dfsg-4build1 from default xenial universe repository the installation went fine and qgis is working (for now) without problems.

Still an issue?
