[Qgis-user] sip-api-11.2 and qtbase-abi-5-5-1 prevent installing qgis 2.99 nightly on kde neon / ubuntu 16.04

[Jason Paul Joines]

         I am running KDE Neon User Edition 5.11.4 on the amd64 version of 
Ubuntu 16.04.3.  I would like to test the nightly build of QGIS 2.99, but 
cannot install it due to dependency problems.  In particular, it seems 
like the problem is that the virtual packages sip-api-11.2 and 
qtbase-abi-5-5-1 are not available.

         I am trying to install via these repositories:

deb http://qgis.org/ubuntugis-nightly xenial main
deb http://ppa.launchpad.net/ubuntugis/ubuntugis-unstable/ubuntu xenial 
main

         I purged my existing QGIS (2.18.5) and GRASS versions before 
attempting the install.  First it seems like the install does not attempt 
to install depedencies:

# apt-get install qgis

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:
  qgis : Depends: libqgis-app2.99.0 but it is not going to be installed
         Depends: libqgis-gui2.99.0 but it is not going to be installed
         Depends: python-qgis (= 
1:2.99.0+git20171229+63c19256+24xenial-ubuntugis) but it is not going to 
be installed
         Depends: qgis-providers (= 
1:2.99.0+git20171229+63c19256+24xenial-ubuntugis) but it is not going to 
be installed
         Recommends: qgis-plugin-grass but it is not going to be installed

         I checked held packages and only have FireFox held.  I assume that 
is not the problem with QGIS:

# dpkg -l | grep '^h'
hi  firefox 
1:56.0+build6-0ubuntu0.17.04.1                             amd64 
Safe and easy web browser from Mozilla
#

         Then I specified the unmet dependencies to the installer, but have 
problems with unmet dependencies of the QGIS dependencies:

# apt-get install qgis libqgis-app2.99.0 libqgis-gui2.99.0 python-qgis 
qgis-providers

         I specified those dependencies as well:

# apt-get install qgis libqgis-app2.99.0 libqgis-gui2.99.0 python-qgis

         This seems to suggest that the underlying problem is with the 
packages sip-api-11.2 and qtbase-abi-5-5-1.  The latter is supposed to be 
supplied by libqt5core5a.  I have that package installed, but a newer 
version:

         I also have a newer version of python-sip, which is supposed to 
provide sip-api-11.2:

# dpkg -l python-sip

         Trying to force things does not seem to help:

         Is there a workaround to avoid these two virtual packages?


Thanks,
