Hi all, I hope this is the correct place to report this - In short, I'm building cleanroom chroots on KDE Neon user/lts packages - about 24 hours ago, I began getting build failures: > The following packages have unmet dependencies: > python3-pykde4 : Depends: sip-py3api-11.2 Digging into this, 1. python3-pykde4 is an ubuntu provided package 2. the missing dependency is provided by python3-sip, a neon provided package For reasons beyond my understanding, python3-pykde4 is not taking any notice of the python3-sip Provides which satisfies the sip-py3api-11.2 dep # apt-cache policy python3-pykde4 python3-pykde4: Installed: (none) Candidate: 4:4.14.2-0ubuntu6 Version table: 4:4.14.2-0ubuntu6 500 500 http://aptmirror.debortoli.private:3142/archive.ubuntu.com/ubuntu xenial/universe amd64 Packages # apt-cache policy python3-sip python3-sip: Installed: 4.19.2+dfsg-1+16.04+xenial+build3 Candidate: 4.19.2+dfsg-1+16.04+xenial+build3 Version table: *** 4.19.2+dfsg-1+16.04+xenial+build3 500 500 http://archive.neon.kde.org/user/lts xenial/main amd64 Packages 100 /var/lib/dpkg/status 4.18.1+dfsg-2+16.04+build3 500 500 http://archive.neon.kde.org/user/lts xenial/main amd64 Packages 4.17+dfsg-1build1 500 500 http://aptmirror.debortoli.private:3142/archive.ubuntu.com/ubuntu xenial/universe amd64 Packages ** I used this aptitude search command to see what packages provide sip-py3api-11.2, and their installation status: # aptitude search '~Psip-py3api-11.2' i python3-sip - Python 3/C++ bindings generator runtime library p python3-sip:i386 ** So with everything ready to go, deps satisfied by virtual packages, I should be able to install python3-pykde4: # apt-get install python3-pykde4 Reading package lists...

Ok, I've worked it out what's actually going wrong. Apologies, lack of sleep and soforth: "python3-pykde4" is an ubuntu provided package, that depends on a virtual package "sip-py3api-11.2" provided by python3-sip (< 4.19) The neon repositories now include python3-sip=4.19.2+dfsg-1+16.04+xenial+build3 but this does not provide "sip-py3api-11.2" # apt-cache show python3-sip | egrep -e ^Provides -e ^Version Version: 4.19.2+dfsg-1+16.04+xenial+build3 Provides: sip-py3api-12.0, sip-py3api-12.1 ... Is it possible to build python3-sip to include provides for sip-py3api-11.X AND sip-py3api-12.X?
(In reply to Bernard Gray from comment #1) > Is it possible to build python3-sip to include provides for sip-py3api-11.X > AND sip-py3api-12.X? Alternatively, can neon start including compatible builds of python3-pykde4 in their repos?
All this means is that pykde4 (and possibly pyqt4) need to be rebuilt in the neon repositories against the current sip4. There's no upstream issue here.
Hi Scott, Thanks for the reply. I apologise, but I thought this bugtracker is where I would make neon related requests. I gather from your post that I was wrong - can you point me in the direction of where I should post my request to rebuild python3-pykde4?
Honestly, I don't know. I don't have anything to do with Neon, but this isn't a KDE bug, it's a bug in their packaging.
Moving to neon.
I've done a bit more digging: I ended up finding the following bug/patch on the NixOS github project: https://github.com/NixOS/nixpkgs/issues/24548 https://github.com/NixOS/nixpkgs/commit/8c9b60a8307b4dafffb894b3d652389f6079b68a "This package is broken since 0a3b7f9 (python-sip: 4.18.1 -> 4.19.1). Removing it seems reasonable since we're dropping KDE4 anyway." I suspect that this is precisely what Neon is doing too, although I don't know where to find evidence of it. I've ended up migrating my in-house python package to PyQt5 anyway since finding this :)
yes the new sip needed for qt 5.9 breaks current build of pykde4. However I couldn't get pykde4 to build with latest sip/kdelibs/whatever /usr/include/kautomount.h:105:5: error: ‘KAutoUnmount::~KAutoUnmount()’ is private http://build.neon.kde.org/job/xenial_release_forks_pykde4_bin_amd64/1/console

I had the same issue trying to build pykde4, the packages that depend on it are pretty thin on the ground now, is it worth just committing to it's removal for neon? python3-pykde4 Reverse Depends: python3-pykde4-dbg update-manager-kde apturl-kde update-manager-kde python3-keyring python3-keyrings.alt gdebi-kde apturl-kde
