Doesn't tell me much, but since "sip" is the last package mentioned and easy to type, I tried updating that one by itself:

# dnf update sip --best
Last metadata expiration check: 0:12:45 ago on Thu Jan 26 08:44:43 2017 EST.
Error: problem with installed package pykde4-4.14.3-14.fc26.x86_64
  - package pykde4-4.14.3-14.fc26.x86_64 requires sip-api(11) >= 11.3, but none of the providers can be installed
  - package pykde4-4.14.3-14.fc26.x86_64 requires sip-api(11) >= 11.3, but none of the providers can be installed
  - package pykde4-4.14.3-14.fc26.x86_64 requires sip-api(11) >= 11.3, but none of the providers can be installed
  - cannot install both sip-4.19-1.fc26.x86_64 and sip-4.18.1-2.fc26.x86_64
  - cannot install the best update candidate for package sip-4.18.1-2.fc26.x86_64
(try to add '--allowerasing' to command line to replace conflicting packages)
# rpm -q --requires pykde4| grep sip
sip-api(11) >= 11.3
# rpm -q pykde4
pykde4-4.14.3-14.fc26.x86_64
# rpm -q --whatprovides sip-api\(11\)
sip-4.18.1-2.fc26.x86_64



I downloaded the latest sip rpm from the repo to see what it provides:
# rpm -qp --provides /data/downloads/sip-4.19-1.fc26.x86_64.rpm
sip = 4.19-1.fc26
sip(x86-64) = 4.19-1.fc26
sip-api(12) = 12.0
sip-api(12)(x86-64) = 12.0
#


Based on the above, it looks like pykde4 requires sip-api(11) which is provided by sip-4.18.1-2.fc26.x86_64. When that sip package gets updated, it provides sip-api(12) instead of sip-api(11). You'd think that'd be good enough, but the pykde4 requires a sip-api(11) >= 11.3, not sip-api >= 11.3. 

Version-Release number of selected component (if applicable):
sip-4.18.1-2.fc26.x86_64
pykde4-4.14.3-14.fc26.x86_64
dnf-2.0.0-2.fc26.noarch

How reproducible:
100%

Steps to Reproduce:
1. dnf update
2.
3.

Actual results:
Errors as shown above

Expected results:
dnf update works correctly

Additional info:
I'm not sure if this an issue with dnf that it should be able to see that sip-api(12) is good enough for sip-api(11) >= 11.3 or if pykde4 should require sip-api(anything) >= 11.3 rather than needing sip-api(11) (maybe there's something in sip-api(12) that doesn't work in pykde4 so that's why it needs sip-api(11) >= 11.3?)

Comment 1 Rex Dieter 2017-01-26 18:06:16 UTC
it's simply that sip(11) is not equal to sip(12).  pykde4 needs rebuilding, and unfortunately, the build currently fails, last attempt:

Comment 2 Rex Dieter 2017-01-26 18:09:06 UTC
Items in the distro that still depend on pykde4 (according to repoquery), include:

autokey-qt
kajongg
lekhonee
pony

which is impacted by this.

Comment 3 Rex Dieter 2017-01-26 20:00:27 UTC
Alternatively, I'd been considering ways of packaging parallel-versions of sip, so legacy bindings (like pykde4) could continue working with the old, while newer releases (like python-qt5) can use newer/latest versions.

Comment 4 Rex Dieter 2017-01-26 21:06:55 UTC
Good news, found a fix upstream, doing test builds now.

Comment 5 Rex Dieter 2017-01-26 21:34:46 UTC
yay, it worked,
