I think siduction is loosing the plot. It is meant to be totally compatible with sid which this thread illustrates it is not. The devs should be supporting upgrading KDE with pure Debian repros only, not an incompatible bespoke siduction/Ubuntu repro. I think a lot of users of kdenext will only be prolonging their transition back to kde sid. There are plenty of other desktops available to use while waiting for KDE to emerge from the current transitional chaos. A lot of the current problems could have been avoided if the kdenext thread had been put into the experimental section of the forum and the main support for the gcc and qt5 transition pinned at the top of the upgrade section.
kdenext is optional, and for that matter you don't even have to use towo's kernels, right?
But there are many users who appreciate both of these contributions and don't want to use "other" desktops either.
And please, people, let's be careful about suggesting other people what to use, because while there are "plenty of other desktops available to use" (it's not like we don't know that), one can say there are plenty of other distributions and operating systems. One can even claim to another fellow forum member they can live without any of the packages/software they currently use and rely upon, because see, "we don't use them we're OK".
But if we go in that direction, where will we end up?
Also, the current situation isn't about "an incompatible bespoke siduction/Ubuntu repro" but due to Debian's
GCC 5 transition (please read the linked broadcast to the Debian mailinglist). This transitions is far from over yet (
at 39% currently, as you can see).
