WARNING: qt 5.12.2 moving in

[devil]

As the headline says, Qt is being updated. That leads to the removal of hundreds of plasma packages. So please be careful until this is resolved.  In other news, Plasma 5.20.4 has been moved to Experimental by Norbert Preining. So we can expect it to move to Unstable soon, even if Norberts repos are not activated.

Wie die Überschrift aussagt, wird Qt aktualisiert. Das führt zur Entfernung von Hunderten von Plasma-Paketen. Seid bitte vorsichtig, bis das Problem behoben ist.  Zudem wurde Plasma 5.20.4 von Norbert Preining nach Experimental hochgeladen. Wir können also erwarten, dass es bald nach Unstable wandert, auch wenn Norberts Repos nicht aktiviert sind.

Topic typo, should be Qt 5.15.2 

[devil]

right, fixed.

151 to be removed here -- thanks for the warning.

I did 2 d-u and both systems are fine

[hendrikL]

Well, i think i will wait a bit longer

Code Auswählen Erweitern


The following packages will be REMOVED:
  kinfocenter kwin-addons kwin-common kwin-wayland kwin-wayland-backend-drm kwin-wayland-backend-fbdev kwin-wayland-backend-virtual
  kwin-wayland-backend-x11 kwin-x11 latte-dock plasma-desktop plasma-integration plasma-widgets-addons plasma-workspace plasma-workspace-wayland

Here in USA it is NOT yet safe to upgrade for persons using plasma desktop and don't use the Preining repo.

I just DU'd an LXqt laptop and a KDE desktop computer without loosing anything. Both completed without incident.   
 
Now I'm trying to decide whether I should heed Martin Steigerwald's call and pull in Plasma 5.20.4 from experimental and try it out on Debian.

You can help: Test Plasma 5.20.4 and test applications 20.12Martin Steigerwald martin@lichtvoll.de via lists.debian.org 1:37 PM (2 hours ago)

to debian-kde Hi!

If you are feeling adventurous and are using Sid, then you can help by
testing Plasma 5.20.4 from experimental. I installed it using

apt install -t experimental plasma-base

"plasma-base" is a new package to keep the versions of all Plasma
packages in lock step.

But beware currently Qt 5.15.2 is entering into Sid. It may need a day
or two to complete. Be extra careful during that time.

Also you can help test new application 20.12 packages as they enter
unstable. Use them and report any issues you find with them.

Please do this only if you feel up to it and are willing to keep the
pieces in case something breaks. Of course you can always ask for help
here, but it would be good if you are willing to do your best to resolve
and diagnose issues on your own first and then if need be report with as
much detail as possible.

If unsure whether it is really a Debian bug or you like to learn about
which package to report the bug for, feel free to ask here first.

So far I am very happy with Plasma 5.20.4 and those KDE application
packages I upgraded. I thank Norbert, Aurélien, Sandro who is in the
process to upgrade KDEPIM packages to 20.08.3, Dmitry and everyone else
who is involved with upgrading the packages or helps testing them.

Thank you,

Now I'm trying to decide whether I should heed Martin Steigerwald's call and pull in Plasma 5.20.4 from experimental and try it out on Debian.

Give it a try, maybe in a vbox or so.

I always have an eye on d-qt-kde and there seems to be no big glitches.
I use Norberts packing of kde/plasma and I have to wait till new kwin  (build against qt 5.15.2, maybe more) is uploaded.

[Taliesin]

Two systems updated safely here also.
Threads like this are invaluable.
My thanks to Devil for the initial warning, and to all who have contributed.

i waited a bit longer, until now, in order to get the dependency of calibre to become fine again. ran dist upgrade and everything is OK.

thanks for the warning!

So I installed that plasma from experimental, it works without a problem.
After I figured out what is needed so that no package get lost/removed all went fine and far as I can see there are no problems, at the moment™.

Here is what I have done (on other systems it could be similar but not the same).

Code Auswählen Erweitern


apt update

apt install -t experimental kinfocenter kwin-addons kwin-common kwin-wayland kwin-wayland-backend-drm kwin-wayland-backend-fbdev kwin-wayland-backend-virtual plasma-framework plasma-workspace kwin-x11 libqt5core5a libprocessui9 libqt5webenginecore5 libqt5webenginewidgets5

apt full-upgrade

@hendrikL's procedure and result confirmed.

Here occured a disturbing glitch, on the border between desktop background and plasma control bar.

[hendrikL]

Maybe a shadow, take a look to the settings (don't ask me where).

[Mte90]

I have the same glitch, just to say with latest plasma 20.04.
