Ubuntu 25.04 - Qt virtualkeyboard package

Support and Help

1

Ubuntu Version:
25.04

Desktop Environment (if applicable):
N/A (Docker)

Problem Description:
I have upgraded my Docker image from “ubuntu:24.10” to “ubuntu:25.04”.
I am no longer able to install the following packages via apt install:

  • libqt5virtualkeyboard5
  • qtvirtualkeyboard-plugin
  • qml-module-qtquick-virtualkeyboard

The error states that the packages can not be found. Using apt search <package-name> also yields no results anymore.

Relevant System Information:
Docker image “ubuntu:25.04”

Screenshots or Error Messages:

What I’ve Tried:
I have asked LLMs and my search engines of trust whether they know something about these packages disappearing from the package indexes (with no result).
I have searched on https://pkgs.org for these packages, but they are also reported there to be only available until 24.10

I am not too experienced with Ubuntu, therefore I do not know if there is a better suited forum to ask this question.

Ubuntu 25.04 is using Qt6, thus the package available there is https://packages.ubuntu.com/plucky/libqt6virtualkeyboard6 for your first package, and the second is available via https://packages.ubuntu.com/plucky/qt6-virtualkeyboard-plugin

Its not clear to me why you’re after them, as you’re chasing older packages using the older toolkit (Qt5) not the newer toolkit (Qt6). Are you wanting them to run older software?

Yes, I want to run an application that is still being developed using Qt5.
What is strange to me: I can install fine the following packages:

libqt5concurrent5 \
        libqt5core5a \
        libqt5charts5 \
        libqt5dbus5 \
        libqt5gui5 \
        libqt5network5 \
        libqt5printsupport5 \
        libqt5sql5 \
        libqt5test5 \
        libqt5widgets5 \
        libqt5xml5 \
        libqt5svg5 \
        libqt5qml5 \
        libqt5quick5 \
        libqt5quickcontrols2-5 \
        libqt5quickwidgets5 \
        libqt5quickshapes5 \
        libqt5quickparticles5 \
        libqt5webview5 \
        qt5-image-formats-plugins \
        qttranslations5-l10n \
        qtwayland5 \
        qml-module-qtcharts \
        qml-module-qtquick2 \
        qml-module-qtquick-controls \
        qml-module-qtquick-controls2 \
        qml-module-qtquick-dialogs \
        qml-module-qtquick-extras \
        qml-module-qtquick-layouts \
        qml-module-qtquick-localstorage \
        qml-module-qtquick-particles2 \
        qml-module-qtquick-pdf \
        qml-module-qtquick-scene2d \
        qml-module-qtquick-shapes \
        qml-module-qtquick-window2 \
        qml-module-qt-labs-platform \

The virtualkeyboard is the only package not available anymore and I am wondering why.

Qt5 maybe dropped in its entirety before Ubuntu 26.04 LTS released; refer Removing Qt 5 from Ubuntu before the release of 26.04 LTS

I’m not a developer, but I’d imagine it’s easier to remove parts sooner than removing it all at once, thus you may find more dropped in 25.10 too.

Details on removal (in plucky) of the qtvirtualkeyboard package can be viewed at Publishing history : qtvirtualkeyboard-opensource-src package : Ubuntu as per Bug #2100646 “Please remove from Plucky to follow Debian (Qt 5 l...” : Bugs : qtremoteobjects-everywhere-src package : Ubuntu

ps: Simon Quigley who’ll you’ll find referenced in those reports, is a Debian developer, with Ubuntu and Debian working together, but Debian trixie (13) will released before Ubuntu 26.04 LTS releases.
