Release: Ubuntu 22.04 LTS
Kernel: 5.15.0-1005-raspi
Package: qtvirtualkeyboard-plugin
Version: 5.15.3+dfsg-1
I encounter errors when trying to use a QT Application with `qtvirtualkeyboard-plugin`. The application source is on Github: https://github.com/OpenVoiceOS/ovos-shell. Below is the gdb output that identified this package as the problem.
I tried building the package from source, but was unable to continue when build packages conflicted with system dependencies. There is already a thread on the Qt forums discussing this: https://forum.qt.io/topic/137839/issues-installing-qtbase5-private-dev-on-an-ubuntu-22-04-system/8.
