Ubuntu 17.10에서 18.04로 업그레이드하면 Textstudio/Qt가 중단됩니다.

Ubuntu 17.10에서 18.04로 업그레이드하면 Textstudio/Qt가 중단됩니다.

17.10에서 18.04로 dist 업그레이드를 수행한 후 texstudio가 더 이상 실행되지 않습니다. 다음 오류가 발생합니다.

This application failed to start because it could not find or load the Qt platform plugin "xcb"
in "".

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, xcb.

Reinstalling the application may fix this problem.
Aborted (core dumped)

오류의 첫 번째 줄 끝에 있는 경로가 ""이기 때문에 문제가 texstudio 구성에 있는 것으로 의심됩니다.

내가 달리면 ldd /usr/bin/texstudio얻을 것이다

qtchooser -print-env

QTLIBDIR="/usr/lib/x86_64-linux-gnu"

내용 /usr/lib/x86_64-linux-gnu/qtchooser은

lrwxrwxrwx   1 root root     50 Dec 22  2017 4.conf -> ../../../share/qtchooser/qt4-x86_64-linux-gnu.conf

따라서 qt의 기본값은 qt4인 것 같지만 texstudio에는 qt5가 필요합니다. 그래서 ln -s qt5.conf default.conf/usr/lib/x86_64-linux-gnu/qtchooser에서 실행하면 이제 qtchooser -print-env인쇄됩니다.

QT_SELECT="default"
QTTOOLDIR="/usr/lib/qt5/bin"
QTLIBDIR="/usr/lib/x86_64-linux-gnu"

그러나 이것은 문제를 해결하지 못합니다. Textstudio가 여전히 시작되지 않고 동일한 오류 메시지가 인쇄됩니다.
