Beginne damit, die fehlende Eingabeaufforderung nach der Eingabe eines Leerzeichens in der q CLI unter Ubuntu 25.04 mit Bash und GNOME Terminal zu reproduzieren, und führe anschließend wie berichtet q doctor und q restart aus. Als erledigt gilt die Aufgabe, wenn die Eingabeaufforderungsvorschläge nach der gemeldeten Interaktion zuverlässig erscheinen und ein Regressionstest oder eine dokumentierte Überprüfung für die betroffene Umgebung vorhanden ist.
