When installing many packages with Pacman (through Octopi), I get the following error message:
Installing selected packages...
QApplication: invalid style override 'gtk' passed, ignoring it. Available styles: Breeze, bb10dark, bb10bright, kvantum-dark, kvantum, cleanlooks, gtk2, cde, motif, plastique, qt5ct-style, Oxygen, QtCurve, Windows, Fusion
octopi-helper[aborted]: Suspicious execution method
Command finished with errors!
It seems to be more a warning than an error, anyway it does not let me install the corresponding package.
I use KDE/Qt, but I have most of GTK installed.
I looked for a "octopi-helper" package to reinstall it, but could not find it.
What else can I try?
