Description Henning 2023-09-05 20:35:08 UTC

I have a USB stick mounted on my system.

I select it as target in Iso Image Writer Flatpak and want to start writing.

Instead of unmounting and writing I get the said error.

What instead?
Unmount the USB Stick and proceed normally, everything works as expected.

Specified App:
ISO Image Writer	org.kde.isoimagewriter	1.0.0	stable	flathub	system

I can confirm this on KDE Neon.

If you run ISO Image Writer and follow the prompts using an already-mounted USB stick, it fails.

You must first unmount the stick, but the app never gives any hint that this is necessary.
