error Error: User did not grant permission.

[jedfonner]

• Etcher version: 1.7.9
• Operating system and architecture: KDE Neon
• Image flashed: ubuntu-22.04-desktop-amd64.iso
• What do you think should have happened: It should have prompted me for admin elevation and then flashed the ISO to the USB drive
• What happened: Flashing won't start and the dev console shows error Error: User did not grant permission.
• Do you see any meaningful error information in the DevTools?

• Workaround

Running sudo /opt/balenaEtcher/balena-etcher-electron %U from the command line allows me to flash the image correctly but this should not be necessary.
