How to fix Ubuntu 24.04.1?
Firstly, run the command sudo apt -f install to fix broken packages.
The .deb file for balena etcher is still incompatible with Ubuntu 24.04 because its dependencies were not updated.
If you need to use etcher, use its appimage from GitHub releases instead. Here is the download link for v1.19.21
However, many such electron apps are not working with Ubuntu 24.04 due to changes in apparmor. See How to permanently disable Ubuntu's new AppArmor user namespace creation restrictions? for how to fix.
