Question

Balena Etcher is not opening in Ubuntu 24.04. How to run it? I am using the appimage. Other appimages are not working either.

Due to recent changes in apparmor, none of the electron apps (except VS Code) work out of the box in Ubuntu 24.04.

Temporary solution: The workaround is to run the following command.

sudo sysctl -w kernel.apparmor_restrict_unprivileged_userns=0

It has to be run again after rebooting.

To make it permanent, run the command

echo 'kernel.apparmor_restrict_unprivileged_userns = 0' | 
  sudo tee /etc/sysctl.d/20-apparmor-donotrestrict.conf

Note: Disabling the apparmor restrictions in 24.04 does not make it more vulnerable than 22.04. Please read this for more details, and use it at your own risk.

Thanks for helping out! According to https://discourse.ubuntu.com/t/noble-numbat-release-notes/39890#security-improvements-14, I believe using an AppArmor profile would be a better solution but I don’t know how to create one for Etcher’s AppImage release. Would you happen to know how? – sunknudsen May 03 '24 at 12:15
Unfortunately there is no way to create an apparmor profile for etcher as far as I know. – Archisman Panigrahi May 03 '24 at 12:47
