Hello, I use Fedora Silverblue 36, i would like to install K3b ou Brasero to burn audio CDs but i can’t them in the Flathub anymore.
Where did yhey go ?
Is there another alternative ?
Thanks.
K3b and brasero
Unfortunately, I can’t find it in the software library, so I installed it in Toolbox.
See Add org.kde.k3b by Mailaender · Pull Request #4395 · flathub/flathub · GitHub although we are kinda stuck.
There appears to be a permission problem in Flatpak. Even if you escalate to the max like this
--filesystem=/dev/sr0:rw
--device=all
--filesystem=host
--allow=devel
--socket=session-bus
it fails to run the DVD burning CLI tools inside the sandbox.
Install Brasero on Linux | Flathub is now here.
I’m not sure why you even try that. --device=all do expose all the /dev. As outlined in the PR review.
Because the documentation is not clear about it saying that /dev is reserved and can never be exposed. If you tried the application, then you will notice that the command line tools fail to access the drive. It smells like a sandbox issue. It would be helpful if Flatpak had something like Snap’s classic mode, where there is no sandbox confinement for situations like this, where it only causes problems.
The documentation is clear that --device=all give access to all devices. If you get a permission error, it’s because it can find the device but doesn’t have permissions to access. It feel complicated as a concept, but it has been like that for at least the last 30 years (aka as long as I have been using a UNIX like system). Otherwise it would say it can’t find the device if the device node didn’t exist due to a too narrow --device= permission.
Also I will point out that /dev/sr0 isn’t even proper, because there could be more than one.
