  • You are in a thread where a user is having a problem because of the push for flatpaks, and because of some distros like Fedora crippling their packages and providing objectively worse alternatives on purpose (because they don’t want to risk RH IBM getting sued). If the user was using some sane community distro like Arch, the user would have never come to realize that such unnecessary issues even exist.

    As for flatpak hate specifically, see my ramblings here.




  • This is such a excellent unexpected original comeback, I will give you a chance to do another one.

    How to extract the content of a flatpak

    Which is something you presumably want to do because you don’t want to use flatpak/ostree.

    The first step of course, is to install ostree. 🤨

    Then, via this very official method:

    ostree init --repo=repo --mode=bare-user
    ostree static-delta apply-offline --repo=repo some.flatpak
    ostree checkout --repo=repo -U $(basename $(echo repo/objects/*/*.commit | cut -d/ -f3- --output-delimiter= ) .commit) outdir
    

    This official solution looks very reliable.

    The impenetrable building blocks

    Searching vulnerability databases will obviously prove futile. Like the below sample entries (search limited to CVSS>=9.0 and Age<90d)

    libxml2 and sqlite are in the dependency tree of ostree itself of course. But really, nothing to see here.


  • Just the common “hate” talking points.

    Because it’s more inconvenience than help for users who are average or above, and have no interest in using that technology.

    If app developers start distributing binaries as flatpaks exclusively (examples of this already exist), then just extracting those binary packages alone is a chore (involving obscure(ish) steps starting with creating an empty ostree). It’s the kind of knowledge that is so useless you immediately erase it from your memory, which is what I did.

    Also, one look at the dependency tree of flatpak, or even just ostree, and you quickly realize how much of a joke the “security” claims are with all that attack surface (think the xz in systemd drama and multiply it by a 100).
