Not a Linux dev, a Kapitano dev.

Quitting over that mild ass comment is a bit of an overreaction but its a hobby project so they can do whatever is best for them.

I wonder if Codeberg has proper moderation tools. That's a clear case of "ban the troll and move on".

I totally get how uncalled-for, unjustified negative comments and interactions can be demoralizing.

It's unfortunate how much impact bad actors have. It needs just one malicious actor to ruin something.

Can Flatpak itself be sunset with some bullying?

...why?

[-] ISO@lemmy.zip -3 points 4 months ago

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).

Shouldn't be a problem for you then right? 😄

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.
