Coldbrew is a “brew” style package manager for Linux distributions that offers the full power of the Alpine Linux aports repository with no root access required
Coldbrew is a bit of a mix of flatpak and homebrew. It uses a very lightweight sandbox (bubblewrap) mainly as a means of isolating dependencies. It aims to server a similar goal as homebrew, but without the PATH issues homebrew brings (see: https://invent.kde.org/kde-linux/kde-linux/-/merge_requests/408)
Example Usage:
coldbrew install neovim # install the package
coldbrew run nvim # run nvim
coldbrew wrap nvim # create a wrapper to type less
nvim # run nvim
So in other words, it fixes all of the shit that makes Flatpak broken and useless?
Rather, removes all the security elements, forcing you to risk your system because you never learned permissions.
In the sense that allowing a malicious application to steal your SSH keys is “fixing”, yes.
