No, they are not. Neither Fedora nor Debian have any sandboxing and if you add a third-party repository, it gets root access to your system and can run any scripts when installing or updating software.

Also what I meant is a "standard execution environment", so that the developer doesn't need to make a separate version for each Linux distribution, and doesn't have to make repositories.

sorry, i misread that. i thought you were just talking about the trust and vetting issue. i glanced over "sandboxing". sandboxing apps is what android is doing and i think nixos and also flatpack, etc. and with flatpack, that approach is effectively already possible, and in a way, already in the works. but it's a different approach, one that i don't like at all, because it is way to heavy handed and makes interoperability between apps very difficult. it also doesn't solve the trust problem, because at the end of the day the sandboxed app still needs access to my data, so i still need to trust it.

however that is completely besides the point because we are really talking about improving trust with pypi and npm and the like. sandboxing here is simply not possible because these are mostly libraries to be used for development of larger apps.

the approach distributions are using now would be useful here.
