All but one of them have tor installed. Only four of them use the tpo repository (those provide either public or private network relays or dirauths). The others use regular debian-provided packages. > ** (Not least, I believe that the crypto in anything older than 0.2.7.* > will be a lot slower?) This doesn't matter unless you run a high-performance relay. Also, I think going from 0.2.7.x to 0.2.8.x increased my cpu usage on my busy relay. > * So I believe that you are probably not running 0.2.5 because you are > skilled enough to use backports or roll your own. I consider myself skilled enough, but I'd rather keep the amount of custom repositories to the bare minimum. Especially my more trusted computers don't get additional repos if I can help it at all. > Now, for contrast, consider Tor Browser Bundle: > > * TBB is designed for use by "normal people". > > * It is not running 0.2.5.* either, because it would be foolish to push out > such "old code" to the clients. > > * TBB runs code which we might call "Tor Stable", being probably a similar > version to the code which you yourself would deploy for a relay. > > * Therefore: "Debian Stable" is not offering "Tor Stable", instead it is > offering "Tor Stale", or "Tor Stagnant". > > > == Summary == > > Debian Stable, by default, offers code that we would deprecate on the > servers, and would never ship on the clients. Well, we're not currently deprecating it. It's still recommended by the dirauths to run one of those versions. I am not sure, but I think the main reason to ship recent Tors in TB is because we have to ship new Firefox releases anyway, so the pain of adding in some more software is minimal. That and the increased benefit of new security features, better blocking resistance, etc. > How is this to anyone's benefit? > > It's like the old chef's rule about "never cook with wine that you would > not drink by yourself" > > > == Challenge == > > Consider schools.

I'm a sysadmin at my school for a student computer pool, we have around 13k users and around 250 physical machines for students to use. The biggest thing I'd wish for were a system-wide installable Tor Browser that we can keep updated for our users. And we would do it, just like we keep everything else updated (for that job, while we do run debian stable, we're constantly chasing down last versions for a variety of software where the latest version is necessary for teaching or because it was requested by some students). > Consider people who don't know what "vim" does. :-) > > These are people who can use Tor for good purposes, and I believe that Tor > should seek to "enable" them, and make Tor easier to use for them. > > But the Tor code which comes with Debian, and thus with Raspbian, and > kinda-with-Ubuntu, is (by the metaphor) bad wine which you would never > offer to these people to actually drink nor cook with. In my world, these people don't really use apt-get, they will look to install something they can download from a website while following some instructions. TB seems to fit for that mental model. I just see a kind of disconnect between the hapless user and the advanced usecases where TB is not enough. If the user does know apt-get, they could install the torbrowser-launcher package on debian stable, which helps get them a shiny new TB. Admittedly, I have no idea about availability on Ubuntu. > In my previous e-mail I suggested removing Tor from Debian precisely > because of this future-staleness problem. I find this to be totally the wrong thing. We all want all our users to run our latest code, nownownow. It's a completely understandable line of thought, after all we're developers and passionately implemented features, created better architecture, debugged and fixed bugs for days. I think it's still kind of arrogant/presumptuous. As long as there are no reasons to kill an older version (like security issues, incompatability with a newer protocol where the cost of keeping to support the older version is significant, etc) I don't think we should break compatibility. > I still believe that this is a decent idea, because stale code sucks. > > Another possible solution would be creation of a "Tor Server Bundle" - > designed and maintained to run successfully on most major platforms, it > would be a bunch of scripts that find existing, stale versions of Tor, kill > and remove them, and migrate the platform to a more recent version, with > *optional* enabling of auto-updating because you will want to have a stable > environment. :-P I don't think these would be accepted under Debian's policies, at least I would find a package that did this without very clearly labelling what's going on to be unacceptable. Note the point above about breaking changes or new major security features that require work to get right. > And it would (ideally) also ship with some portable, stupid but bombproof, > interactive and scriptable CLI wizards for setting up Onion services. Do you really want onion service creation to be something that isn't done automatically for you like in Ricochet, but rather something a user has a tool to do manually?

I agree that as a developer, I always want everyone to use the latest version of all my stuff. As a user of a lot more software than that which I develop myself, I really don't agree.
