Tor 0.4.25 release how can we upgrade

New tor blog post when can we expect a whonix upgrade to this version of tor? Is it possible and safe to upgrade manually there is some major bug fixes in this release.

Looks like it could be from source only is it possible to do that on whonix, any tutorials? Do we need to do anything specific to the old version installed?

Cloned my gateway for testing

downloaded 0.4.2.5 and cd into it

had to install libevent-dev, libssl-dev and zlib1g-dev

ran ./configure and make followed by sudo make install

Then ran tor --verify-config

response 0.4.2.5 with a notice configuration file /usr/local/etc/tor/torrc not present using reasonable defaults

ran whonixcheck and it gives the following error.

tor exit code 1

When deb packages are available from https://deb.torproject.org, I will download them from there and upload to Whonix developers repository from which they will flow to other suites as per usual.

Nothing Whonix specific regarding installation from source. As per:

Thanks Pat I know you work hard for this project.

I am trying to install this new version to test it out a few very quick questions do I need to uninstall the old tor version first? I have manged to install the newest and verify finds it but produces the error above and whonixcheck won’t run.

Do I need to modify any files to point tor in the direction of the torrc file?

Thank you.

Updated https://www.whonix.org/wiki/Tor_Versioning#Newer_Tor_Versions:_The_Tor_Project_Repository just now. I was looking if we can find a suite there which has this version.

https://deb.torproject.org/torproject.org/dists/tor-experimental-0.4.2.x-buster/ currently has Quote https://deb.torproject.org/torproject.org/dists/tor-experimental-0.4.2.x-buster/main/binary-amd64/Packages

Package: tor
Version: 0.4.2.4-rc-1~d10.buster+1

Even https://packages.debian.org/experimental/tor has only 0.4.2.4-rc-1.

If you update a deb package there is usually no need to remove the existing deb. Debian’s dpkg/apt will handle this.

I don’t think so. Configuration file stays untouched. Otherwise apt would ask about it during upgrades.


Since there is no deb yet… The question is…

  • On Debian buster.
  • Existing Tor deb package installed.
  • AppArmor enabled.

How to upgrade tor from source code?

Since it’s not the Debian package I see potential causes for breakage:

  • different file paths
  • systemd unit file vs no systemd unit file (might lack that systemd hardening (seccomp))
  • apparmor (might lack that)

Really non-trivial. I don’t think anyone documented that ever.

“Really” removing the Debian tor pacakge is hard. Due to technical limitations described here:

A hack to uninstall tor:

sudo dpkg --force-all --remove tor

More information cloned the workstation and installed from source and it worked on the workstation kinda of everything installed and my test forum hidden service was reachable. The only issue was when I ran whonixcheck it could not tell if anything needed updating and when I manually ran the update commands it said there was a key mismatch.

In the gateway I had to turn whonixcheck off.

Workstation doesn’t run Tor. Shouldn’t run Tor.
(https://www.whonix.org/wiki/Dev/anon-ws-disable-stacked-tor)
Only Tor Browser.

Unrelated whonix.org server issue which is now fixed.

Thanks Patrick it’s time I deleted the cloned workstation and gateway and wait until whonix releases this tor version.

One final question if I may Patrick on average how long does it take the whonix team to add a new tor release once the packages have been added by the tor project.

How to install Tor from source code is now documented here:

sys-whonix doesn’t seem to like Tor 4.2.5. Upon launch of sys-whonix you get this error:

ERROR: Tor Pid Check Result:

Restarting of Tor doesn’t fix the problem.

Reload Tor with sudo service tor@default restart

Check status -> same error as above.

So I guess something is wrong with tor-service-defaults-torrc with this new version? Tor v4.1.6 works perfectly…

Any idea?

I can’t reproduce this.

tor 0.4.2.5-1~d10.buster+1 is now in Whonix testers repository.

Easy to replicate - it is caused by Sandbox 1 in the tor config file.

Remove that -> 4.2.5 works
Don’t remove it -> Tor consistently fails to start

Maybe it is yet another sandbox bug in Tor code (?) e.g. previous ones:

https://trac.torproject.org/projects/tor/ticket/18397
https://trac.torproject.org/projects/tor/ticket/25677
https://bugs.torproject.org/22516

Maybe nobody is running the sandbox much in Qubes-Whonix or those doing testing, but I doubt it.

Very possible.

Also very possible.
