Как исправить ошибку Tor 404

Оценка «Tor 404 Error»

Как правило, практикующие ПК и сотрудники службы поддержки знают «Tor 404 Error» как форму «ошибки во время выполнения». Разработчики программного обеспечения, такие как SoftwareDeveloper, обычно работают через несколько этапов отладки, чтобы предотвратить и исправить ошибки, обнаруженные в конечном продукте до выпуска программного обеспечения для общественности. Поскольку разработчики программного обеспечения пытаются предотвратить это, некоторые незначительные ошибки, такие как ошибка 404, возможно, не были найдены на этом этапе.

Некоторые пользователи могут столкнуться с сообщением «Tor 404 Error» при использовании Tor. Сообщение об этой ошибке 404 позволит разработчикам обновить свое приложение и исправить любые ошибки, которые могут вызвать его. Затем Tor Project может исправить эти ошибки в исходном коде и подготовить обновление для загрузки. Поэтому, когда вы сталкиваетесь с запросом на обновление Tor, это обычно связано с тем, что это решение для исправления ошибки 404 и других ошибок.

Что вызывает ошибку времени выполнения 404?

Наиболее распространенные вхождения «Tor 404 Error» проблемы при загрузке Tor. Вот три наиболее распространенные причины, по которым происходят ошибки во время выполнения ошибки 404:

Ошибка 404 Crash — программа обнаружила ошибку 404 из-за указанной задачи и завершила работу программы. Эти ошибки обычно возникают, когда входы Tor не могут быть правильно обработаны, или они смущены тем, что должно быть выведено.

«Tor 404 Error» Утечка памяти — Ошибка 404 утечка памяти происходит и предоставляет Tor в качестве виновника, перетаскивая производительность вашего ПК. Это может быть вызвано неправильной конфигурацией программного обеспечения Tor Project или когда одна команда запускает цикл, который не может быть завершен.

Ошибка 404 Logic Error — логическая ошибка возникает, когда компьютер производит неправильный вывод, даже если вход правильный. Он материализуется, когда исходный код Tor Project ошибочен из-за неисправного дизайна.

В большинстве случаев проблемы с файлами Tor 404 Error связаны с отсутствием или повреждением файла связанного Tor вредоносным ПО или вирусом. Для устранения неполадок, связанных с файлом Tor Project, большинство профессионалов ПК заменят файл на соответствующую версию. Запуск сканирования реестра после замены файла, из-за которого возникает проблема, позволит очистить все недействительные файлы Tor 404 Error, расширения файлов или другие ссылки на файлы, которые могли быть повреждены в результате заражения вредоносным ПО.

tor-browser-bundle-bin: download error #108954

Describe the bug
The download for tor-browser-bundle-bin fails with a 404 error.

To Reproduce
Steps to reproduce the behavior:

Expected behavior
Tor installs

Additional context

Metadata
Please run nix-shell -p nix-info —run «nix-info -m» and paste the result.

• system: «x86_64-linux»
• host os: Linux 5.4.87, NixOS, 21.03.20210107.f211631 (Okapi)
• multi-user?: yes
• sandbox: yes
• version: nix-env (Nix) 2.4pre20201205_a5d85d0
• channels(root): «nixos-21.03pre257339.83cbad92d73»
• channels(pinpox): «home-manager»
• nixpkgs: /nix/var/nix/profiles/per-user/root/channels/nixos

The text was updated successfully, but these errors were encountered:

Can you update your channel please? 83cbad9 is 5 weeks old and as a result, TBB 10.0.5 is out-of-date. This should be fixed in e924c5d.

Likely duplicate of #107141.

Huh, that’s strange. I just did:

Is that not enought to update a flake-enabled system config?

@pinpox are you using nixflk?

EDIT: nvm, I found your https://github.com/pinpox/nixos. If you don’t mind we can go discuss the out-of-date channel thing there, and keep this thread about whether there’s something wrong with tor-browser-bundle-bin. (most likely not but we’ll confirm)

can you try nix shell nixpkgs#tor-browser-bundle-bin real quick? I’ll help you out with the legacy commands right after.

@lourkeur Sorry, I just ran:

and now it builds fine with nix-shell -p pkgs.tor-browser-bundle-bin . But I’m a quite confused, I thought updating channels was nothing I should be doing at all with flakes?

nix shell nixpkgs#tor-browser-bundle-bin also works, btw.

and now it builds fine with nix shell nixpkgs#tor-browser-bundle-bin . But I’m a quite confused, I thought updating channels was nothing I should be doing at all with flakes?

The general advice is more along the line of not mixing flakes and channels if possible. In your case what happens is your $NIX_PATH probably contains a reference to /nix/var/nix/profiles/per-user/root/channels/nixos , which is an out-of-date channel (installed by default because flakes are still experimental). What I do and what you might want to do is nuke root’s channels, and set nix.nixPath = [ «nixpkgs=$» ] to keep hyphenated commands up-to-date and happy during the transition period. (example)

@lourkeur Huge thanks, that works. For reference in case anyone finds this:

I removed the nixos channel for root and for my user

Then added to the configuration of all my machines

After rebuilding the configuration (or deploying) I had to logout and in again for $NIX_PATH to be set. It is now

for my user: /home/pinpox/.nix-defexpr/channels:nixpkgs=/nix/store/02bj12ja21vibib3c1k065568x1d17ds-source
for root: /root/.nix-defexpr/channels:nixpkgs=/nix/store/02bj12ja21vibib3c1k065568x1d17ds-source

and I can run commands like nix-shell -p pkgs.tor-browser-bundle-bin without problems on both accounts. The only issue I still have, is that after rebuilding/rebooting the nixos channel seems to «reappear» in nix-channel —list . Does it get added automatically?

sos: 404 download error #663

hi, I try TOR on Kali Linux and Parrot OS but said: error 404
I try on terminal command sudo … same error. any suggest.
many thanks and a hug for all best community

The text was updated successfully, but these errors were encountered:

FOR THE NEW INSTALLATION (not an update)
basically, follow this
build from source
however, you just have to change the first command here to
git clone https://github.com/tensornova/torbrowser-launcher.git

tell me if there is an error related to ‘float’ when you follow this.

FOR THE NEW INSTALLATION (not an update)
then
(1) delete a directory torbrowser-launcher you downloaded before via git clone https://github.com/tensornova/torbrowser-launcher.git

(2) follow build from source
but try git clone -b hotfix —single-branch https://github.com/tensornova/torbrowser-launcher.git
instead of the first command

hi, sorry for the long wait i was asleep

the software starts, but its stuck at 0% at downloading signatures

Edit: nvm it works, thanks

EDIT 2: it deleted all of my data! 🙁

Hi,
I have the same problem, do you know a way to make it work with flatpak?
Do I just need to wait for the flatpak to be updated?
Thanks you

Hi, I have the same problem, do you know a way to make it work with flatpak? Do I just need to wait for the flatpak to be updated? Thanks you

That’s exact. First we need to have it being merged via #661, and then, that a new build is pushed to flatpak.

then (1) if you’ve already installed it, please uninstall it or delete a directory torbrowser-launcher you downloaded before

(2) follow build from source but try git clone -b hotfix —single-branch https://github.com/tensornova/torbrowser-launcher.git instead of the first command

Hey none of this worked for me at all. Take a look. I’m on Ubuntu 22.04. When will TOR be fixed?

I am also getting the «Download Error: 404»

When is this going to get fixed?

hi, sorry for the long wait i was asleep

the software starts, but its stuck at 0% at downloading signatures

Edit: nvm it works, thanks

EDIT 2: it deleted all of my data! 🙁

um, sorry, I didnt considering update that is not a new installation. It’s a guess, but it seems that the data has been deleted because a path to the data has changed even though the data exists. I’ll check it out and let you know if I can. and i recommend a downgrade if you are able to do it

thats reassuring, BTW what was the old location of the browser profile, maybe I can recover it manually?

I failed with torbrowser-launcher from Debian Stable too.
I think an update should be released through OS distributions.

it will slowly happen, just wait for it slowly

also Debian Stable will take a pretty long time to upate torbrowser-laucher so i think the bestthing to do rn is to install it maually

This is no solution, but info towards one.

Tor seems tor has moved to a universal language package in 12.0.1.

So the launcher should not use the language to composite the download path, instead it should use «ALL».

open the /usr/lib/python3/dist-packages/torbrowser_launcher/common.py file

Change the discover_arch_lang function to simply set self.language to «ALL», i.e. delete all the complicated language guessing code that is there and replace it with one line (I also show the comment of the next function, so it becomes clear how far it has to be replaced):

Now it downloads alright and tries to install . where it hangs.

Some sort of unfulfilled promise or whatever the contraption is called in Python.

So back to square one.

Okay, I’ve done this step as a workaround for an installation:

After this, on launching torbrowser-launcher it downloads successfully application’s package, but it breaks with:

Then, to complete workaround at user profile this must be run in a terminal:

And it just works.
All this expecting torbrowser-launcher incorporates new fixes.

Watching this issue also (flatpak install didn’t work for me either — flathub not recognized or something like that)

when using flatpak i get this error:

qt.qpa.xcb: could not connect to display
qt.qpa.plugin: Could not load the Qt platform plugin «xcb» in «» even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.
Available platform plugins are: eglfs, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, xcb.

i tried to use source and debian repository but i got error 404. also when i try tensornova’s solution it requires my github username and password and then says that password authentication has been ended since august 2021.

also when i try tensornova’s solution it requires my github username and password and then says that password authentication has been ended since august 2021.

You have to generate a token and use that as your password. Either way, when you do that you are (or I was) notified that the repository doesn’t exist

i tried to use source and debian repository but i got error 404. also when i try tensornova’s solution it requires my github username and password and then says that password authentication has been ended since august 2021.

My workaround also works with Debian packaging source (first part to common.py , next part to postinst & skel)

Nevertheless to say I have the same issue. Commenting just for the record:
OS: Kali Linux (latest upgrade)
Downloaded: by using official kali’s repo sudo apt install torbrowser-launcher .

I hope they will make a fix soon

I’m on Ubuntu 22.04, latest update. Installed the torbrowser-launcher from the official repo.

Doing this changes should make the torbrowser-launcher works as expected. But before you do, you must remove this directories ~/.cache/torbrowser, ~/.local/share/torbrowser, ~/.config/torbrowser as they save information for the launcher and the fix won’t work using those.

Be aware that if you have a working Tor Browser installation, you will lose your settings and working installations. Using this fix for the torbrowser-launcher doesn’t take into account existing installations, but gives an idea on why the launcher fails to download the current version.

First change this line on /usr/lib/python3/dist-packages/torbrowser_launcher/common.py on line 171, you will need root access to make changes to this file:

if hasattr(self, 'settings') and self.settings['force_en-US']:
    language = 'en-US'
else:
    #language = self.language
    language = "ALL"

Commented out the variable language and set it again with the value "ALL", that way the launcher will look for the correct signatures and tarballs files in the mirror.

Also made a change in line 277 of the same file, this time when setting up the variables to the install location, the launcher will refer to the language setting and set it as part of the directory installation, but the actual package downloaded by the launcher will refer to the directory as tor-browser and not by tor-browser_ALL as the launcher would expect it to do:

"tbb": {
    "changelog": tbb_local
    + "/tbb/"
    + self.architecture
    + "/tor-browser"
    #+ "/tor-browser_"
    #+ language
    + "/Browser/TorBrowser/Docs/ChangeLog.txt",
    "dir": tbb_local + "/tbb/" + self.architecture,
    "dir_tbb": tbb_local
    + "/tbb/"
    + self.architecture
    + "/tor-browser",
    #+ "/tor-browser_"
    #+ language,
    "start": tbb_local
    + "/tbb/"
    + self.architecture
    + "/tor-browser"
    #+ "/tor-browser_"
    #+ language
    + "/start-tor-browser.desktop",
},

Here there are three entries that must be changed. All of them refers to /tor-browser_ + language as part of the installation directory. It must be changed to /tor-browser and attention on the second entry as it must end with ,.

This fix is terrible, it doesn’t remove the language setting at all, just fixes it in order to make it work with what is available in the mirror. I guess we need to wait for the devs to make this fix on the repo package, by that time those changes will be rewritten and hopefully still works.

Hope this helps.

I’ve written a question on AskUbuntu.com about this:

I use torbrowser-launcher (package version 0.2.0-2 from the Wily/universe amd64 repository on Ubuntu 15.10) which runs Tor Browser 5.0.4.

Since today, after the update to 5.5a4-hardened became available, torbrowser-launcher does not start the browser any more but tries to update itself. This however fails due to a Download error: 404 Not Found as you can see in the two screenshots below. If I click Yes when it asks to switch to the default mirror, that doesn’t change anything. Still the same error. And on the next try, it will still complain about a non-default mirror.

When I run torbrowser-launcher in a terminal, I get this:

If I open the Tor Browser Settings from terminal torbrowser-launcher --settings, select a different mirror and to «search for updates on next launch», then click on Launch TorBrowser, I get the following dialogue and terminal output (first answering Start, second time answering Exit):

What is wrong here and how can it be fixed?

Probably related to issue #206

I’ve written a question on AskUbuntu.com about this:

I use torbrowser-launcher (package version 0.2.0-2 from the Wily/universe amd64 repository on Ubuntu 15.10) which runs Tor Browser 5.0.4.

Since today, after the update to 5.5a4-hardened became available, torbrowser-launcher does not start the browser any more but tries to update itself. This however fails due to a Download error: 404 Not Found as you can see in the two screenshots below. If I click Yes when it asks to switch to the default mirror, that doesn’t change anything. Still the same error. And on the next try, it will still complain about a non-default mirror.

When I run torbrowser-launcher in a terminal, I get this:
