I have a problem with Tor Browser installation .
I try to install it from app center but it does not work .
I am new to Budgie and probably do something wrong .
The thing is the browser has worked some time ago and suddenly has stopped .
I have been trying to install it back again and I can’t do that .
Maybe someone has some advice ?
Hi @MEDICU!
Impossible to say. I don’t use the AppCentre, I prefer to know what I’m doing.
The easiest way is to redo your installation on a different basis.
Type this line to find out what’s installed:
apt search torbrowser
Then this one, adapting the application name to the previous search result, to remove the installation:
sudo apt purge <application name>
Then copy and paste to reinstall:
sudo apt update && sudo apt install torbrowser-launcher
Launch “Tor Browser”, choose “Automatic connection” and click on the button to connect.
Then come back and tell us. 
Thank you for your reply and advise .
I am trying to do the steps you were kind to mention about …
I hope I have done it right what you advised .
I have opened Tilix and I write all you said over there .
On the end of the massage I got these :
E: The repository ‘Index of /torproject.org focal InRelease’ is not signed.
N: Updating from such a repository can’t be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration detai
All Budgie Ubuntu operating system have been installed on my computer by someone else few weeks ago and it is my first contact with Linux.
I start to learn how to work on this operation system so please have a patience .
However, I checked on Ubuntu Budgie 24.04. Everything was OK.
I have the impression that you are using an older version of Ubuntu Budgie.
Could you check?
lsb_release -a
Here’s what I suggest to get around this problem, which I can’t really explain to myself:
sudo apt purge torbrowser-launcher
dpkg -l flatpak gnome-software-plugin-flatpak
sudo apt update && sudo apt install flatpak gnome-software-plugin-flatpak
flatpak remote-add --if-not-existent flathub https://dl.flathub.org/repo/flathub.flatpakrepo
flatpak install flathub org.torproject.torbrowser-launcher
Thank you for your reply .
I’ve been updating system recently so I do not think it is a case .
I can see I have exactly the version you’ve mentioned : 24.04
You can see a screen shot of my Budgie version in attachment .
Please be aware In contradiction to your view I have an impression there is some other problem which appeared.This disturbs the installation not only of tor browser app .
I can see the same issue with another app : Privacy Browser available in the app center. The app is installed and I can see the icon of it but it is not opening .The same with Tor Browser .
All of these I do in Tilix right ?
I have Tilix emulator terminal : Tilix: A tiling terminal emulator
…and what I understand this kind of terminal is used to communicate with Budgie operating system , right ?
If so , then I will try to do what you suggest.
Since the error message was talking about “Focal” (the codename for UB 20.04), I assumed you were still using that version.
Shame on me! I didn’t specify to open the terminal (Tilix for UB 24.04), although I always specify the keyboard shortcut (Ctrl Alt t). 
But use the flatpak format, that should avoid these weird problems I can’t explain.
All the more reason to avoid AppCentre — or learn how to do it (it’s no more complicated than that). 
Hi,
it seems to me that apt points to a focal source, while - if I’ve correctly understood - you’re running a noble; maybe checking /etc/apt/sources.list.d (and/or /etc/apt/sources.list) to see if there’s something related both to focal and tor it could be useful.
[the reference to torproject.org suggests a custom source, like a PPA or something similar while tor, torbrowser-launcher and so on are in standard universe repo in 24.04]
(or maybe I haven’t understood anything and in such case my apologies 
)
Sil
Exactly, Sil!! That’s what I understood too, and I figured it was the remnant of a distant installation where we went through a PPA to install the latest versions of Tor Browser, that the upgrades hadn’t removed.
Thank you very much for you time and advises.
Appreciate that .
Here is an update of the situation:
In the mean time I had some help of my friend. I left my computer with him and he has installed the Tor browser .
Unfortunately I haven’t had opportunity to see how he installed that and I can not ask him about that for now .
However it seems to me that something is wrong with this installation .
The tor browser opens but I can see a massage :
This is a link mentioned in this massage :
and it opens at : Security features warning
Hi @MEDICU and thank you for your reply.
I always get this message.
But in order to do what it says, Firefox would have to be installed in the “/bin” directory of your personal space. You can check, but I doubt there is even a default “/bin” directory in it.
I’ve tried to do what the message says by changing the Firefox path to match my installation, but as expected, it doesn’t work,
As it also says, “some of Firefox’s security features may provide less protection on your current operating system”. This is a possibility, not a certainty.
Is it absolutely necessary to give in to this paranoia? Unless you’re planning to surf the dark net…
Click the “Don’t show again” button and be done with it.
Hi ,
I need to start back again .
The tor browser worked and suddenly disappear from the desktop apps. Similar like before.
I have tried again to install it from app depository but it does not work.
After I have installed it I see the icon of tor browser on the desktop screen but after a click does not open the app.
In this case I start to do what you have suggested :
[sudo] password for :
Reading package lists… Done
Building dependency tree… Done
Reading state information… Done
The following package was automatically installed and is no longer required:
python3-gpg
Use ‘sudo apt autoremove’ to remove it.
The following packages will be REMOVED:
torbrowser-launcher*
0 upgraded, 0 newly installed, 1 to remove and 10 not upgraded.
After this operation, 0 B of additional disk space will be used.
Do you want to continue? [Y/n]
after i wrote Y
I have got this :
(Reading database … 281818 files and directories currently installed.)
Purging configuration files for torbrowser-launcher (0.3.7-1ubuntu1) …
Here I have my system and computer name and is ready for me to write something which I do not know ?
The other thing is you have suggested to check if my system is ready to receive flatpak packages which I do not know how to check ?
To do so is it enough to type now this commend ? :
dpkg -l flatpak gnome-software-plugin-flatpak
If the question is directed at me, @MEDICU, I have tried everything I advised you to do before posting.
And yes, if this line:
dpkg -l flatpak gnome-software-plugin-flatpak
… returns these, no problem installing flatpak:
ii flatpak 1.14.6-1ubuntu0.1 amd64 Application Deployment Framework f>.
ii gnome-software-plugin-flatpak 46.0-1ubuntu2 amd64 Flatpak support for GNOME software`Preformatted text`
For Tor, copy and paste this line:
flatpak install flathub org.torproject.torbrowser-launcher
Thank you for your reply .
Please be aware I haven’t done anything yet from what you have been kind to suggesting . I just start to do that.
In the mean time I mean before I left my computer with my friend and he has installed Tor browser again but it looks like it did not helped . All of this is because I do not know yet how to install programs on Linux.
Anyway I just start what you have suggested myself.
Let me remind you that this is my first time to communicate with computer this way ,I mean via terminal in Linux … so basically when I do that I start also learn what all of these commands mean .
I have got this now :
Desired=Unknown/Install/Remove/Purge/Hold

ii gnome-software-plugin-flatpak 46.0-1ubuntu2 amd64 Flatpak support for GNOME Software
lines 1-7/7 (END)
I do not know what to do next ?
… probably I should start from your first suggestion from 01.Dec as it seems easier - less commends ?
I am sorry I haven’t seen it till now .
I understand, but as for me, I’m French and my English is pretty rusty.
I thought I’ve covered everything in my post.
All you have to do now is enter this line:
flatpak install flathub org.torproject.torbrowser-launcher
Sincerely.
English is not my parents language also .
I would never recognize you are not an native English speaker .
I think your English is very good .
I can not type anything anymore in terminal?
Computer in terminal has been doing something since my last commend and I got this now :
