ZeroTier isn't installed!

[Youhaojen]

First, I would like to thank you for the great project! I try to install the ZeroTier-GUI on ubuntu 20.04 and make sure the GLIBC version and python version which the ZeroTier-GUI required. Unfortunately, it showed "ZeroTier isn't installed!". Do I need to install other plug-ins? Thx

Yes, you do need to have ZeroTier itself up and running. This is just a front-end after all, ZeroTier doesn't come with it. Good news are that if you're seeing that window, then it means the program works, you just need to have ZeroTier :)

I have installed this on a machine a few months ago and now I can't seem to get it working. Following your new guide, I get this: (Reading database ... 213663 files and directories currently installed.) Preparing to unpack .../ZeroTier-GUI.deb ... Unpacking zerotier-gui (1.2.1.r.) ... dpkg: error processing archive /home/ltn-vpe/Downloads/ZeroTier-GUI-master/ZeroTier-GUI.deb (--install): trying to overwrite directory '/usr/share/applications' in package kio 5.80.1-0ubuntu3 with nondirectory Processing triggers for mailcap (3.68ubuntu1) ...

You don't have the /usr/share/applications directory? What distro do you use?

[stevespaw]

Brand new install of Ubuntu 21.04 from the main site

[tralph3]

Ok, but do you have that directory?

[stevespaw]

I will look in the morning and get back to you . Thanks

[stevespaw]

yes I do:

[tralph3]

Could you upload the resultant .deb file here please?

[stevespaw]

ZeroTier-GUI.zip

[tralph3]

Thanks, I'll check it out when I get home.

[tralph3]

Ok I think it's fixed. Do a git pull and run the script again, then try to install it.

[stevespaw]

A little better but no go - See attached ZeroTier-GUI-master.zip ZerotierGUI.txt

Well, the deb package was created properly this time. If clicking the icon does nothing, then launch it from terminal with zerotier-gui and see what you get. I recommend however to completely delete the program and reinstall it with the deb package. Don't worry, the program doesn't have any configuration, all the networks and stuff gets picked up from zerotier-one directly, reinstalling won't make you lose anything. Primarily, delete the executable in /usr/bin and delete the .dektop file in /usr/share/applications, then reinstall and reboot the system to make Ubuntu read the "new" .desktop file, see if that does it.

[stevespaw]

Ok well: sudo zerotier-gui - works, but launching from the icon does not. I tried all of the uninstall and delete and re-install - reboot.

[stevespaw]

I do get this when launching from terminal:

if this matters

[tralph3]

Yes that last error is harmless. You can see the program is still running, it didn't exit because of it. That appears because to display the error message about ZeroTier not being installed I need to create a proper window. So I create a window and instantly make it dissapear so you only see the error message. When I create the actual window, I destroy the first one and this pops up, but it's harmless.

If launching with the terminal works, then the problem is with the .desktop file. Paste the contents of /usr/share/applications/zerotier-gui.desktop.

[stevespaw]

[Desktop Entry] Encoding=UTF-8 Exec=/usr/bin/zerotier-gui Icon=zerotier-gui Type=Application Terminal=false Comment=Linux front-end for ZeroTier Name=ZeroTier GUI GenericName=ZeroTier GUI StartupNotify=false Categories=Utility; Version=1.2.2

[tralph3]

Hmm and you do have the /usr/bin/zerotier-gui executable right? Can you try running zerotier-gui in a terminal WITHOUT sudo? If that works, then I have no clue why desktop file doesn't.

[stevespaw]

it does NOT run without sudo

[tralph3]

Ahh so we're getting somewhere. Do you get some error?

[stevespaw]

$ zerotier-gui zerotier-cli: authtoken.secret not found or readable in /var/lib/zerotier-one (try again as root) Traceback (most recent call last): File "/usr/bin/zerotier-gui", line 864, in mainWindow = MainWindow().window File "/usr/bin/zerotier-gui", line 121, in init self.refresh_networks() File "/usr/bin/zerotier-gui", line 221, in refresh_networks networkData = self.get_networks_info() File "/usr/bin/zerotier-gui", line 257, in get_networks_info return loads(check_output(['zerotier-cli', '-j', 'listnetworks'])) File "/usr/lib/python3.9/subprocess.py", line 424, in check_output return run(*popenargs, stdout=PIPE, timeout=timeout, check=True, File "/usr/lib/python3.9/subprocess.py", line 528, in run raise CalledProcessError(retcode, process.args, subprocess.CalledProcessError: Command '['zerotier-cli', '-j', 'listnetworks']' returned non-zero exit status 2.

[tralph3]

Ok... the problem was that I was checking if the error string contained a certain substring. This is very obviously a bad way of doing things, because then something like this can happen. Apparently ZeroTier changed the error string, and now my program doesn't work because of it. I changed it so it checks for error codes now, and this hopefully means its fixed.

Digging through the code was painful, I'll have to do some major rewrites... some time. Anyways, download the latest version and repackage it, should work now.

[stevespaw]

Ok it works now - with some message boxes. But all OK! Thanks for this project.............
