I had the same bug. The problem appeared after a kernel update. It happens because there is no kernel module TUN. This can be checked with the following command:

$ sudo dmesg | grep TUN
[   26.091113] tun: Universal TUN/TAP device driver, 1.6

Outline needs to create a TUN interface to work properly.

$ route -n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
0.0.0.0         192.168.31.1    0.0.0.0         UG    304    0        0 wlan0
10.0.85.0       0.0.0.0         255.255.255.0   U     0      0        0 outline-tun0
192.168.31.0    0.0.0.0         255.255.255.0   U     0      0        0 wlan0

If you don’t get this output, simply reboot and check again.

If it is still missing, add a TUN kernel module and reboot.

sudo modprobe tun
lsmod | grep tun
reboot

I hope it helps.

As a workaround you can recompile the client locally. I’ve just tried it and it’s working just fine on Ubuntu 22.04

Clone the repo:

git clone git@github.com:Jigsaw-Code/outline-client.git
cd outline-client

Install node 16 (for example using brew)
```
brew install node@16
```
Install all dependencies
```
npm install
```
Build the app
```
npm run action electron/build linux
```
Now you have properly working Outline-Client.AppImage and you can run it
```
./build/dist/Outline-Client.AppImage
```

I’m using the latest outline appimage on Debian 11 and 12

I start the app
Then I click on connect
The app asks for my root password
I enter the password and then the app says “Initializing Outline…Outline has been successfully initialized. please try again to conenct to the server” and that’s it… connecting again doesn’t seem to be working

The server is running on Debian 11. Windows and android apps work fine.

PS It looks you need to reboot your PC to make the app working… The devs should have specified it in the app description tbh…

I have the same issue in Ubuntu 22.04.
