OutlineCLI: Failed to create tun device

[TyT-NICK]

Full error: failed to create tun device: failed to create TUN/TAP device: ioctl: device or resource busy

The issue occurs after stopping and starting the service again. I guess that it happens because of incorrect service stopping (just closing the terminal) but I didn't find any info about a correct way.

Hi @TyT-NICK , thanks for submitting the issue. Please use Ctrl+C to stop OutlineCLI properly, so that Outline CLI will be able to clean up the resources. Otherwise, a restart of the system would resolve the issue as well.

Thank you. It's work solution for me.

My system information:
uname -a
Linux fedora 6.6.9-200.fc39.x86_64 #1 SMP PREEMPT_DYNAMIC Mon Jan 1 20:05:54 UTC 2024 x86_64 GNU/Linux

Ctrl+C doesn't help for me. Terminal just sticks and the only way I found to close it after is to close the window. Restarting helps but it's really messy since I have to reconnect many times a day.

@TyT-NICK Hmm, that's weird because OutlineCLI will listen for three signals: https://github.com/Jigsaw-Code/outline-sdk/blob/main/x/examples/outline-cli/app_linux.go#L77-L79 and terminate properly. Did you see the string "received Interrupt, terminating..." print to the screen? If not, you may try other ways to send any one of these three signals to the app (such as kill).
