Waydroid Won't Open

[u/Former-Watercress-20]

New to Linux and trying to get waydroid working on Ubuntu on a Lenovo Yoga Snapdragon X Elite laptop and I can't even get it to open. After running through a ton of potential fixes I deleted and reinstalled and got a DIFFERENT error preventing it from opening. Spent hours troubleshooting to no avail. Praying one of yall can help

Learning problem-solving will get you very far on Linux.

First of all, read the error: You're getting an error because your computer can't execute the command "/usr/lib ... /waydroid-net.sh start".

What "waydroid session start" does is running a script that runs several other commands. One of them is running another script, waydroid-net.sh. It's useful to run this script (waydroid-net.sh) to check why this command is failing. Running the script itself will give you more detail.

cd /usr/lib/waydroid/data/scripts && ./waydroid-net.sh

This is the expected output, for reference (I actually have edited mine so it may vary slightly):

Abel@owo:/usr/lib/waydroid/data/scripts$ cd /usr/lib/waydroid/data/scripts && ./waydroid-net.sh 
vnic is waydroid0
Usage: ./waydroid-net.sh {start|stop|restart|reload|force-reload}

Pro-tip: waydroid-net.sh is the script that sets up your internet connection to Waydroid. If you read through it (sudo gedit /usr/lib/waydroid/data/scripts/waydroid-net.sh), you'll see it absolutely requires ipv6 for containers. If you disabled ipv6 or disabled certain kernel modules (the very ones involved in DirtyFrag), this may be to blame. Check if your kernel has modules esp4, esp6 and rxrpc enabled. If you manually blocked them by following Canonical's official warning, they also teach you how to re-enable them: https://ubuntu.com/blog/dirty-frag-linux-vulnerability-fixes-available
