About My Setup

I'm running Ubuntu 22.04. Since toolbox isn't packaged for Ubuntu, I manually compiled it using the instructions here. Toolbox seems to be working correctly; I created a Fedora 34 container, updated it, and even ran Firefox inside of it.

What I did

1. I compiled toolbox for my system using the instructions and rebooted my system
2. I created a Fedora 34 toolbox and updated it
3. I followed toolbox-vscode's install instructions, git cloned the repository into ~/.local/share and ran the other commands
4. Went to my program's directory and ran code .
5. Was prompted to install VSCodium, installed it, installed Remote Container Extension
6. Tried rebooting to see if that solved the issue

Result

Possible causes

• I get a "F: Filesystem suffix "create" is not applicable for --nofilesystem" message after running 'code .'
• After installing locate using DNF, I saw a message that says "System has not been booted with systemd as init system (PID 1). Can't operate.... Failed to connect to bus: Host is down"
