Doesn't work out-of-the box on debian 12 (bookworm) as a systemd unit under yggdrasil user, only as root; am trying to debug why

[ghost]

Hi,

Sorry in advance for the amount of text

I installed yggdrasil from system's repo onto a freshly installed Debian 12 (bookworm):

1.1. It didn't automatically create /var/run/yggdrasil/ and subsequently complained about it's socket being unachievable

2023/10/21 23:48:48 Admin socket failed to listen: listen unix /var/run/yggdrasil/yggdrasil.sock: bind: no such file or directory

The rights are set as follows

The systemd unit config is vanilla one from deb package

1.2. Sometimes instead of the error above It gives me a permission error during interface creation (even when ran as 'yggdrasil').
It seems to be a race condition somewhere. I found it by restarting yggdrasil in a while true loop for debugging. Most errors are the same as the 1st one, and occasionally are as below.

panic: operation not permitted

3. Package manager's version doesn't give me the version number, only "unknown" instead
4. Everything works as intended under root/sudo, but not under yggdrasil user, main user (1000), nor systemd unit (also yggdrasil user); both with -useconffile and -autoconf

Main user has the following groups:

cdrom floppy audio dip video plugdev users netdev bluetooth

I tried updating to latest release, but nothing seems to have changed

Build name: yggdrasil-develop
Build version: 0.5.0rc2

Where should I look next?
I would appreciate any pointers)

Thanks

i have hit this too when using an lxc holding debian 12.
my main workstation with debian 12 has a bunch of custom setup so i forget if that is also happening there.

(this was on the recent 0.4 debs)

Hello @thomas-ives and @majestrate,

I am the maintainer of Yggdrasil packages in the Debian distribution (though not of the Yggdrasil packages that the Yggdrasil project produces). We are a bit confused about this bug report. Can you help by:

1. Telling us whether you are using the debs from Yggdrasil or from Debian?
2. Telling us whether you have ever used debs from a different source? (Yggdrasil or Debian)
3. Sending the output of grep yggdrasil /var/log/dpkg.log?

Thanks,

John
