My YunoHost server
Hardware: x86 microcomputer, Intel Celeron N4100
YunoHost version: 11.0.4+202202091700 over Debian 11 Bullseye
I have access to my server : Through SSH, webadmin, and direct access
Are you in a special context or did you perform some particular tweaking on your YunoHost instance ? : yes
If yes, please explain: Currently running Debian 11 Bullseye. The hardware by default didn’t detect the Ethernet port, so the Debian installer added the r8168-dkms module.
Description of my issue
Whenever I need to reboot my device (due to hardware failure or a blackout), it always starts without Ethernet connectivity. After some trial and error, I found that I must manually execute dhclient directly from the hardware in order for the connectivity to return - otherwise, not even SSH will be accessible. This might be related to the fact that the device requires a DKMS driver to handle Ethernet. Oddly enough, the problem only occurred after I tested installing a GUI (LXQT) and then uninstalled it - LXQT apparently ships with its own network manager and it might have altered some configuration uncleanly.
