I have made some changes to my kvm server. Some machines were installed and a DNS server was set up.
Suddenly during the boot process some messages appear and the network does not start.
blkmapd[726]: open pipe file /run/rpc_pipefs/nfs/blocklayout failed: No such file or directory
systemd-networkd[732]: Failed to connect to bus: Permission denied
systemd-networkd[732]: Could not connect to bus: Permission denied
kernel: iwlwifi 0000:00:14.3 wlo1: renamed from wlan0
systemd[1]: systemd-networkd.service: Main process exited, code=exited, status=1/FAILURE
systemd[1]: systemd-networkd.service: Failed with result 'exit-code'.
systemd[1]: Failed to start Network Configuration.
systemd[1]: Dependency failed for Wait for Network to be Configured.
systemd[1]: systemd-networkd-wait-online.service: Job systemd-networkd-wait-online.service/start failed with result 'dependency'.
systemd[1]: systemd-timesyncd.service: Scheduled restart job, restart counter is at 1.
systemd[1]: systemd-networkd.service: Scheduled restart job, restart counter is at 1.
So, during startup then network remains down.

If I go to the server directly and enter sudo netplan try followed by sudo netplan apply the network works again. Does anyone have an idea where I should look?
