Public bug reported:
I use ubuntu20.04 and set static IP 192.168.11.22 in
/etc/network/interfaces. Most time it could work but sometimes the IP
changed to 192.168.11.105, which same to be a DHCP IP. I checked the
syslog and journalctl, find that eth0 same to disconnect and be re-
configured by dhcilent.:
Oct 22 10:10:03 sv-host NetworkManager[502]: <info> [1634868603.0490] device
(eth0): link disconnected (calling deferred action)
Oct 22 10:10:03 sv-host NetworkManager[502]: <info> [1634868603.0498] device
(eth0): state change: activated -> unavailable (reason 'carrier-changed') [100
20 40]
But I don't know which lead eth0 disconnect. Why eth0 doesn't get static
IP but DHCP IP when it reconnected?
