我通过 do-release-upgrade 将 22.10 升级到 23.04。升级安装新文件并进行配置后，系统重新启动，但将用户转储到恢复菜单中。进入 shell 后，网络无法正常工作。文件系统都已安装并正常工作，包括 zfs 驱动器。
但是...启动时始终无法进入图形界面。要解决这个问题，让网络正常工作会很有用。
为了让网络正常运行，以下是我尝试过的方法......
% ping ubuntu.com

% ifconfig

% cat /etc/netplan/01-network-manager-all.yaml
以下是 /etc/netplan/01-network-manager-all.yaml 中的内容
% cat /etc/netplan/01-network-manager-all.yaml
# Let NetworkManager manage all devices on this system
network:

match:

然后我尝试启动 netplan：
% netplan apply
Failed to connect system bus: Connection refused
Falling back to a hard restart of systemd-networkd.service
%
然后我尝试了 ifconfig：
% ifconfig
lo: flags=73<UP,LOOPBACK,RUNNING> mtu 65536
inet 127.0.0.1 netmask 255.0.0.0
inet6 ::1 prefixlen 128 scopeid 0x10<host>

TX packets 20866 bytes 1485964 (1.4 MB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
因此，我尝试启动 eth0 和 wifi：
% ifconfig eth0 up
% ifconfig wlp0s20f3 up
% ifconfig
