/etc/network/interfaces好像

auto lo
iface lo inet loopback

$ ip link show結果

$ route結果

Kernel IP routing table

我努力了

$ sudo ip addr flush dev wlo1

$ sudo ip addr flush dev enp8s0

並重新啟動，但使用openvpn連接時仍出現錯誤

答案1

我已從文件route remote_host 255.255.255.255 net_gateway中刪除client.ovpn

答案2

/sbin/ip route add 10.1.1.1/32 via 10.10.10.1和/sbin/ip route add 188.93.88.146/32 via 192.168.0.1都在前幾行執行，導致File Exists錯誤。刪除這些重複項將解決您的問題（我相信）。
