eu tentei
$ sudo ip addr flush dev wlo1
$ sudo ip addr flush dev enp8s0
e reiniciando, mas ainda ocorrem erros ao conectar com openvpn
Responder1
Eu removi route remote_host 255.255.255.255 net_gateway
do client.ovpn
arquivo
Responder2
/sbin/ip route add 10.1.1.1/32 via 10.10.10.1
e /sbin/ip route add 188.93.88.146/32 via 192.168.0.1
ambos estão sendo executados nas linhas anteriores, resultando em File Exists
erros. Remover essas duplicatas resolverá seu problema (acredito).
