Public bug reported: On starting an openconnect session, I get error messages that appear to be caused by interactions with /sbin/ip:
sudo openconnect --syslog --deflate --disable-ipv6 \ "--authgroup=$AUTHGRP" "--user=$USERNAM" "$VPN_URL" Please enter your username and password. Password: Error: any valid prefix is expected rather than "dev". Error: ipv4: Invalid values in header for route get request. Usage: ip route { list | flush } SELECTOR ip route save SELECTOR ip route restore ip route showdump ip route get [ ROUTE_GET_FLAGS ] ADDRESS [ from ADDRESS iif STRING ] [ oif STRING ] [ tos TOS ] [ mark NUMBER ] [ vrf NAME ] [ uid NUMBER ] [ ipproto PROTOCOL ] [ sport NUMBER ] [ dport NUMBER ] ip route { add | del | change | append | replace } ROUTE Maybe the output format of /sbin/ip changed since openconnect was last updated?
