This is a bug in vpnc-scripts, not in OpenConnect per se. Upstream Debian bug: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=955016
We fixed this bug a few months ago in: https://gitlab.com/openconnect /vpnc-scripts/-/merge_requests/5 Long story short: 1) Old versions of `vpnc-script` with old versions iproute2 were silently doing the wrong thing (creating split-exclude routes always as `/32`) 2) Old `vpnc-script` with new iproute2 fails noisily, as you're showing. 3) New `vpnc-script` with new iproute2 works correctly. We need the Ubuntu package maintainers to pull in the latest vpnc- script, as Debian packagers have already done: https://bugs.debian.org /cgi-bin/bugreport.cgi?bug=955016 ** Bug watch added: Debian Bug tracker #955016 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=955016 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1871184 Title: openconnect throws errors and routing issues after connection.
