GlobalProtect failed logout

[Zoïs Moitier]

Hello,

I use the command `sudo openconnect --protocol=gp 
--csd-wrapper=/usr/libexec/openconnect/hipreport.sh vpn.ucmerced.edu` to 
connect, it works perfectly and then when I ctrl+c to stop the vpn said 
that the logout fail but after that the vpn does stop on my side. Here 
what I get in the command line:

```bash

^CPOST https://vpn.ucmerced.edu/ssl-vpn/logout.esp
SSL negotiation with vpn.ucmerced.edu
Connected to HTTPS on vpn.ucmerced.edu
Invalid user name
Logout failed.
RTNETLINK answers: No such process
RTNETLINK answers: No such process
User cancelled (SIGINT/SIGTERM); exiting.

```

After discussing with the IT department, it seem than I am never logout 
on the vpn side.

If I add the options `--script "sh -x 
/usr/share/vpnc-sripts/vpnc-script"` and `-vvv --dump`, after the ctrl+c 
I think that the interesting part are

```bash

< <?xml version="1.0" encoding="UTF-8" ?>
<
<     <response status="error">
<         <portal>UCM_VPN-N</portal>
<         <domain>%28empty_domain%29</domain>
<         <user>my_user_name</user>
<         <computer>pop-os</computer>
<         <error>Invalid user name</error>
<     </response>
Invalid user name
Logout failed.

```

and

```bash

+ /sbin/ip route replace default via 192.168.0.1 dev wlp0s20f3 via 
192.168.0.1 dev wlp0s20f3
Error: argument "via" is wrong: use nexthop syntax to specify multiple via

```

I use the official version from the repository (version 8.05-1) on 
Pop_OS! 20.04.


How can I fix this?
