I can't use the script to install the dependency environment because the installation source is not found for ipv6 access.

if it's possible, please send screenshot, in whitch vps provider you have problem?

IF MY SERVER DOES NOT HAVE AN IPV6 NETWORK, THERE WILL BE NO 404 NOT FOUND, IF THERE IS AN IPV6 NETWORK, THE IPV6 NETWORK WILL BE USED FIRST TO UPDATE THE INSTALLATION SOURCE, IF THE IPV6 UPDATE MAY APPEAR 404 NOT FOUND, YOU CAN FIND A SERVER WITH IPV4 + IPV6 TO TEST IT.

please check it now

I have now switched to the debian11 system, I used another script, docker, and now without any issues. This is my server IPV6 address, 2404:8c80:0:1009:39d:2e00:73ab:3d95, 2404:8c80:0:1009:3ae:8ea2:7889:b873, its network is normal, you can try to ping it. If possible, can I send you my server account password and you can test it? You will need to provide private contact information though.

i updated the script

GOOD！I got it to install this time, Ubuntu 20.04, but I see the warning message during the installation, can you add the IPV6 feature of ocserv?

[do02fw]

I updated my system to Ubuntu 22.04 and I don't have this problem anymore, I can boot my system normally.

in which os you had such a issues?

I had this problem with ubuntu 20.04, I consulted the cloud server vendor and they replied to me that their system was not configured with python environment and variables, when I upgraded from 20.04 to 22.04 and then installed the script without any problems, I think the vendor has made changes or streamlined the system to cause this. If you can, you could add something to the script that detects environment variables and automatically fixes them, and that would solve the situation.

Do you know how to get ocserv to give priority to ipv6? When I connect to anyconnecy and use the ping command, it returns ipv4 results first, unless I add -6 to the ping it will return ipv6 results, how do I get ocserv to use ipv6 first?

[alirezamarzban]

to enable ipv6, you must: nano /etc/sysctl.conf find this line:

net.ipv6.conf.all.forwarding=1

change it to: net.ipv6.conf.all.forwarding=1 then presse ctrl + x and press y and presse enter to save the changes then run this command: sysctl -p then go to ocserv.conf by this command: nano /etc/ocserv/ocserv.conf find this line:

ipv6-network = fda9:4efe:7e3b:03ea::/48

change it to: ipv6-network = fda9:4efe:7e3b:03ea::/48 now find this line:

ipv6-subnet-prefix = 128

or

ipv6-subnet-prefix = 64

change it to: ipv6-subnet-prefix = 128 or ipv6-subnet-prefix = 64 then restart ocserv to take the effects by using script, or use this command: systemctl restart ocserv all is done

to enable ipv6, you must: nano /etc/sysctl.conf find this line: #net.ipv6.conf.all.forwarding=1 change it to: net.ipv6.conf.all.forwarding=1 then presse ctrl + x and press y and presse enter to save the changes then run this command: sysctl -p then go to ocserv.conf by this command: nano /etc/ocserv/ocserv.conf find this line: #ipv6-network = fda9:4efe:7e3b:03ea::/48 change it to: ipv6-network = fda9:4efe:7e3b:03ea::/48 now find this line: #ipv6-subnet-prefix = 128 or #ipv6-subnet-prefix = 64 change it to: ipv6-subnet-prefix = 128 or ipv6-subnet-prefix = 64 then restart ocserv to take the effects by using script, or use this command: systemctl restart ocserv all is done

Thanks, I have enabled IPV6, but it has a low priority, when I access the internet, it will give priority to ipv4, how can I modify the route to increase the priority of ipv6?
