Ubuntu 20.04, KVM

After installation the server.conf has invalid second line (10.0.0.1) and therefore OpenVPN service doesn't start properly:

local 78.24.218.120
10.0.0.1
port 1194
proto udp

The problem comes from command at line 106 of the installation script: ip -4 addr | grep inet | grep -vE '127(\.[0-9]{1,3}){3}'. In my case it outputs following:

inet 78.24.218.120 peer 10.0.0.1/32 brd 78.24.218.120 scope global ens3

Then this string is cut by / separator but saves that 10.0.0.1 garbage.

Interesting — that garbage appears at the server.conf file no matter if I hit Enter during the first step of the installation or if I type my clear IP address manually.

If I manually remove that line, than VPN works fine.

I guess it is possible to edit regular expression to deal with this issue.
