I've upgraded my centos 8 test server (running on virtualbox 6.1.30 r148432 @ windows 10 host) to centos 8 stream and after the upgrade I can't ping any ip address neither local nor public.
Code: Select all
ping google.com
ping: socket: Address family not supported by protocol
Code: Select all
sudo ping -4 google.com
trying to go deeper, I've realized that there is a lot of errors in /var/log/messages regarding ipv6 from network manager:PING google.com (142.250.185.142) 56(84) bytes of data.
64 bytes from fra16s50-in-f14.1e100.net (142.250.185.142): icmp_seq=1 ttl=56 time=16.10 ms

these were successfuly eliminated by disabling ipv6 in nmcli

sudo nmcli con modify Wired\ connection\ 1 ipv6.method "disabled"
kernel runs with ipv6.disable=1 option (even before upgrade), output of

anything else works fine including ssh, dnf, dig, etc.Linux hostname 4.18.0-358.el8.x86_64 #1 SMP Mon Jan 10 13:11:20 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux
