I think this is a duplicate of the following, although the xl2tpd errors manifest slightly differently : https://bugs.launchpad.net/ubuntu/+source/xl2tpd/+bug/1951832 https://bugs.launchpad.net/ubuntu/+source/xl2tpd/+bug/1968336
But as others have confirmed, Ubuntu 22.05's xl2tpd-1.3.16-1 is broken, so the most likely culprit. network-manager-l2tp uses kl2tpd as its default L2TP daemon and falls back to xl2tpd if it can't find kl2tpd. To confirm it is only xl2tpd that is broken for you, try installing kl2tpd with the following : sudo apt install golang-go go install "github.com/katalix/go-l2tp/...@latest" sudo mkdir /usr/local/sbin sudo cp go/bin/kl2tpd /usr/local/sbin -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1970068 Title: L2TP+IPSec not working after upgrade to 22.04 LTS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1970068/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
