I am trying to configure L2TP client on our Ubuntu 22.04 Server. I have configured the credentials and see the following errors in the Log

Any ideas what i am missing?

I also see that any change i make to the interface of Network Manager, does not persist and gets reverted to earlier value when i enable the VPN.

So for example, if earlier the name of VPN connection was VPN OLD if change the name of the VPN to "VPN NEW" and try to enable the VPN,the name get reverted back to VPN OLD.

Any help on how to fix this would be great, thanks

You need to upgrade to xl2tpd 1.3.16-1ubuntu0.1 or later, e.g.:

sudo apt update
sudo apt upgrade xl2tpd

I would also recommend installing the newer network-manager-l2tp (and network-manager-l2tp-gnome) package(s) from :

I have no idea what is going wrong with the rename, but it wouldn't hurt doing a sudo apt upgrade to upgrade all of the packages, it might even fix that rename issue.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
