Activation of network failed with my VPN

Aura

I have a problem with my vpn when I want to activate it, it was working fine until today. I'm on Ubuntu 20.04 and my vpn is an L2TP vpn.

I reinstalled the VPN several times but impossible I always have the same errors, in the syslogs too.

You seem to be using libreswan, but with network-manger-l2tp IPsec phase 1 and 2 settings for strongswan (i.e libreswan doesn't use an exclamation mark). Try removing the phase 1 & 2 settings. Probably also do a `sudo apt purge libreswan`, Then reinstall either libreswan or strongswan.

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.
