Trying to install network-manager-l2tp on Ubuntu 18.04.

sudo add-apt-repository ppa:nm-l2tp/network-manager-l2tp
sudo apt-get update
sudo apt-get install network-manager-l2tp-gnome

After this command 

sudo add-apt-repository ppa:nm-l2tp/network-manager-l2tp

I am getting this:

    ...    
    E: The repository 'http://ppa.launchpad.net/nm-l2tp/network-manager-l2tp/ubuntu bionic Release' does not have a Release file.
    N: Updating from such a repository can't be done securely, and is therefore disabled by default.
    N: See apt-secure(8) manpage for repository creation and user configuration details.
    E: The repository 'http://ppa.launchpad.net/seriy-pr/network-manager-l2tp/ubuntu bionic Release' does not have a Release file.
    N: Updating from such a repository can't be done securely, and is therefore disabled by default.

How can I resolve this issue?

    The ppa you added is not meant to be used on 18.04. Contact the developer on https://launchpad.net/~nm-l2tp/+archive/ubuntu/network-manager-l2tp and ask them to release a Bionic version. – Jos Aug 14 '18 at 11:36

  • @N0rbert only in the case of the question you linked to, there *was* an updated ppa. I'm not so sure one exists for this package. – Jos Aug 14 '18 at 11:40
  • @Jos, right. Retracted vote. But it seems that PPA is not needed. Packages are already in [universe pocket](https://packages.ubuntu.com/search?keywords=network-manager-l2tp&searchon=names&suite=bionic&section=all) (including [`libreswan`](https://packages.ubuntu.com/search?suite=bionic&section=all&arch=any&keywords=+libreswan&searchon=names)). – N0rbert Aug 14 '18 at 11:46

    @N0rbert Good find! Care to write an answer? – Jos Aug 14 '18 at 11:49

As we discovered during conversation with @Jos in comments:

the mentioned PPA (ppa:ubuntu/network-manager-l2tp) is not needed for Ubuntu 18.04 LTS.

If you have added it - remove it with:

sudo ppa-purge ppa:ubuntu/network-manager-l2tp

All packages are available in the universe repository (see link for network-manager-l2tp and link for libreswan).

So all you need is to enable universe repository and install packages from it:

sudo add-apt-repository universe
sudo apt-get update
sudo apt-get install network-manager-l2tp-gnome

  • Perhaps the obsolete ppas should be `ppa-purge`d as well? – Jos Aug 14 '18 at 11:56

    Thanks, I could install network-manager-l2tp-gnome without ppa:nm-l2tp/network-manager-l2tp repository – R. Bogaveev Aug 14 '18 at 13:09

    Have been trying for weeks to get l2tp VPN to work.... with MERAKI's. Still no luck. So far the only reason I have the need for a Windows VM in Virtualbox. – 00fruX Dec 24 '18 at 18:25
