Thanks! The solution worked as described.

However after a recent apt upgrade the VPN suddenly stopped working. I did not keep a log of the updated packages though, but I see that the client shows Version 3.15.1
The app launches, but after hitting the "Connect" button a popup window shows with "Unknown error ocurred. Try Again".
Any ideas on what to look for?

I found that after going back to 3.15.0 it works again!
You can download older versions at https://docs.aws.amazon.com/vpn/latest/clientvpn-user/client-vpn-connect-linux-release-notes.html

This worked for me...I have the latest AWS VPN version and Ubuntu 24.04.1 LTS

wget http://archive.ubuntu.com/ubuntu/pool/main/o/openssl/libssl1.1_1.1.0g-2ubuntu4_amd64.deb
sudo dpkg -i libssl1.1_1.1.0g-2ubuntu4_amd64.deb

We should appeal to AWS to make the VPN client supported on Ubuntu 24. I have filled out a support ticket. In the reply they said they are working on it but they did not specify an ETA. I did not understand whether that meant "actively working on it", or just "it's it's the backlog" kind of progress. Has anyone else conversed with AWS regarding this?

@varfrog is their any update from aws side in your support ticket? It has been two weeks. Can you share link to your support ticket?

@jannel-cloubi aren't you facing the issue of "Unknown error ocurred. Try Again".

@ferchor2003 I also downgraded aws vpn clinet to version 3.15.0 from version 3.15.1, still I am getting "Unknown Error Occurred" error message.

Here is the log message that is saved to the log file located at:- /home/username/.config/AWSVPNClient/

Tmds.DBus.ConnectException: Connection refused �awsvpnclient ---> System.Net.Internals.SocketExceptionFactory+ExtendedSocketException (111): Connection refused �awsvpnclient at System.Net.Sockets.Socket.DoConnect(EndPoint endPointSnapshot, SocketAddress socketAddress) at System.Net.Sockets.Socket.Connect(EndPoint remoteEP) at System.Net.Sockets.Socket.UnsafeBeginConnect(EndPoint remoteEP, AsyncCallback callback, Object state, Boolean flowContext) at System.Net.Sockets.Socket.BeginConnect(EndPoint remoteEP, AsyncCallback callback, Object state) at System.Net.Sockets.Socket.ConnectAsync(EndPoint remoteEP) at System.Net.Sockets.SocketTaskExtensions.ConnectAsync(Socket socket, EndPoint remoteEP) at Tmds.DBus.Transports.TransportSocket.ConnectAsync(EndPoint endPoint) at Tmds.DBus.Transports.TransportSocket.ConnectUnixAsync(AddressEntry entry, CancellationToken cancellationToken, Boolean supportsFdPassing) at Tmds.DBus.Transports.Transport.ConnectAsync(AddressEntry entry, ClientSetupResult connectionContext, CancellationToken cancellationToken) at Tmds.DBus.DBusConnection.ConnectAsync(ClientSetupResult connectionContext, Action1 onDisconnect, CancellationToken cancellationToken)

Have you figured out any solution for this? Is it working fine for other in Ubuntu 24.04.1?

It is a private support ticket. I've created 3 tickets so far, they seem to be sending a template answer, saying there's no ETA. And the wording is so that I can't figure out if the thing is in progress or not

@ferchor2003

Try see this issues.

1 - DBus service is not running: DBus is an inter-process communication (IPC) system that many applications on Linux use for communication. If the service is down, the AWS VPN client may not be able to communicate with other necessary system components.

2 - Firewall/Network issues: The VPN client could be trying to connect to a blocked or incorrect endpoint.

3 - VPN service is not started: The VPN service might not be running, or the configuration files could be incorrect.

4 - Incorrect socket configuration: The socket connection to the DBus or VPN management service may be misconfigured, leading to the connection refusal.

Hi, @ferchor2003 :

I got it working by installing the dbus-x11 package and restarting.

nano ~/.profile

Add:

export DOTNET_SYSTEM_GLOBALIZATION_INVARIANT=1
DOTNET_SYSTEM_GLOBALIZATION_INVARIANT=1

i still get this error using ubuntu 24

desktop file did not specify exec field

I had to downgrade to version 3.13.0 to works, removed aws from apt list and not planning to update.

Hello. I solved this issue with add Exec=env DOTNET_SYSTEM_GLOBALIZATION_INVARIANT=1 /opt/awsvpnclient/AWS\ VPN\ Client %u
in "/usr/share/applications/awsvpnclient.desktop"

Is anyone interested in running a VM for the VPN client, and route traffic through the VM? I have a few ways to set that up and can share some updated scripts.

@aadit-panta I am getting the same issue as you even after installing version 3.15.0. did you have any luck finding a fix?

@aadit-panta actually I was able to fix the issue by following these instructions 🎉

Got it working with ubuntu 24.04 and v 3.12.0 after a reboot.

The service runs, but I can't see the UI when clicking on the AWS icon. However, after a reboot, it worked.

Ubuntu 24.04 is now supported. At last!

It would be nice to provide an update to this guide to undo what we did here, for those that don't know how to do it, now that there is official support for it.

This is what I did:

# check if libssl1.1 has any dependencies
sudo apt-cache rdepends libssl1.1
sudo apt-get remove --purge libssl1.1
sudo apt update
sudo apt autoremove
sudo apt autoclean
sudo apt-get remove --purge awsvpnclient
ls -l /opt/awsvpnclient
sudo rm -rf /opt/awsvpnclient/awsvpnclient
sudo rm -rf /opt/awsvpnclient/ConnectionInfoFiles
sudo systemctl status awsvpnclient

Then follow the instructions on AWS to install AWS VPN 4.1+

Using Ubuntu 24.04.1 LTS

Hi @mrbeiertz , just saw your comment and then realized that 4.1 is out now! Thanks a lot!

I followed your instruction to uninstall the old version then installed the new version from here.

Thought this time installation, starting and connection was without any hassle, but I was still unable to access the private resource. Then I looked into the logs and found this error

/opt/awsvpnclient/Service/Resources/openvpn/configure-dns: line 24: systemd-resolve: command not found

I have to create a symbolic link named systemd-resolve that points to resolvectl.

sudo ln -s /usr/bin/resolvectl /usr/bin/systemd-resolve

These additional steps got the vpn client working on ubuntu machine.

The AWS VPN Client is now officially available for Ubuntu 24.04. If you are still experiencing issues, you can follow the official troubleshooting process.

I had an issue with the DNS, and just by adding one line of instruction in the OpenVPN configuration file, I was able to connect to the private resource.
