I’m experiencing issues with running sudo apt update while using Proton VPN on my Ubuntu system. Does anyone know how to resolve this problem?

I’m dealing with a frustrating issue on my Ubuntu setup, and I’m hoping someone here has a fix. So, I’ve been using Proton VPN for a while, and I really like it — good speeds and all that. But recently, I’ve run into a snag when trying to update my system. Whenever I run `sudo apt update`, it seems like it gets stuck or just returns a bunch of errors. It’s super annoying because I can’t even get the latest updates without disconnecting from the VPN first.

I’ve tried searching for solutions but haven’t found anything that works. I’ve already looked at the network settings, and it seems like everything is configured properly. What’s weird is that I can still browse the web and everything works fine with the VPN on — it’s just the package manager that goes haywire.

Has anyone else experienced this? I’ve read that sometimes VPNs can interfere with specific ports or protocols, but I’m not entirely sure how to check that. I even tried switching from the default Proton server to another one, hoping that would help, but no luck.

If it helps, I’m running Ubuntu 22.04, and I know this version should generally work well with Proton. I’ve also played around with the firewall to see if that was blocking anything, but nothing seems to be amiss there either. I can always just disconnect the VPN to complete the updates, but it feels like there should be a way to make it work while connected, right?

Would really appreciate any tips or tricks you might have! If you think I should check any specific configurations or logs, let me know. Just would love to get this sorted out so I can keep my connection secure while keeping my system updated. Thanks in advance!

    1. Ubuntu and Proton VPN Issue

      Sounds like you’re having a tough time with updates while using Proton VPN! Here’s a few things you might want to try:

      • Check if DNS is causing the problem. Sometimes, VPNs change your DNS settings. You could try using a public DNS like Google (8.8.8.8) or Cloudflare (1.1.1.1) to see if that helps.
      • Try adding the VPN’s DNS settings to your network configuration. This can be done in the Network settings under the VPN connections.
      • You may want to look into the ‘IPv6’ settings. Sometimes disabling IPv6 in your network settings can fix weird connectivity issues.
      • If you’re using a firewall, double-check that it’s not blocking outgoing connections on ports used by `apt`. Usually, it needs access to ports 80 (HTTP) and 443 (HTTPS).
      • Run `sudo apt update` with verbose logging to see more details about where it gets stuck. You can do this by replacing `sudo apt update` with `sudo apt -o Debug::Acquire::http=true update`.

      Also, your idea of switching Proton servers was a good one, but maybe give it another shot with a different location. Sometimes, certain servers have glitches or are overloaded.

      Finally, if nothing else works, it might be worth reaching out to Proton VPN support or checking their forums for any ongoing issues related to Ubuntu 22.04.

      I hope this helps! Good luck!



    2. It sounds like you’re facing a common issue where VPN configurations can interfere with the package manager’s ability to connect to repositories. A lot of times, VPNs modify the network settings in a way that can disrupt specific protocols or ports utilized by APT. To troubleshoot this, consider checking your DNS settings while connected to the VPN. Proton VPN typically provides its own DNS servers, which can occasionally lead to conflicts. You can change your DNS servers to a public DNS such as Google’s (8.8.8.8 and 8.8.4.4) in the Network Manager configuration for your connection, and see if that allows `sudo apt update` to run successfully without disconnecting.

      If changing the DNS settings doesn’t resolve the issue, you might want to explore the option of using the `apt` command with a different method, like switching the connection method to a split tunnel, which lets you route local traffic through your regular connection while still maintaining your VPN for external connections. Alternatively, you can also try temporarily disabling IPv6 if it’s enabled, as some users have reported conflicts with certain VPNs when IPv6 is active. Additionally, reviewing the logs or running `sudo apt-get update -o Debug::Acquire::http=true` can provide insights into what is happening during the update process. These steps should help you troubleshoot the problem while keeping your connection secure.
