Dear @imustd,
Thank you for detailing the issues you've encountered while installing various versions of the VPL Jail Server. It appears that there are several key aspects contributing to the difficulties you're facing.
Version Inconsistency: It's essential to use the latest version of the VPL Jail Server for optimal performance and compatibility. I recommend downloading and installing version 4.0.0 from GitHub. This latest version has different improvements which might resolve some of the issues you're experiencing.
Network Connection Issues: Your server seems to be unable to connect to the Ubuntu repositories. This could be due to network restrictions or firewall settings on your server. Please check your network configuration and ensure that your server can reach external repositories.
Certificate Management for HTTPS/WSS Connections: The errors you're encountering suggest a lack of SSL certificates, which are necessary for secure connections. If you already possess SSL certificates, ensure they are correctly placed in /etc/vpl/key.pem
and /etc/vpl/cert.pem
. If you don't have these certificates, consider using certbot command to get a Letsencrypt certificate.
Service Management Conflicts: The error message Failed to enable unit: File /etc/systemd/system/vpl-jail-system.service already exists
indicates a conflict with the systemd service. Before proceeding with the new installation, stop the existing service using the command:
sudo systemctl stop vpl-jail-server
After stopping the service, proceed with the installation of the new version.
Installation Process: Follow the installation instructions carefully for version 4.0.0. Remember to run:
sudo ./install-vpl.sh help
for detailed command-line options and additional help.
By addressing these points, you should be able to successfully install and run the latest version of the VPL Jail Server. If you continue to face difficulties, please provide further details so we can assist you more effectively.
Best regards, Juan Carlos.
I tried installing versions 3.0.1, 2.7.1, and 2.5.3. But after compiling the daemon, I always got the same error (Failed to enable unit: File /etc/systemd/system/vpl-jail-system.service already exists.) when it was time to start the service. I tried reloading daemon, but got nowhere. All the dependencies are getting installed OK. I am using my institute's VM service, with OS Ubuntu 20.04 server. Attached is the terminal output. `INSTALLING VPL-JAIL-SYSTEM
