De 66,599 opiniones, los clientes califican nuestro Ubuntu Experts 4.9 de un total de 5 estrellas.I’m currently running Odoo 18 Enterprise on my own server and am ready to move up to Odoo 19. Because there are no custom modules or third-party integrations in the existing instance, I’m looking for a straightforward, fresh installation rather than an in-place upgrade. Your task is to: • Prepare the self-hosted environment (Ubuntu 22.04 LTS) with all required dependencies, reverse-proxy/SSL, and security hardening. • Install Odoo 19 Enterprise cleanly, activate the standard enterprise apps that ship with the platform, and confirm they all start without errors. • Import or point me to the built-in tools for moving core data from 18 to 19 (no custom code means the standard migration path should suffice). • Document every step, including commands, path...
We are looking for an experienced DevOps / GitLab CI engineer to design and implement a robust CI/CD setup for a Docker-based application consisting of a backend and a frontend, both living in the same GitLab repository. The goal of this project is to establish a clean, developer-friendly workflow that supports: Automatic internal test deployments (review apps) for feature branches Automated production deployments to a public VPS when code is merged to main This setup should follow GitLab CI best practices, especially GitLab Environments and Review Apps, and be simple for developers to use without requiring manual server access
I need a proven Airtel Black SIP configuration running on my Ubuntu machine and handled through Linphone. The goal is a clean, documented initial setup—no trial-and-error learning on my system, please. If you have already registered an Airtel SIP trunk on Linux, you’ll know the exact registrar format, the unusual port mapping Airtel uses, and the little tweaks that keep audio flowing both ways behind NAT. Here’s the workflow I’m expecting: • Install or verify the latest Linphone and any required dependencies on my Ubuntu box. • Register the Airtel Black SIP account, applying the correct proxy, authentication string, and codec priorities. • Prove the setup with at least one inbound and one outbound call (I can join you on a test call). •...
I have completed a desktop application with Lovble IA and pushed the code to a GitHub repository. Now I need it running smoothly on my own Linux server. Your job is to pull the repo, set up whatever build or runtime environment Lovble IA requires, resolve any package or dependency issues, and make sure the executable starts up reliably (ideally as a service so it can restart after reboots). The repository is ready for cloning; you will receive access as soon as we start. I expect the finished application to launch without errors from the server’s command line or through an appropriate display manager, and I’d like brief notes on every step you take so I can replicate or update the deployment later. Deliverables • Working installation of the Lovble IA desktop app on my Li...

I’m putting together a new Raspberry Pi build that will run Ubuntu rather than the standard Raspberry Pi OS. My own experience level is advanced, but I’d like another seasoned set of eyes to speed things up and help polish the system. The job focuses on: • Reviewing my current headless Ubuntu image for best-practice partitioning, bootloader tweaks, and basic hardening • Tracking down and fixing the boot-time warnings that surface in dmesg and journalctl • Suggesting and, where sensible, applying performance optimisations—overclock settings, thermal management, swap behaviour, I/O tweaks • Writing or refining a few clean Bash/Python scripts for unattended updates and off-device backups We’ll work entirely over SSH, so no hardware shipping...
Our in-house desktop application for Linux has started throwing an error that disrupts a critical workflow. I already have the full source code and a reproducible test case; what I now need is a clean, well-documented bug-fix patch that eliminates the issue without introducing regressions. Here is how I see the collaboration: • You clone the repo (Git) and replicate the bug on any mainstream Linux distro. • Diagnose the root cause, write the fix, and submit it as a unified diff/patch file plus the updated build. • Prove the fix with the supplied test case and a brief regression checklist so I can validate it quickly on my side. • Keep comments concise and follow the existing coding style; no sweeping refactors—just the focused bug fix. Once I verify that ...
I’m looking for a small, no-frills tool that I can spin up on a Linux VPS and use to blast out a single message to every recipient listed in a CSV file. The workflow is simple: I upload the CSV, paste or type the message, press send, and watch the log as each username or user_id is processed. Core expectations • Runs headless on common Linux distros (Ubuntu/Debian preferred) • Leverages the unofficial Telegram API • Accepts CSV upload (one column of @usernames or ids) and sends the same text to each entry in sequence • Streams progress to stdout or a minimal web dashboard, then saves a completion report (sent / failed) to CSV or JSON Deliverables 1. Clean, well-commented source code 2. Step-by-step setup notes I can follow on a fresh server (Dockerf...
I’m building a fresh SA-MP Mobile role-play server and need an experienced Pawn developer to move it from “just launched” to “fully stable.” The immediate job is to dive into the existing gamemode and clean up the mission/event scripts. They work, but they’re rough around the edges and don’t yet flow the way a live RP community expects. At the same time, I want the vehicle-handling parameters tuned so cars feel consistent across different client devices. While you’re in the codebase, I also need you to hunt down and eliminate the three big pain points the testers keep flagging: random crashes, noticeable frame-rate dips, and a handful of features that sometimes just stop responding. The sooner those are gone, the sooner we can open the doo...
We need a full-stack technical staff member with expertise in Java microservice development (Spring Cloud), message queues (Kafka/RabbitMQ), databases and caching (MySQL/Redis), Linux server deployment and maintenance, Nginx gateway configuration, and distributed system debugging to complete the deployment.
I have an existing code-base that needs to be compiled, configured, and deployed on a CentOS 7 server. The stack spans several languages (the repository mixes Java, Python, a bit of C++, and some PHP utility scripts) so I need someone comfortable moving through polyglot projects without breaking stride. (Developed independently using a non-Java language) The immediate goal is a repeatable deployment: building the artefacts, resolving library dependencies, wiring in systemd service files, and validating that everything starts cleanly after a reboot. You’ll work directly on my CentOS 7 instance (SSH access provided) and document any package or kernel-level tweaks you make so I can reproduce the setup on staging and production later. Because the code also ships to a small cross-pla...

I’m looking for someone who can install and configure OpenClaw on a fresh Linux environment (Ubuntu 24). Once it’s in place I need it tuned specifically for running automation scripts—no other features are required right now. The job is considered finished when: • OpenClaw is installed from source or packages, whatever is most stable on Ubuntu 24. • The automation‐script module is enabled and a sample script executes without errors. • I have a brief README outlining the key commands to start, stop, and update the service. If you’ve compiled similar tools or set up CI-style script runners before, this should be straightforward. open claw open site and login and bet bhave of me what i say to him ho and this mach and bet liek that

I’m ready to rebuild my GoDaddy VPS: it currently runs CentOS and hosts my company websites behind Nginx with SSL enabled. I want the server re-imaged to the latest stable Ubuntu, with every element of the existing stack preserved and an additional n8n instance installed. Scope of work • Perform and store an off-box, full backup of all site files, databases, and current Nginx configurations before any changes begin. • Re-provision the VPS on Ubuntu, harden the OS, and apply basic firewall rules. • Restore my websites, bringing Nginx back online with the original virtual host blocks and SSL certificates so no visitor notices the change. • Install n8n (Docker or native systemd service—whichever fits best on Ubuntu) and expose it securely over HTTPS ge...
I need reliable freelance computer-hardware engineers who can visit my customers’ offices and homes across India and carry out installation services—specifically Linux installation on their machines for everyday desktop use. Here’s what a typical call looks like: I send you the location and preferred Linux flavour (most often Ubuntu or Mint, though customers occasionally ask for Fedora or Debian). You arrive on site with a bootable USB/DVD, install the OS on a new or existing desktop or laptop, set up common drivers, configure the network, and verify that everything—from Wi-Fi to printers—works smoothly before hand-over. I cover any reimbursable travel expenses that we agree on in advance, and you invoice me once the job is signed off by the customer. So...
I have, 40-core machine with 1 TB of RAM that needs to be turned into a practical development box for my team. The goal is to have both Windows Server and Ubuntu Server installed side-by-side, each ready for daily coding, testing, and collaboration. Here’s what I need from you: • Plan and carry out the installation of the two operating systems, making sure they coexist cleanly (dual-boot, virtualization, or any proven approach you recommend). • Partition and configure storage so that each OS has ample, clearly labeled space. • Enable remote access for multiple developers, with sensible user and permission settings already in place. • Apply baseline security hardening and system updates so we start from a solid, up-to-date foundation. Once finished, I s...
