The correct timezone affects more than the clock on your screen. It drives cron job scheduling, systemd timer execution, log file timestamps, database record timing, and SSL certificate validity checks. A mismatched timezone can cause scheduled jobs to fire at the wrong hour and make log timestamps impossible to match with real-world events. This guide shows how to change timezone on Ubuntu using the timedatectl command (the recommended approach for servers and remote machines) and through the graphical Date & Time settings on desktop systems. The steps apply to all current Ubuntu releases including 24.04 and 26.04. <strong>Prerequisite:</strong> Only the root user or a user with sudo access can change the system timezone. Check the Current Timezone Before You Change It Run timedatectl with no arguments to see the active timezone and clock status: bashtimedatectl Sample output: Local time: Mon 2026-04-27 08:33:20 UTC…

TeamViewer is a proprietary cross-platform remote access application for remote control, desktop sharing, file transfer, and online meetings. It is one of the most widely used remote support tools in the world, available for Windows, macOS, Linux, iOS, and Android. TeamViewer is not included in the Ubuntu repositories because it is proprietary software. This guide covers how to install TeamViewer on Ubuntu 18.04 using the official .deb package. The same steps apply to Ubuntu 16.04, Debian, Linux Mint, and Elementary OS. <strong>Prerequisite:</strong> You need sudo access. Install TeamViewer on Ubuntu: Download the .deb Package Download the official TeamViewer .deb package. The _amd64.deb suffix indicates this package is for 64-bit x86-64 systems. For ARM-based machines, download the appropriate package from the TeamViewer Linux downloads page: bashwget https://download.teamviewer.com/download/linux/teamviewer_amd64.deb Install the package using apt. The ./ prefix tells apt this is a local file path, not a package name from the repositories: bashsudo apt install ./teamviewer_amd64.deb At the 'Do you want to continue?' prompt, type Y and press Enter. The installer resolves and installs the Qt5 library dependencies that TeamViewer requires for its graphical interface. TeamViewer also registers its official APT repository automatically during this process, which enables future updates.…
