This is a beginner’s guide shows how to install (or Remove) the popular LibreOffice Office Suite in Ubuntu 24.04 LTS.

LibreOffice is a free open-source office suite, that works in Linux, Windows, MacOS, iOS, Android, and ChromeOS. It includes a word processor, spreadsheet program, presentation, vector graphics editor, math app, and database management program. And, it uses Open Document Format (ODF) as default file format, though most other major office file formats are also supported, including Microsoft Office DOCX, XML, XLSX, PPTX, and more.

The office suite is so popular that most Linux use it as default, including Ubuntu, Fedora, Debian.

However, Ubuntu 24.04 does NOT have it out-of-the-box if you installed the system with “Default selection” mode. Meaning you need to manually install the office suite afterward, for handling your spreadsheet, presentation, etc files.

This is a beginners guide shows how to decrease, move, and/or increase file/system partition in Ubuntu 24.04 LTS.

Sometimes you need to shrink a partition to free up some un-allocated disk space for other use. Or Ubuntu system is a bit small, that you need to increase its size for long time use.

In my case, I want to shrink the Ubuntu 22.04 partition to free up some space, then use the free space to increase the dual-boot Ubuntu 24.04 partition that’s a bit small for me. There’s another partition (contains personal data) sits in between the 2 Ubuntu system, so I also need to move it before being able to expand the 24.04 system.

This is a step by step beginner’s guide shows how to encrypt your home directory in Ubuntu 24.04 LTS.

As you may know, the new installer in Ubuntu 24.04 only supports encrypting the entire disk. If you want to dual boot Ubuntu with another OS in single disk, there’s no option so far to encrypt only the Ubuntu file-system partition.

In the case, you may choose to encrypt your home folder to keep personal data and files safe.

There’s NO visible difference after encrypted your home directory. You can login just like before, read and write files, run apps and play games. Because, it’s automatically decrypted using your password.

But, if you lost your computer/laptop, then no one can access your files in the home folder, without the login password or the encryption passphrase. Accessing from another operating system will show something like the screenshot below shows you:

Encrypted home is not accessible from other machine or OS

This tutorial shows how to install the most recent Chromium web browser as native .deb package in Ubuntu 24.04 and Ubuntu 22.04.

Like Firefox and Thunderbird, the popular Chromium web browser in Ubuntu repository is a Snap package that runs in sandbox environment.

For those who don’t like Flatpak and Snap packages, there are few other sources to install the Chromium browser via native Deb package.

Debian and Linux Mint repositories are the trustworthy repositories that I used to use, which however either has few different dependency libraries or lacks of arm64/armhf platform support.

So, in my opinion an Ubuntu PPA can be the better choice for beginners. It’s easy to install and maintain, though less trustworthy since Chromium does not have an official PPA.

Got app windows that do not show their icons on left (or bottom) dock panel? This tutorial may help to fix the issue in Ubuntu 24.04.

App icons that you see in system app launcher are handled by .desktop files. This kind of config file usually include a line Icon=app-icon-name, so Ubuntu and many other Linux can find and display the icon image for the app in start menu (or application menu).

If the icon file is missing from both system icons directory (usually /usr/share/icons and /usr/share/pixmaps) and user’s local icons folder (.local/share/icons), then it shows universal executable icon (the gear icon with gray square background, see the image above) instead.
