Ubuntu announced the first point release of Ubuntu 24.04 LTS few days ago with lots of bug-fixes and performance improvements. It’s time to upgrade to the new LTS, for users who were worrying about the stability issues.

Ubuntu 24.04 is the current Long Term Support (LTS) release with 5 years of standard support until 2029, another 5 years Ubuntu Pro support until 2034, as well as legacy support until 2036. It features Linux Kernel 6.8, GNOME Desktop 46, and various other changes, see the official release note for details.

The new LTS had various upgrade issues, and stability / performance issues, for apps and hardware including Nautilus file manager, the new tiling assistant, NVIDIA on Wayland, Pipewire sound server, hybrid GPU machines, Remmina RDP client, online accounts, cursor themes, and more!

Last updated: August 30, 2024 — 4 Comments

Ubuntu 24.04.1, the first point release of the current Ubuntu LTS, was announced last night on Aug 29.

The release includes updated CD images. The livecd-rootfs build system re-enables ability to build HyperV desktop images, and allows to build iso installer images that would install Ubuntu Core Desktop to target device.

The new release also fixed various upgrade issues. It now prevents upgrading from desktop systems installed with TPM-backed FDE. It fixed that the upgrade breaks iptables-persistent and netfilter-persistent usage, and removed the XFS /boot upgrade check. It as well fixed many other upgrade issues, including hang due to search for obsolete software, and long time delay when installing gnome-remote-desktop 46.

Last updated: October 6, 2024 — Leave a comment

This tutorial shows how to automatically create, delete files/folders, and/or write parameters into config files at startup in Ubuntu and other Linux using systemd.

This can be useful if some configuration do not persistent and reset to default on every boot, or you want to clean up something either on every boot or after every time period.

Advanced users can manually create a script, and run it via either crontab schedule task or custom systemd service. But, here I’m going to show you how to do the trick using tmpfile.d, a built-in configuration for creation, deletion and cleaning of volatile and temporary files.

How to Encrypt Your Home Folder in Ubuntu 24.04

Last updated: July 23, 2024 — 1 Comment

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:

Fix Missing App Icon in Left Dock / Panel in Ubuntu 24.04

Last updated: June 17, 2024 — 14 Comments

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.

Last updated: April 27, 2024 — 2 Comments

After doing a fresh install of Ubuntu system, users usually have to do a list of configurations before the system is ready for use. And, here are a list of the top things I can tell for the Ubuntu 24.04 LTS.

1. Install back some default apps

If you didn’t choose “Extended selection” option while installing Ubuntu 24.04, then you’ll find that many apps are missing!

There’s no office suite, no video/music player, no email app … If you need some of them, then just launch the new App Center from left panel, then search and install any of them back.
