How to Install Geany 2.0 in Ubuntu:

Geany does not provide official packages for Linux. Besides building from source code, user can choose to use the universal Flatpak package or an unofficial Ubuntu PPA.

Option 1: Flatpak package

The Flatpak package is an universal package format can be installed in most Linux, however it runs in sandbox.

To install Geany as Flatpak package, press Ctrl+Alt+T on keyboard to open terminal. Then, run the 2 commands one by one:

First, install Flatpak daemon in case you don’t have it:
```
sudo apt install flatpak
```

Then, install Geany Flatpak package:

flatpak install https://dl.flathub.org/repo/appstream/org.geany.Geany.flatpakref

After installation, search for and launch Geany from either overview screen or start/application menu depends on your desktop environment.

NOTE: For first time installing Flatpak app, needs a log out and back in to make app icon visible.

Option 2: Ubuntu PPA

For those who hate running app in sandbox, I’ve uploaded the package into this unofficial PPA. So far, it supports for Ubuntu 20.04, Ubuntu 22.04, Ubuntu 23.04, and Ubuntu 23.10 on x86_64, arm64/armhf CPU architecture types.

1. First, press Ctrl+Alt+T on keyboard to open terminal. When terminal opens, run command to add the PPA:

sudo add-apt-repository ppa:ubuntuhandbook1/geany

Type user password (no asterisk feedback) when it asks and hit Enter to continue.

2. Linux Mint users may need to manually refresh system package cache after adding PPA, though it’s done automatically in Ubuntu 20.04 and higher.

To do so, run command:

sudo apt update

3. Finally, install Geany 2.0 as well as plugins by running command:

sudo apt install geany geany-plugins

After successfully installed the packages, search for and launch the IDE from overview or application menu and enjoy!

Uninstall Geany 2.0

For Geany IDE installed as Flatpak package, just run the command below to remove it:

flatpak uninstall --delete-data org.geany.Geany

Also, run flatpak uninstall --unused to clear useless run-time libraries.

For the IDE installed from Ubuntu PPA, remove it by running command in terminal (Ctrl+Alt+T):

sudo apt remove --autoremove geany geany-plugins-common

Also, remove the PPA either by running command in terminal:

sudo add-apt-repository --remove ppa:ubuntuhandbook1/geany

Or, use “Software & Updates” by removing the source line under ‘Other Software’ tab.

How to Install Local .deb file in Ubuntu 24.04

Last updated: September 1, 2024 — 3 Comments

Since Ubuntu 23.10, there’s no longer “Software Install” option for opening/installing .deb files in your Downloads folder. This is probably due to switch to the new ‘App Center’, that some features are not fully implemented.

When you double-clicking a .deb file from Downloads folder, it will pop-up a dialog saying “Could Not Display ‘file_name.deb’ There’s no app installed for ‘Debian package’ files“. And, neither option will work for installing the package.

UPDATE: App Center in Ubuntu 24.04 finally added back the feature to install local .deb! Just double-click on the package in file manager to launch and install.

So, if you’re trying to install an application using local .deb format package, here are 3 workarounds for you.

Option 1: use Gdebi package installer

Gdebi is a simple tool to view and install local .deb file. It’s a popular application that’s using as default in Linux Mint.

1. First, press Super (Windows logo) key to open overview screen. Search for and launch “App Center”.

2. When ‘App Center’ opens, use it to search and install Gdebi. You may need to select “Filter by Debian packages” to make it visible.

3. Once you installed the tool, right-click on your local .deb file, and click on “Open With…” option.

In next pop-up dialog, find out and select “Gdebi Package Installer” and turn on “Always use for this file type“, finally click Open.

4. After that, you can double-click any .deb file to open with the Gdebi package installer. When the tool opens, you may view the package info and click “Install Package” to install it into your system.

Option 2: Use apt command

For those who are familiar with Linux command, your local .deb file is easy to install via a single command.

It’s:

sudo apt install /path/to/file.deb

Definitely, you need to replace ‘/path/to/file.deb‘ to yours.

Instead of typing manually, simply open terminal (via either Ctrl+Alt+T shortcut or ‘Open in Terminal’ context menu), then drag and drop .deb file into terminal after typing sudo apt install plus a blank space.

Finally, hit Enter to run the command, type user password (no asterisk feedback) to authentication, and answer y if it asks to confirm.

When installation done, it will output something like ‘N: Download is performed unsandboxed as root as file ‘/path/to/file.deb’ couldn’t be accessed by user ‘_apt’. – pkgAcquire::Run (13: Permission denied)’. Just skip the non-fatal warning. Your app should be properly installed when you see the terminal output message.

Option 3: Use GNOME Software

If you want to restore the new App Center to classic Ubuntu Software, then GNOME Software can be a better choice.

GNOME Software supports Deb, Flatpak, and Snap packages. However, it will be always run in background that takes about 200 MB memory in my case.

If you don’t care about the memory consumption, then press Ctrl+Alt+T to open terminal, and run command to install GNOME Software:

sudo apt install --install-suggests gnome-software

Skip --install-suggests if you don’t want to enable Flatpak support.

After that, you can right-click on local .deb file, and select “Software Install” from Open With dialog to launch GNOME Software to install it.

Uninstall:

If you don’t use Gdebi or Gnome Software anymore, open terminal (Ctrl+Alt+T) and run command to uninstall:

Uninstall Gdebi:

sudo apt remove --autoremove gdebi

Or, uninstall Gnome Software via command:

sudo apt remove --autoremove gnome-software

Last updated: April 28, 2024 — 2 Comments

The new tiling assistant extension in Ubuntu 23.10 and Ubuntu 24.04 has indicator support! Here’s how to enable it and fix the missing icon.

Ubuntu introduced a new system extension called “Tiling Assistant” since 23.10. With it, user can easily tile window to half or quarter of screen either via mouse dragging or keyboard shortcut.

The extension also has an indicator applet on panel, allows user to select a layout to start tiling with ‘Super + Tab’ look like menu for all opened windows. See the short video:

The feature is useful, however lack of indicator icon on panel, possibly due to bug or building issue. This tutorial is going to show you how to enable the indicator as well as add back the icon, so it will look like the screenshot below:

Step 1: Enable the Indicator Applet

To enable the indicator, user can either run single command in terminal or use ‘Dconf Editor’ configuration tool.

Option 1: Press ‘Ctrl + Alt + T’ key combination on keyboard to open terminal. When terminal opens, run the single command below to do the job:

gsettings set org.gnome.shell.extensions.tiling-assistant show-layout-panel-indicator true

Option 2: Or, first search for and install “Dconf Editor” from App Center.

Then, launch “Dconf Editor” and navigate to org/gnome/shell/extensions/tiling-assistant. Finally, scroll down, find out and turn on ‘show-layout-panel-indicator’.

Step 2: Fix missing icon issue

As mentioned, the indicator is missing icon on panel. To fix it, you may install the community version of “Tiling Assistant” from EGO (extensions.gnome.org), then copy the icon files to use for system built-in extension.

1. First, open App Center, then search for and install “Extension Manager“.

Install Extension Manager in Ubuntu Software/App Center

2. Then, launch “Extension Manager” and use it to search and install “Tiling Assistant” community edition under Browse tab.

Press Ctrl+Alt+T on keyboard to open terminal, when terminal opens, run commands:

navigate to the user installed extension directory:

cd ~/.local/share/gnome-shell/extensions/tiling-assistant@leleat-on-github/

```
Type user password (no asterisk feedback) when it asks and hit Enter.

Finally, use “Extension Manager” to turn off and turn back on ‘Ubuntu Tiling Assistant’ to apply change. And, remove the user installed ‘Tiling Assistant’ extension. Or, simply log out and back in.

Change Folder Color & Add Emblem in Ubuntu 24.04, 22.04

Last updated: May 4, 2024 — 2 Comments

Ubuntu has a “Folder Color” package in system repository, allows to change the color and add emblem for individual folder. However, it’s only available for Ubuntu LTS, and uses the old default ‘Humanity’ icon theme, which looks very outdated.

To fix the issue, a free open-source yaru-colors-folder-color project was created to work along with system default ‘Folder Color‘, so to have folder icon in different colors while keep using default Yaru theme.

The project is discontinued, due to switch to the new “Folder Color” project, which works out-of-the-box with Yaru colors integration. And, not only for Ubuntu LTS, but also supports all current short-term releases, such as Ubuntu 24.04.

With it, user can right-click on any folder, to get the menu to change folder color to ‘Blue’, ‘Brown’, ‘Green’, ‘Grey’, ‘Pink’, ‘Purple’, ‘Red’, and ‘Yellow’. As well as adding emblem such as ‘Important’, ‘In Progress’, ‘Favorite’, ‘Finished’, and ‘New’.

After changing color or adding emblem, the folder will also have a ‘Default‘ option in that menu, to restore to default.
