AppImages are a way to run Linux programs from a downloaded file. They can be
convenient, but remembering where each file is, making it runnable, and
finding it again in your app menu can confuse new users.
Gear Lever is a free, open-source app that helps organize
AppImages and add them to your desktop launcher.
This beginner’s guide reviews Gear Lever, explains AppImage basics in plain
language, and shows both the easy graphical steps and an optional manual
shortcut method. Information checked against the project documentation and
Flathub on October 9, 2026.
Quick review: is Gear Lever worth trying?
Our take: Gear Lever is a useful choice if you want
downloaded AppImages to appear in your regular application menu. It can
organize them and manage updates for files with supported update information.
For one app you rarely use, you may not need Gear Lever at all.
-
Good for: beginners who want a graphical way to keep
several AppImages together and launch them from the app menu. -
Helpful features: app-menu entries, icons, file
organization, and update support for compatible AppImages. -
Limit: update support depends on the AppImage publisher.
Gear Lever cannot automatically update every AppImage. -
Not a replacement for: your Linux distribution’s package
manager. It manages AppImage files only.
The project describes Gear Lever as a central manager for AppImages. Flathub
lists integration, organization, and supported update features. See the
Gear Lever overview
and the
Gear Lever Flathub page.
AppImage, executable, and app menu: what do those mean?
An AppImage is a downloaded Linux application file. You can
run it without installing it through APT, DNF, or another system package
manager.
Making it executable gives Linux permission to run that file
as a program. It does not install the app or add it to the app menu.
Adding it to the app menu creates a launcher—an entry with a
name and usually an icon—so you can search for and open the app like other
programs. Gear Lever can help create this entry for you.
Install Gear Lever
Gear Lever is available from
Flathub. Flatpak is a way to install desktop apps on many Linux distributions;
Flathub is a catalog where those apps are published.
Graphical way (recommended for new users)
-
Open your distribution’s software app, such as GNOME Software or KDE
Discover. -
Search for Gear Lever. If your software app shows the
source, choose the Flathub listing. - Select Install and wait for it to finish.
- Open your app menu, search for Gear Lever, and launch it.
If you cannot find Gear Lever in the software app, Flatpak or Flathub may not
be set up yet. Follow the official
Flatpak setup guide for your distribution, then try again.
Optional terminal way
If you already have Flatpak and Flathub set up, you can install Gear Lever
with this command:
flatpak install flathub it.mijorus.gearleverTo start it from a terminal:
flatpak run it.mijorus.gearlever
For more commands, see the
Flatpak user guide. You can skip this section if you prefer using your software app.
Add an AppImage to the app menu with Gear Lever
-
Download the AppImage from the software maker’s official website or official
project release page. Save it somewhere you can find, such as
Downloads. - Open Gear Lever.
-
Drag the AppImage file from your file manager into the Gear Lever window. If
your version shows an Add or Open button, you can use that instead. -
Read the integration prompt. Choose the option to integrate the app if you
want it in the application menu. -
Open the app menu and search for the program’s name. It should appear as a
normal launcher.
Integration adds a menu entry and icon. Gear Lever may organize the AppImage
in its own location, so do not move or rename an integrated file manually
unless you also update its Gear Lever entry.
Mark an AppImage executable and run it without Gear Lever
This is the simple method if you only want to try an AppImage. It lets you run
the app, but it may not add a menu entry.
Using the file manager
-
Open your file manager and find the downloaded
.AppImagefile. - Right-click the file and choose Properties.
-
Open the Permissions tab. Turn on
Allow executing file as a program (GNOME Files, Nemo, or
Caja), Is executable (Dolphin), or the similar execute
permission in your file manager. - Close Properties and double-click the AppImage to run it.
The labels differ between Linux desktops. The official
AppImage quickstart
shows the file-manager and terminal methods.
Optional terminal method
Open a terminal in the folder containing the file, then replace
Example.AppImage below with its actual name:
cd ~/Downloads
chmod +x ./Example.AppImage
./Example.AppImage
chmod +x means “allow this file to run as a program.” If terminal
commands are new to you, use the file-manager steps above instead.
Create a menu shortcut manually (advanced)
You can create a launcher without Gear Lever, but this takes more care. Linux
application menus use small files called .desktop entries. The
entry needs the correct full path to the AppImage; if you move the AppImage
later, the shortcut may stop working. Gear Lever is easier for most beginners.
-
First, put the AppImage in a permanent folder, for example
/home/YOUR-NAME/Applications/. Replace
YOUR-NAMEwith your Linux username. - Make sure the AppImage is executable using the file-manager steps above.
-
Open a plain-text editor and create a file with this example, changing the
name and paths to match your app:
[Desktop Entry]
Type=Application
Name=Example App
Exec=/home/YOUR-NAME/Applications/Example.AppImage
Icon=application-x-executable
Terminal=false-
Save the file as
Example-App.desktopin your personal
applications folder:
/home/YOUR-NAME/.local/share/applications/. If that folder is
not there, create it first. -
Open the app menu and search for Example App. Some desktops
may ask you to trust or allow the new launcher the first time you open it.
A .desktop entry is the standard Linux launcher format for an
app’s name, icon, and command. See the
FreeDesktop Desktop Entry Specification. For a new user, we recommend using Gear Lever for this job instead of
editing launcher files by hand.
Alternatives to Gear Lever
-
Run the AppImage directly: mark it executable and
double-click it. Easiest if you only use one or two apps; you may need to
find the file again each time. -
AppImageLauncher: another integration tool. Its project
says it can offer a choice to run an AppImage once or integrate it into the
app menu. Check its
current releases and distribution support
before installing; the releases page includes beta builds. -
appimaged: an optional background service that watches
selected folders and integrates AppImages it finds. It can be more
automatic, but involves setting up a service. See the official
AppImage integration overview. -
Manual
.desktopentry: gives you direct
control of the launcher, but requires editing a text file and keeping its
paths correct. Follow the advanced section above.
Updates and troubleshooting
Gear Lever can manage updates when an AppImage includes supported update
information or when you set an update source. Some AppImages do not provide
this. If no update appears, check the software maker’s official release page.
The AppImage format itself does not guarantee that an app will update
automatically.
If an AppImage does not open, confirm it came from a source you trust and that
it is marked executable. Some AppImages may also need system support that is
not installed on your distribution. Check the publisher’s instructions or the
official
AppImage troubleshooting guide
before trying fixes from random download sites.
Verdict
Gear Lever is a good starting point if you want AppImages to behave more like
apps already installed on your Linux desktop. It can make menu integration and
organization easier, while the file-manager method is enough to try an
occasional AppImage. For beginners, we recommend starting with Gear Lever’s
graphical workflow and treating manual launcher files and terminal commands as
optional.

Troubleshooting: when an AppImage will not open
AppImages are designed to be portable, but they still rely on a few things from your Linux system. The exact requirements depend on how the app was built and on your distribution. Start with these checks before installing extra software.
Before you start
- Download the AppImage from the app publisher’s official website or another source you trust, and make sure the download completed.
- Choose a build for your computer’s architecture. Most PCs use x86_64 (also called amd64); some newer devices use ARM64 (also called aarch64). Check the publisher’s download notes if you are unsure.
- Keep the AppImage on a Linux filesystem where programs can run. If it is on a USB drive or mounted partition and will not launch, copy it to a folder in your home directory, such as
~/Applications, then try again.
“Permission denied” or nothing happens
The file may not be marked as executable. In your file manager, right-click the AppImage, open Properties, then enable Allow executing file as a program (the wording varies by desktop). You can also use a terminal, replacing the example name with your actual file name:
chmod +x ~/Downloads/YourApp.AppImage
Then double-click the file again. Making a file executable lets Linux run it; it does not install the app or add it to your application menu.
“AppImages require FUSE to run”
Some AppImages use FUSE 2 support to mount their contents while they run. On Debian- and Ubuntu-based systems, install the package that matches your release using your distribution’s software manager or terminal:
- Ubuntu 24.04 or newer, or Debian 13 or newer:
sudo apt install libfuse2t64 - Older Debian or Ubuntu releases:
sudo apt install libfuse2
Package names and FUSE setup differ on other distributions. Follow your distribution’s instructions and check the AppImage publisher’s notes. Do not install both packages automatically. If you cannot install FUSE, some type 2 AppImages support the workaround ./YourApp.AppImage --appimage-extract-and-run from the folder containing the file; this extracts the app temporarily and may use extra disk space.
“error while loading shared libraries” or “GLIBC_x.xx not found”
This usually means the AppImage needs a system library that is missing, or it was built for a newer Linux system or a different distribution than yours. Check the app’s official release notes for a build that supports your distribution and system architecture. Avoid downloading individual .so files from random websites or copying system libraries by hand, because that can make other programs unreliable.
The app opens but has graphics, audio, or desktop-integration problems
An AppImage may still use parts of your system, such as graphics drivers, audio services, or desktop features. Check the app publisher’s Linux requirements and your distribution’s official driver or package documentation. Gear Lever can organize AppImages and create launchers, but it cannot add missing system libraries or fix an incompatible app build.
Still stuck? Note the exact error message, your Linux distribution and version, and the AppImage’s name. Check the official AppImage troubleshooting guide and the app publisher’s support instructions before trying other fixes.
