The most reliable way to install Arduino IDE on Ubuntu 24.04 (Noble Numbat) or Ubuntu 22.04 (Jammy Jellyfish) is to download the current stable Arduino IDE 2 Linux build from Arduino’s official software page. The AppImage runs without a system-wide installation. After launching it, add your user to Ubuntu’s dialout group, install the board package, select the board and port, and upload a test sketch.
Before you begin
- Ubuntu Desktop 24.04 LTS or 22.04 LTS with a graphical session.
- Internet access and permission to use
sudo. - An Arduino board and a USB data cable. A charge-only cable will power a board but cannot upload sketches.
- Enough storage for the IDE, board cores, compiler tools and libraries.
Check your CPU architecture:
dpkg --print-architectureMost Intel and AMD PCs report amd64. ARM Ubuntu systems may need a different build or may not be supported by the Linux desktop package offered for your release; match the architecture shown on Arduino’s download page rather than assuming the amd64 file will work.
Download the official Arduino IDE 2 Linux build
Open the official Arduino IDE 2 installation guide or Arduino’s software page. Choose Arduino IDE 2, select Linux, choose the architecture matching your system, and download the current stable release. Avoid nightly builds unless you are specifically testing unreleased software. Keep the original filename; future releases will use different version numbers.
Install and launch the AppImage
In a terminal, run:
cd ~/Downloads
chmod +x arduino-ide_*.AppImage
./arduino-ide_*.AppImagechmod +x gives the downloaded file execute permission; it does not install Arduino system-wide. If the shell says the file does not exist, inspect the actual download name:

ls -lh ~/DownloadsUse Tab completion or replace the wildcard with the exact filename. Do not run the IDE with sudo.
Optional: keep the AppImage in a permanent location
mkdir -p ~/Applications
mv ~/Downloads/arduino-ide_*.AppImage ~/Applications/arduino-ide.AppImage
chmod +x ~/Applications/arduino-ide.AppImage
~/Applications/arduino-ide.AppImageThis makes the launch path stable. A desktop shortcut is optional, but its Exec= entry must point to the file’s actual location. If you move the AppImage later, update the shortcut.
Fix an AppImage FUSE error
If launch fails with an error such as dlopen(): error loading libfuse.so.2, check which compatibility package your Ubuntu repositories provide:
apt-cache policy libfuse2 libfuse2t64On a typical Ubuntu 22.04 system:
sudo apt update
sudo apt install libfuse2On a typical Ubuntu 24.04 system:
sudo apt update
sudo apt install libfuse2t64Package availability depends on enabled repositories and system updates, so install the compatible candidate shown by APT rather than treating either name as universal. As a fallback, you can extract the AppImage:
./arduino-ide_*.AppImage --appimage-extract
./squashfs-root/AppRunExtraction is less convenient to update and does not automatically integrate with desktop menus, so use it only when the normal AppImage cannot mount.

Give your user access to Arduino’s USB serial device
Ubuntu uses device permissions managed through udev. Add your current user to the usual serial-device group:
sudo usermod -aG dialout "$USER"Sign out and sign back in (or reboot) so the new supplementary group reaches your desktop session. Verify it with:
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
groupsThe output should include dialout. This fixes a normal permissions problem, but it cannot repair a bad cable, defective board, missing USB-serial support, wrong port, or a port occupied by another application. Running Arduino IDE as root can create root-owned configuration files and only hides the underlying issue.
Connect the board and find its port
Before connecting the board, list likely serial devices:
ls /dev/ttyACM* /dev/ttyUSB* 2>/dev/nullRun it again after plugging in the board. A newly appearing device is usually the one to select. Common names include:

Install the correct board package
Installing the IDE does not install every board platform. In Arduino IDE 2, open Boards Manager, search for your board family, and install its platform. For example, Uno, classic Nano and Mega boards normally use Arduino AVR Boards. Zero, MKR and other families use different platforms; ESP8266, ESP32 and RP2040 boards use vendor or third-party packages.
Libraries are separate from board packages: the board package supplies board definitions, compilers and upload tools, while libraries provide reusable sketch code. Install libraries through Library Manager when possible.

Select the board and port
- Connect and power the board.
- Use the board selector at the top of the IDE, or open Tools → Board, and choose the exact model.
- Choose the detected device under the port selector or Tools → Port.
- For a classic Nano, try the correct processor option (for example, ATmega328P or an older bootloader) if upload fails.
Menu wording can vary slightly between IDE releases, but the functions are the same: select a board definition and a serial port.
Compile and upload Blink
- Open File → Examples → 01.Basics → Blink.
- Click Verify (checkmark) to compile.
- Click Upload (right-arrow).
- Watch the output panel for a successful upload and the board’s built-in LED or documented status indicator.
Verification tests compilation only; it does not test USB access or uploading. A successful upload also does not prove that an external circuit is wired correctly. Some boards reset into a different USB mode during upload, so the port can disappear and reappear under a new name.
Common problems and fixes
| Symptom | Likely cause | What to do |
|---|---|---|
| AppImage is “not executable” | Execute bit is missing | Run chmod +x filename.AppImage. |
libfuse.so.2 error |
FUSE compatibility library missing | Use apt-cache policy, then install the package appropriate to your Ubuntu release. |
| No port appears | Charge-only cable, bad USB port, board not powered, or USB-serial issue | Try a known data cable, another USB port, and dmesg --follow. |
| Permission denied | Session does not yet have dialout |
Add the user to dialout and start a new login session. |
| Board selector is incomplete | Platform not installed | Install the matching package in Boards Manager. |
| Header file cannot be found | Required library is missing | Install it through Library Manager. |
| Upload fails but compile works | Wrong board or port, busy port, bootloader setting, or cable problem | Recheck board and port, close serial monitors, try the Nano processor option, and inspect upload output. |
| Port changes during upload | Board entered bootloader mode | Wait for reconnection and select the newly appearing port. |
Only sudo makes it work |
Incorrect user permissions or root-owned files | Fix group membership and file ownership; stop launching the IDE as root. |
Arduino IDE 2, IDE 1, CLI and Cloud
Arduino IDE 2 is the recommended starting point for a new desktop installation. IDE 1.8.x is the legacy branch and may still be needed for an old extension or compatibility-sensitive workflow. Ubuntu’s apt package may be older or may provide IDE 1, so the official Arduino download is the clearest baseline for IDE 2; do not assume sudo apt install arduino installs the current application.
Arduino CLI is a separate command-line tool for automation, headless systems and reproducible builds, not simply the GUI without its window. Its equivalent core and library commands include:
The Tool Desk
Outbyte PC Repair FREERepair Windows errors before they cause bigger problemsFix Now →Outbyte Driver Updater FREEFix the driver behind crashes, sound loss and screen glitchesFind Drivers →arduino-cli core update-index
arduino-cli core search arduino
arduino-cli core install arduino:avr
arduino-cli lib install LibraryName
arduino-cli lib install [email protected]Arduino Cloud Editor avoids a full local IDE but requires a browser-based workflow and may require additional hardware support software. It is not a full offline substitute.

Frequently Asked Questions
Can I install Arduino IDE with APT?
You can inspect Ubuntu’s repository package, but its version and packaging vary and it may be legacy IDE 1. For IDE 2, use Arduino’s official Linux download as the troubleshooting baseline.
Why does my board appear as /dev/ttyUSB0 instead of /dev/ttyACM0?
Boards using CH340, CP210x or FTDI USB-serial bridges commonly use /dev/ttyUSB*. Native-USB boards often use /dev/ttyACM*. Either can be correct.
Crashes, No Sound, or Screen Glitches?
Random freezes, missing sound and display glitches usually trace back to one bad driver. Find and replace yours safely.Free scan · under a minuteWindows Errors? Fix Them Before They Spread
