Good Morning,
I'm hoping for the easy way out...after struggling for several days.

Ubunutu 260.04 LTS, tried to access the serial port, and was successful, however the systems tends to reset
the permissions after restart/power cycle. This is specifically for the Arduino IDE for Linux (at this time).

Aside from the instructions on the Arduino install page, these are the methods I've tried:
1.
sudo usermod -a -G dialout $USER
[You must log out and back in (or reboot) for this to take effect.] < did that.

2.
mkdir -p ~/.local/bin
Move your AppImage there and make it executable.


Also, when trying to enable permissions for the Arduino IDE, the App Icon disappears from the App List Page
after performing the following commands:

sudo apt update
sudo apt install libfuse2

Make the File Executable; navigate to the directory where you downloaded the file (e.g., cd ~/Downloads).
chmod +x arduino-ide_2.x.x_Linux_64bit.AppImage


I've searched here, Google, and YouTube, but can't seem to figure this out.
Thank you for your time!

ETA:

Found that adding --no-sandbox, after the filename, executes the IDE from the Terminal.

Also performed:

sudo sysctl -w kernel.apparmor_restrict_unprivileged_userns=0

Now it runs from the Desktop, when double-clicking the install file (from Downloads).

The icon still does not appear on the App page.
