Unable to install on Ubuntu18.04

I am trying to install Joplin 1.0.195 on my Ubuntu18.04 machine (Linux JetsonNano 4.9.140-tegra #1 SMP PREEMPT Mon Dec 9 22:47:42 PST 2019 aarch64 aarch64 aarch64 GNU/Linux) but cannot find a way to get it work.
The install-script runs, but does not install any desktop icon or launch / install the application.
When trying to execute the AppImage (after chmod +x) I get
bash: ./Joplin.AppImage: cannot execute binary file: Exec format error
When executing with sudo I get:
./Joplin.AppImage: 1: ./Joplin.AppImage: �: not found
./Joplin.AppImage: 2: ./Joplin.AppImage: }�P7pysH��_f��h: not found
./Joplin.AppImage: 1: ./Joplin.AppImage: �b��@@: not found
./Joplin.AppImage: 1: ./Joplin.AppImage: ELFAI: not found
./Joplin.AppImage: 19: ./Joplin.AppImage: Syntax error: Unterminated quoted string

“sudo ./Joplin.AppImage --appimage-extract” gives the same result

I re-downloaded the Appimage with wget, the result it the same
The issue might be related to the ARM64-architecture.

Any idea?
I am trying to build and install the deskop app, hopefully it’s working


The Joplin appimage is not built for the arm architecture, please search the forums and you should be able to find instances of other people having this issue. It seems that you will be able to get it to run but have to build some things yourself. Good luck.
