I followed the pod directions to install Arduino IDE on linux. Including the part about 32 bit compatibility.
I get a missing error:
nathan@nathan-B550:~$ sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
E: Unable to locate package libncurses5:i386
A web search suggested I use libncurses6:i386 instead. I wanted to check here first.
Just try it without libncurses. I don’t think it’s required.
If it works for you, can I can remove that from the instructions.
I did have the error.

If you run:
ldd /home/nathan/.arduino15/packages/proffieboard/hardware/stm32l4/4.6/tools/linux//dfu-suffix
What does it say?
not a dynamic executable
Did you install the other libraries? libc6:i386 and libstdc++6:i386 ?
I ran this single command:
sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386
But maybe when it failed at libncurses5, it didn’t install the rest?
That’s right, run it again, but without the libncurses part and see if it works better.
Those 2 did install, but I still have the error
Compilation error: fork/exec /home/nathan/.arduino15/packages/proffieboard/hardware/stm32l4/4.6/tools/linux//dfu-suffix: no such file or directory
ldd /home/nathan/.arduino15/packages/proffieboard/hardware/stm32l4/4.6/tools/linux//dfu-suffix
now outputs:
linux-gate.so.1 (0xea5ad000)
libpthread.so.0 => /lib/i386-linux-gnu/libpthread.so.0 (0xea592000)
libc.so.6 => /lib/i386-linux-gnu/libc.so.6 (0xea34a000)
/lib/ld-linux.so.2 (0xea5af000)
I found this issue, which sounded a lot like mine:
But it did not work. Should I submit an issue? I do not want to pester you too much.
You did this right?
sudo dpkg --add-architecture i386
If you run
home/nathan/.arduino15/packages/proffieboard/hardware/stm32l4/4.6/tools/linux//dfu-suffix
manually, does that work?
What linux are you running?
Also, how did you install arduino?
Yes.
bash: home/nathan/.arduino15/packages/proffieboard/hardware/stm32l4/4.6/tools/linux//dfu-suffix: No such file or directory
Coming from Windows, it looks like the double // before dfu-suffix would cause trouble?
Ubuntu 25.04
Arduino 2.3.6 from the gnome software
I think the double slash should be fine, but I missed a slash in the beginning, it should be:
/home/nathan/.arduino15/packages/proffieboard/hardware/stm32l4/4.6/tools/linux//dfu-suffix
If that doesn’t work, try removing the double slash and see if that works better.
I hope this didn’t install a snap or something…
snaps has weird and arbitrary limitations, that could maybe make 32-bit software not work…
If it works from command-line, but not from arduino, try the appimage from the arduino website and see if it works better.
Now I get this:

It shouldn’t. I didn’t use the Ubuntu app manager, and downloaded the gnome software myself (to avoid snaps as well). This is what my app list shows, flatpak.
I will try the app image to eliminate that variable.
Looks like it used flathub.
Flathub has a weird way to install things, but I haven’t had any problems with it so far. However, it is possible that flathub is the problem. I know it works with the appimage (because that’s what I use) but I have not tried installing Arduino from flathub.
thanks for the help, but there is more issues
When starting the appimage, it said this:
dlopen(): error loading libfuse.so.2
AppImages require FUSE to run.
You might still be able to extract the contents of this AppImage
if you run it with the --appimage-extract option.
See https://github.com/AppImage/AppImageKit/wiki/FUSE
for more information
I installed fuse with sudo apt-get -y install libfuse2
now it says this upon starting the appimage:

I’ve had this error, but I don’t have it anymore.
Don’t remember what I did to fix it though.
I recommend asking the all-knowing trash heap[1].

Well, I’ll be it worked! It successfully compiled a v2 and v3 config.
I had to use --no-sandbox to use it.
It appears to just run, but not “install”? Is that correct? Is there a way to get an entry in the app launcher and/or file association so I can run it from the proffieos.ino?
Yes, that is correct.
Almost certainly.
gnome app shortcuts are just text files, you can probably add one in .local/share/applications/
Not sure how you add a file association though. I do almost everything form a text prompt in linux, so file associations are not really a thing that I care about.
Also, arduino opens in the same state as you closed it, which usually means you can just start arduino and go from there…
