libnss3.so: cannot open shared object file

[maxiauer]

1. Created a fresh Linux Developer environment on ChromeOS 90.0.4430.100. ChromeOS uses Debian Buster

2. Download and Installed Adruino IDE 1.8.13 - Works OK, no issue

3. Download Adruino IDE 2.0 Beta 5 - According to the Install doc, I should run ./arduino-ide and it should work... but it doesn't

max@penguin:~/Programs/arduino-ide_2.0.0-beta.5_Linux_64bit$ ./arduino-ide
./arduino-ide: error while loading shared libraries: libnss3.so: cannot open shared object file: No such file or directory
max@penguin:~/Programs/arduino-ide_2.0.0-beta.5_Linux_64bit$ sudo ./arduino-ide
./arduino-ide: error while loading shared libraries: libnss3.so: cannot open shared object file: No such file or directory

Seems some file is missing, but I'd believe that the idea is the downloaded file would contain all files/libraries required, like it does for IDE 1.8, without needing to install extra stuff. Or if something extra is needed, the documentation would indicate that.

Thanks !!!

1. environment on ChromeOS 90.0.4430.100

3. it should work... but it doesn't

I'm afraid, it won't work: electron/electron#12712

[kittaakos]

Here is the upstream Theia issue: eclipse-theia/theia#4725

[maxiauer]

Mmm...not sure if I understand those 2 threads

In particular

1. They talk about (native) ChromeOS, which I understand why it can not support this. But Crostini (which is NOT mentioned on those links) is a VM/Container running Debian on top of ChromeOS, so not really ChromeOS

2. Somebody in those links claimed to have solved the issue using Crouton. Crouton was a "dirty way" to get Linux on Chromebooks. Crostini is a fully supported Devian Enviroment (so it works even better)... if it worked with Crouton, should work with Crostini

3. Links are from 2018 and 2019...So even if people was thinking on Crostini, but not mentioning it, at that time Crostini was in early development (and Debian 9 based). Today is much more stable, even with USB access.

Do we know what is the root cause of the issue? I can get some experts on Crostini (Linux on ChromeOS) to help, but I need to point them to the underlying issue

Thanks !!!

Does it help if you install libnss3-dev manually? (ref: symfony/panther#7 (comment))

[maxiauer]

Thanks

So, it helped... After manually installing the files:

The following NEW packages will be installed:
  libnspr4 libnspr4-dev libnss3 libnss3-dev

Now the app starts and I get a GUI with the same project I was working with last time I used 1.8.13

I do not have the time to fully test this until the weekend (create something, compile and upload), but the logs shown on the console are not that great... not sure if I shall worry about the following 2 errors (or report them on a new issue)

Thanks

[kittaakos]

Thank you for trying it.

not sure if I shall worry about the following 2 errors

You can expect some issues when you try to override the default keybindings in the IDE.

Could you please share your system information with us? This is something that I get for uname -a on my personal macOS:

uname -a  

Darwin prprpr.local 20.4.0 Darwin Kernel Version 20.4.0: Thu Apr 22 21:46:47 PDT 2021; root:xnu-7195.xxx.x~1/RELEASE_X86_64 x86_64

It would be great to know what else is missing for your environment. Is it a ChromeOS-only issue? Why is the dependency missing, and check if we could add them somehow at build time? Maybe we have to support a different app format for ChromeOS. Worst case, we have to collect a list of libs that has to be manually installed on ChromeOS by the user?

I would propose the followings if you're eager to help to track this down:

• Please get back to us with uname -a,
• (The Arduino IDE is based on Theia.) Could you please check if you have any issues running the vanilla Theia electron app? Here is the download link.
• You can check this script, we used to use it to verify if we can build and run the new Arduino IDE on a fresh Ubuntu installation. The script contains all required libs.
• Theia has strict build-time lib dependencies for the native-keymap support on Linux (see here), the question is why is it required on your environment at runtime.

[kittaakos]

OK, I did not know this: many Chromebooks come with an ARM chip. VS Code had the same issue till last year. Related: #107

not sure if I shall worry

If your Chromebook has an ARM chip, I would expect some issues with the language features too.

[maxiauer]

Back again, with the requested info:

Please get back to us with uname -a

max@penguin:~$ cat /etc/*-release

Linux penguin 5.4.99-12983-g8b7876ab9f5e #1 SMP PREEMPT Sun Feb 21 11:49:12 PST 2021 x86_64 GNU/Linux

By the way the platform is Intel Core i7 (most of Chromebooks running Linux VM/Container are, although I think they have launched the feature also in a few ARM based ones)

---

check if you have any issues running the vanilla Theia electron app?

Runs OK on the system (remember I installed libnss3-dev). I saw a few errors and warnings, mainly the same ones I saw on the console of the Arduino IDE. Will put them in another issue to avoid mixing problems here. The Keyboard issue seems related that Chromebooks have different special keys (as an example, they lack the WIN key)

---

You can check this script, we used to use it to verify if we can build and run the new Arduino IDE on a fresh Ubuntu installation

I deleted the Crostini Container (the Debian VM) and asked ChromeOs to create a new one to start from scratch before running your script. I did the usual update/upgrade and just in case checked that nothing changed on the kernel (run uname again). I had to change the repository of your script at it seems https://github.com/bcmi-labs/arduino-editor.git does not exist anymore (I used https://github.com/arduino/arduino-ide.git)

Done in 0.36s.

I checked all output looking for other errors about missing libnss3.so, but couldn't find any... The script "runs" but it seems it simply assumes that the libnss3.so will be there... (either as part of one of the modules loaded or as part of the OS)

INTERESTINGLY I tried to run the Theia GUI again and...

max@penguin:~$ ./TheiaBlueprint.AppImage 
/tmp/.mount_TheiaBm5zT5r/theia-blueprint: error while loading shared libraries: libnss3.so: cannot open shared object file: No such file or directory

A Google search shows several apps where ChromeOS Linux users are complaining about missing libnss3.so

Everything solved again after manually sudo apt install libnss3 Theia GUI and your script works OK

No sure what is the package that contains libnss3.so that "everybody seems to have installed on their systems"... In any case it would be a good idea to check for it and alert the user (or proactively include it on the package just in case)

[kittaakos]

I opened a generic issue here: eclipse-theia/theia-ide#100
Hopefully, the Theia community has an idea on how to solve this issue at build time.

after manually sudo apt install libnss3 Theia GUI and your script works OK

I am glad you found a workaround.
