Error spawning child process

[cvanelteren]

When trying to flash the archiso using 2:1.19.21-3 I was faced with the error.

• Etcher version:
• Operating system and architecture:
• Image flashed:
• What do you think should have happened:
• What happened:
• Do you see any meaningful error information in the DevTools?

Hey, it seems you are using balena-etcher from AUR. If so, please rebuild it and try again.

[cvanelteren]

Hi @sukanka! I tried several versions offered through AUR without success.

• etcher-bin
• balena-etcher
• etcher-ng-bin

With the etcher-git version a different error pops up

With rebuilding it, are you referring to do this directly from release page?

No, I mean rebuild balena-etcher from the source, just clone its AUR repo and run makepkg or extra-x86_64-build in the directory.

Please also make sure you use the same version of nodejs as you build it in the chroot

[Perlovka]

Same is happening with prebuilt app (linux-x64) from the site. As far as I understand, etcher is completely unusable for now. Gazillion bugs opened and zero fixes for more than a month. RIP.

[binba2]

Getting the same exact thing, from the prebuilt (macos-x64). MacOS 12.7.2.

[cvanelteren]

I used rufus in the mean time to burn the iso. Works like a charm.

[Vyacheslav1557]

same for me

[hwac121]

Please fix this guys, my favorite and usually dependable burning app is no longer of any use at all.

Also @sukanka building from source gave me the same error.

quite strange, I have tested it locally and it works just fine.

I get the 'Error spawning child process' error as well.

I've downloaded and ran the following and they all gave me the same problem.

• balena-etcher_1.19.21_amd64.deb
• balena-etcher_1.19.19_amd64.deb
• balenaEtcher-linux-x64-1.19.21.zip

I've tried it with multiple ISO files.

Trying to download balenaEtcher-1.19.21-x64.AppImage and just running that gives a different error (Error: (0 , h.requestMetadata) is not a function) when trying to add an ISO link and .

System info:
6.1.0-23-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.99-1 (2024-07-15)

[Keeqler]

On ArchLinux, I got the same error because I didn't have an authentication agent (like polkit-kde-agent) installed and running.
Etcher needs this so it can prompt for your password.

[z0rg0n]

It looks like polkit-kde-agent is already part of Debian?
https://packages.debian.org/bullseye/polkit-kde-agent-1

Anyway if anyone is just looking for a work around I was able to get it the thumbdrive flashed using dd in Debian as showing here:

@cvanelteren did you try running it as administrator?

[cvanelteren]

@cvanelteren did you try running it as administrator?

No as it is not supported by electron.
Installing the kde-pol-agent did not resolve it.

[wpf99]

I solved it by making my account an administrator on Mac. I had been a normal user and would use the admin account for installs, etc. when prompted for the use password I put in my password and would receive this error message. I went to Users and Groups and promoted myself to administrator and the problem is solved. It seems like this error is essentially: "not in sudoers group..."

[0913/203740.556208:FATAL:electron_main_delegate.cc(295)] Running as root without --no-sandbox is not supported. See https://crbug.com/638180.

I solved it by Running as administrator.

[cvanelteren]

Yes, but it cannot find the monitor then on wayland

[bps86]

On X11, Usually the way to fix this is to run it with sudo without sandbox. The problem is that this method is impossible on wayland because it's kind of hard to make sudo work with GUI apps.

Wow, a rare win for windows.

[Perlovka]

Wow, a rare win for windows.
I would not call security flaw a win.

[thegoodduck]

Hey me too, now using GNOME Disks

[IPlayZed]

This happens as well on me on Windows 11 23H2, I do not see any Windows Defender related things.

[achodeveloper2]

Def sounds like a security flaw.

Related, just with more debug logs, screenshots, ++: #4356

I see people mentioning sudo and admin rights here. That could be related to the debug logs I see mentioning:

"Error: Elevation timeout\n 

I guess this means elevation of rights (privileges), but I am not sure.
