Warning: 'sandbox' is not in the list of known options, but still passed to Electron/Chromium

Question

I am using Linux Mint 20 and vscode 1.52.1.

My ~/.xsession-errors file shows Warning: 'sandbox' is not in the list of known options, but still passed to Electron/Chromium.

What is causing this error and what is the solution to it?

Airfield

this is when you run your app, or when you run vscode (which is built on top of electron) – Septuagint

@Septuagint why is it considered a warning? – Airfield

Happens on Void linux too, except 'Warning: 'app' is not...' output direct to console: code --version gives 1.52.1, electron9 --version gives v9.3.4. – Dyke

Seen on Ubuntu 21.04 too. The warning is produced while opening a file in VSCode. – Tiltyard

I started getting this warning today. CONFIG: sh Version: 1.58.0 | Commit: 2d23c42a936db1c7b3b06f918cde29561cc47cd6 | Date: 2021-07-08T06:53:55.113Z | Electron: 12.0.13 | Chrome: 89.0.4389.128 | Node.js: 14.16.0 | V8: 8.9.255.25-electron.0 | OS: Linux x64 5.8.0-59-generic snap | – Impeditive

This is the first time I see this warning when opening vscode from terminal – Aneroid

Seen on Ubuntu 20.04 too, when opening a file in VSCode, just like @Tiltyard said. – Thoroughgoing

Its mostly with vs code version 1.58.0 June 2021 release – Rissole

There is currently a ticket on github.com for this issue. It is with the new release! – Felipafelipe

I see this warning since 1.58.0 on Ubuntu – Selemas

Answer 1

I removed the snap version and install the deb file which works for me

sudo snap remove code

Downlaod code_1.58.1-1626158276_amd64.deb (latest) file from https://code.visualstudio.com/download

and install it with --fix-broken option

cd ~/Downloads/ && sudo apt --fix-broken install ./code_1.58.1-1626158276_amd64.deb

Answer 2

I encountered this error last night. To resolve it, I reverted my Electron/Chromium app to a previous version.

snap revert code-insiders
