Unsupported command-line flag: --no-sandbox

@dsturbd, @childishgiant - You both installed via snap/store/some app software, is that correct?

well on manjaro, i installed it from the software center (pamac), not sure of any other way other than to use pacman -S brave, which would accomplish the same thing

sudo pacman -S brave on the terminal for me. Yeah it’s the same.

I just want to reiterate that Brave only maintains the packages listed at https://brave-browser.readthedocs.io/en/latest/installing-brave.html#linux.

This means that the .pkg.tar.xz file from which pacman installs Brave for us was built solely by the unofficial maintainer, right?

Correct me if I’m wrong: stuff like this thread and this one could be redirected to them. Right?

EDIT: @Mattches @toml
Edit 2: Please, can someone just answer my question with a yes or a no??

If you are using Arch, use this command to enable support to run unprivileged containers for the current session: sysctl kernel.unprivileged_userns_clone=1

Is it fixed in any of these versions?:

$ pacaur -Ss brave
community/brave 0.61.50-1 [installed]
Web browser that blocks ads and trackers by default (latest binary release).
community/brave-beta 0.62.25-1

Web browser that blocks ads and trackers by default (binary release).
aur/brave-dev-bin 0.64.39-1 (7, 3,41829)
Web browser that blocks ads and trackers by default (dev binary release).
aur/brave-git 0.24.1.r236.g7e6875794-1 (22, 0,035645)

aur/brave-nightly-bin 0.65.28-1 (1, 0,815486)
Web browser that blocks ads and trackers by default (nightly binary release).

Brave starts without problems when using kernel.unprivileged_userns_clone=1. Is this strictly necessary or is it fixable? I’m not too comfortable playing with kernel parameters that I don’t know anything about.

I am running Brave under Manjaro Linux (version 0.62.51, package brave-bin installed from the AUR) and I see the message about unsupported command line flag. It goes away after a

sudo sysctl kernel.unprivileged_userns_clone=1

Nonetheless, that raises some security concerns; see

https://lists.archlinux.org/pipermail/arch-general/2017-February/043066.html

Would it be possible for the Brave devs to build the browser so that users wouldn’t need to enable unprivileged user namespaces?

If the namespaces system itself is problematic, this means that even the officially-supported distros have this issue, right?

brave+wayland(native)+flatpak=yes? :grinning:
is very good way for linux all distributions :sunglasses:

So, it looks like this is not a Brave issue but rather an issue with the AUR compile?

For the Brave devs, is there a planned install for Arch?

Or, as the prior poster mentioned, an official flatpak?

Arch is on our list of repos to support directly, but we have a lot of packaging to do.

Same issue here:

Manjaro Linux 18.0.4
Brave 0.65.114-1

Installed directly from Manjaro software repos.

The above solution does not work for me.

Bit gobsmacked that this issue has persisted for over 7 months now.
