[TriLUG] userns

[Brian McCullough via TriLUG]

Ran into something interesting over the weekend.


I had encountered a browser named Brave in Android, and thought that I
would see if it existed for Linux, and try it out.

When I found it, there was a message about possible "sandbox" issues,
and instructions on how to fix it.

I installed Brave in my Debian 9 system successfully.

Those instructions involved adding the following to sysctl:

kernel.unprivileged_userns_clone=1


I did so, and Brave is another interesting web browser.


However, I can no loger change between desktop windows! ( Ctrl-Alt-Arrow
)



I am at the point of uninstalling Brave and undoing that change to
sysctl.



Any suggestions?


Thanks,
Brian
