try execute with sudo

I tried sudo /usr/bin/unityhub and got this:
[0525/211423.912756:FATAL:electron_main_delegate.cc(293)] Running as root without --no-sandbox is not supported. See https://crbug.com/638180.
So I tried sudo /usr/bin/unityhub --no-sandbox
and got this:

Unity, guys go back to the App login. I shouldn’t need to use the browser for this stuff.
I don’t even want Chrome on my Linux system… (just face-palm man)

Also its not working for me, Login is just now totally broken on Ubuntu 24.04. Great job guys… come on man. Why in gods name would you make a sign-in process that requires inner-process security violations that not only makes multi-user login a nightmare but also will just break depending on the browser used. This is the dumbest thing and I keep running into these login issues for years now since this change. Please guys… just please.

Neither for me on Ubuntu 24.04 LTS. Please can you address Unity?

I was having the same problem. It seems ubuntu 24.04 implemented some changes to how it restricts apps. Take a look at https://github.com/ungoogled-software/ungoogled-chromium/issues/2804.

This worked for me! Thank you

TL;DR:
Ubuntu 24.04 has more strict apparmor policies, denying Unity Hub actions

Fix:
Create a file in /etc/apparmor.d/unityhub
Write the following snippet to it:

abi <abi/4.0>,
include <tunables/global>
profile unityhub /opt/unityhub/unityhub-bin flags=(unconfined) {
userns,
# Site-specific additions and overrides. See local/README for details.
include if exists <local/unityhub>
}

Restart apparmor:
sudo systemctl restart apparmor.service

Hey, I’ve been seeing problems with other programs too, they are related to more strict apparmor policies in Ubuntu 24.04. I fixed this for some programs already and it’s also working for Unity Hub (so you don’t need to use the option –no-sandbox. Here’s the gist on github on how to do it:

worked for me also!.. but as i have checked here we are running the unity unconfined which means if unity or unity related components compromised system can be compromised by doing this unconfined profile for unity. if my understanding is wrong.pls correct me. else we need to search for a more secure way to let unity create sandbox

copy /opt/google/chrome/chrome-sandbox to unityhub directory
and “chmod +s chrome-sandbox”
It works fine without security problems.

[Bob_The_Building]

At: Debian -- Package Download Selection -- chromium-sandbox_128.0.6613.84-1_amd64.deb Download A new Chrome-sandbox, insert into Directory, e.g. sudo mv ~/Downloads/chrome-sandbox /opt/unityhub/
Rename it to chrome-sandbox. You need to make sure that /opt/unityhub/chrome-sandbox is owned by root and has mode 4755.

For me, This fixed it I’m using the newest ubuntu

Still works on Ubuntu 24.04… Great solution!!
