Nice, thanks nomike and Liliana for working on this! While you=E2=80=99re at it, could you propose the relevant AppArmor profile= for inclusion in Guix proper? It would be ideal if =E2=80=98etc/guix-install.s= h=E2=80=99 would install it automatically on systems where AppArmor is enabled, similar to how it handles SELinux. Thanks, Ludo=E2=80=99.

For those who want to use the unprivileged guix daemon, one should also
include */bin/guix-daemon.

Hello to all,
I have got some news on the subject. Recently, I found this gist:
https://gist.github.com/laanwj/cddb2ec7d18e71066d21e5ee993fe971
It proposes an AppArmor profile for Guix together with some explanations.
After adapting the path to the `guix` executable like so
```
abi <abi/4.0>,
include <tunables/global>
profile guix /gnu/store/{*-guix-command,*/bin/guix} flags=(unconfined) {
userns,
# Site-specific additions and overrides. See local/README for details.
include if exists <local/guix>
}
```
and loading the profile into AppArmor, I am able to run `guix shell -C bash --
bash`. Possibly too permissive, the profile works though. It may at least
provide a temporary solution for those, like me, for who the container
functionality is critical on daily basis.
Best regards,
Marek

I've used the install.sh to install guix on my system (Ubuntu 24.10) and
I'm facing the same issue.
My guix-home config lives in ~/guix-home, so I cd to that directory in a
gnome-terminal and this happens:
```plaintext
$ guix home -L "${PWD}" container home-config.scm
guix home: error: mount: mount "none" on "/tmp/guix-directory.t82DOq":
Permission
```
I first stumbled upon the [upstream bug on
launchpad.net](https://bugs.launchpad.net/ubuntu/+source/guix/+bug/2064115)
and tried the proposed solutions there, but they did not work.
So after some more googling I found this ticket here. I added the
proposed file to `/etc/apparmor.d/guix` and rebooted my machine.
Now this happens:
```plaintext
$ guix home -L "${PWD}" container home-config.scm
guix home: error: failed to load 'home-config.scm': Permission denied
```
So it seems like we're still missing something.
I'm new to guix and I have no clue about apparmor, so I'm a bit at a loss.
cheers

Do you see any relevant information in the AppArmor logs?
I'm not familiar with AppArmor, but in SELinux there's the concept of
type transitions. "guix time-machine" builds a directory and then
executes "bin/guix" from that store location. In SELinux you would need
to explicitly allow for that transition, so that
$HOME/.config/current/bin/guix can preserve its type when executing the
independent /gnu/store/.../bin/guix.
(Looking at our SELinux policy it seems to me that we're missing a type
transition for this case, so I would assume that "guix time-machine"
also doesn't work on a system where SELinux is enforcing policies.)

Hello!
Thank you for taking time with this issue.
After loading the AppArmor profile from your message, I am able to execute “guix
shell -C hello”.
However, when trying to combine the "shell" command with the "time-machine"
command, like so:
"guix time-machine --channels=.guix/channels.scm -- shell -C hello"
I get an access denied error on the ".guix/channels.scm" file which I own and
have access to.
I tried to play around with the AppArmor profile, but with no success. Are we
still missing something?
Best,
Marek

Hello!
I believe the attached AppArmor profile should work. You need to:
1. Drop it in /etc/apparmor.d/guix (it=E2=80=99s actually not specific to
=E2=80=98guix shell -C=E2=80=99 since it matches any =E2=80=98guix=E2=
=80=99 command!).
2. Run =E2=80=9Capparmor_parser -rv /etc/apparmor.d/guix=E2=80=9D.
And then you can check =E2=80=9Cguix build whatever=E2=80=9D and =E2=80=9Cg=
uix shell -C hello=E2=80=9D.
Note that AppArmor is stateful: it memorizes previous rules (=E2=80=9Cprofi=
les=E2=80=9D)
and it=E2=80=99s not entirely clear how to remove them, especially when the=
re=E2=80=99s
no profile name.
So perhaps you=E2=80=99ll want to reboot if in doubt.
Anyway, I tested it in an Ubuntu 24.04 VM and everything seemed to work
well.
If you can confirm, we can add it to the repo and have =E2=80=98guix-instal=
l.sh=E2=80=99
install it.

No! I guess Ricardo was on the right track but this probably needs more
testing and polishing.
Is there additional info you can get by running =E2=80=9Cdmesg=E2=80=9D or =
something
like that?
Thanks,

"guix shell -C hello" and "guix > shell -CN hello" worked fine. This issue is informally reported quite frequently these days. Can someone on Ubuntu having this problem confirm that it works for them?

I then loaded the profile with "sudo apparmor_parser -qr
/etc/apparmor.d/guix-shell-container". "guix shell -C hello" and "guix
shell -CN hello" worked fine.
To refine this policy I used the following process:
1. run "sudo aa-genprof guix" in one terminal
2. run "guix shell -CN hello" in another
3. update /etc/apparmor.d/guix-shell-container as needed (often
replacing temporary directory names with glob patterns)
4. repeat
We may want to create a template file in which we replace all instances
of /gnu/store and /var/guix with their respective configured values and
install the file in the same manner as we do etc/guix-daemon.cil.
I wonder if we need to provide something similar for SELinux where we
only have the guix-daemon policy.
