bug#71226: ‘guix shell -C’ doesn’t work on Ubuntu 24.04

[Marek Felšöci]

Hello to all,

I confirm the issue on my Ubuntu 24.04 installation with Guix coming from apt 
repositories.

I followed the steps from the Ricardo's reply, but the problem persists with the 
same error:

```
guix shell: chyba: mount: mount "none" on "/tmp/guix-directory.DFemEr": Prístup 
odmietnutý
```

Note that in the above message 'Prístup odmietnutý' means 'Access denied'.

Have there been any new developments regarding this issue?

PS: My current Guix generation is based on the commit c3290ce of the official 
Guix channel.

Thank you very much!

Best regards,
Marek
