Ubuntu 25.04

I installed Ubuntu 25.04 in a VM using the latest version (20.3) of parallels desktop on a silicon Mac. Seems to work pretty good, but sharing a folder from the host do not work. Is parallels desktop supposed to support Ubuntu 25.04? If not can I expect support for Ubuntu 25.04 in the close future? Any workaround in the meantime to make folder sharing work? I assume parallels tools is the component that do not support Ubuntu 25.04.

thanks in advance!
 
I'm facing the same issue and would like to receive a notification when it's resolved.
My configuration
macOS 15.4.1 on Apple M1 Max 64 GB memory MacBook Pro
Parallels Desktop 20 for Mac pro Edition version 20.2.2 (55879)
 
Hello @GlennGS , @tusharjoshi
Hi,
Thank you for reporting the issue with shared folders appearing empty after installing Parallels Tools on Linux.
Our development team is actively working on a permanent fix.
In the meantime, please use one from the following workaround:
  1. Edit AppArmor profile:
    a. Open Terminal on your Linux virtual machine and run the below command:
    sudo nano /etc/apparmor.d/local/fusermount3

    b. Add the following lines and save the configuration:
    mount fstype=@{fuse_types} options=(nosuid,nodev,rw,noatime) -> /media/{,/},
    mount fstype=@{fuse_types} options=(nosuid,nodev,ro,noatime) -> /media/{,/},

  2. Alternatively, you may disable AppArmor entirely by running the below on the Linux Terminal :

    a. Install AppArmor utilities if not present:
    sudo apt update sudo apt install -y apparmor-utils

    b. Set fusermount3 profile to complain mode
    sudo aa-complain fusermount3

    c. Optional: verify the profile is now in complain mode:
    sudo aa-status | grep fusermount3

    Note: Please ensure to make a back up of the virtual machine before making any changes.
Thank you.
 
Here is the `fusermount3` file I created:
```
$ sudo cat /etc/apparmor.d/local/fusermount3
mount fstype=@{fuse_types} options=(nosuid,nodev,rw,noatime) -> /media/{,/},
mount fstype=@{fuse_types} options=(nosuid,nodev,ro,noatime) -> /media/{,/},
```
However, the error is still there (I'm still unable to access the shared folder):

Running these commands helped:
```
$ sudo apt update
$ sudo apt install -y apparmor-utils
$ sudo aa-complain fusermount3
```
Thanks!
 
Thank you, option 2 works by disabling apparmor which is not the preferred solution for me. Option 1 do not work as also MetinK2 pointed out.
 
Doing this doesn't work:
Edit AppArmor profile:
a. Open Terminal on your Linux virtual machine and run the below command:
sudo nano /etc/apparmor.d/local/fusermount3

b. Add the following lines and save the configuration:
mount fstype=@{fuse_types} options=(nosuid,nodev,rw,noatime) -> /media/{,/},
mount fstype=@{fuse_types} options=(nosuid,nodev,ro,noatime) -> /media/{,/},

When i use
mount fstype=@{fuse_types} options=(nosuid,nodev,rw,noatime) -> /media/**,
mount fstype=@{fuse_types} options=(nosuid,nodev,ro,noatime) -> /media/**,
instead, everything works fine!

Yes, I figured using the syntax from /etc/apparmor.d/fusermount3 and just add the option noatime worked fine.
 
Option 1 didn't work for me but option 2 did.
Code: 
sudo apt update
sudo apt install -y apparmor-utils
sudo aa-complain fusermount3
sudo aa-status | grep fusermount3
sudo reboot
