Important Notes

⚠️ Ubiquity Cursor Issue in Live Session

When using the Try FunOS (live session) and launching the Ubiquity installer, you may notice that the mouse cursor does not visually change to indicate progress (e.g., spinning or hourglass icon) during certain stages of installation. This is a known issue caused by how Ubiquity interacts with lightweight window managers like JWM.

✅ Recommended Solution:

For a smoother installation experience, we recommend selecting “Install FunOS” directly from the boot menu, instead of launching the installer from the live desktop.

I tried to install Thunderbird on a fresh install (version LTS 24.3). I did “sudo apt update && sudo apt upgrade”, then “sudo apt install thunderbird”. Can I change repository?
I received the following output:

Reading package lists… Done
Building dependency tree… Done
Reading state information… Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
thunderbird : PreDepends: snapd but it is not installable
E: Unable to correct problems, you have held broken packages.

  Hi Massimo,
  
  Sorry for the delay in replying to your comment.
  
  The issue you encountered happens because, in recent Ubuntu-based systems, Thunderbird from the official repositories is provided as a Snap package. FunOS does not include Snap (snapd) by default, so installing Thunderbird directly with sudo apt install thunderbird will result in the dependency error you saw.
  
  You don’t need to change repositories. Instead, please follow this guide, which explains the correct way to install Thunderbird on FunOS without Snap:

  The article covers the recommended installation method and avoids the snapd dependency issue entirely.
  
  Thanks for trying FunOS and for taking the time to report this 👍
