Linux Mint 22 doesn't install Collabora Office

Installation & Configuration
1

Hi.

I’m using Linux Mint 22.2 with Libreoffice.

I read about Collabora Office and I’ll like to try it.

I downloaded the Linux version (collaboraoffice-v25.04.7.2_final.flatpak) but Linux Mint doesn’t recognize a program to install it.

Can you help me?

Hi - I’m certainly no expert, but I found some instructions here:

@JPSanchez can you please describe the steps you followed to install the flatpak ?

I downloaded the program from the webpage:
collaboraoffice-v25.04.7.2_final.flatpak

When I double click in the program I always receive this message:

I can’t progress from there.

Hi @JPSanchez

Here is the quick fix.

1. Enable Flatpak support (if missing)

Mint usually comes with Flatpak support, but some editions don’t. Run:

sudo apt update
sudo apt install flatpak

Then log out and back in once.

2. Install the Collabora Office .flatpak file

Now run:

flatpak install collaboraoffice-v25.04.7.2_final.flatpak

Thanks

Thank you very much.
Linux Mint doesn’t use flatpak, so I didn’t know the appropriate language to install it.

Where can I find information on opening a LibreOffice document in edit mode?
