Is it possible to install Flatpaks on 21.04?

Keep getting a PPA installation error. Sorry I'm new to Linux.

What ppa? What program? What version of Ubuntu Mate are you running? If you don't give some particulars, no one can help you. Try to define your problem in as much detail as you can and then someone may be able to help you. Good Luck.

In the title I said Mate 21.04. Just looking to install Flatpacks on this edition. New to Linux. Sorry if not enough info.

You are saying about some PPA and do not provide its name or link. Please be more specific with this. I guess, that you are talking about which is mentioned in the official flatpak setup guide for Ubuntu, then it is not needed for modern Ubuntu MATE systems. So you have to remove it from the system by using command below:

sudo add-apt-repository -r ppa:alexlarsson/flatpak
sudo apt-get update

And then use Flatpak from official repositories as simple as:

sudo apt-add-repository universe
sudo apt-get update
sudo apt-get install flatpak

sudo flatpak remote-add --if-not-exists flathub

and then discover needed Flatpaks on Flathub—An app store and build service for Linux .


Didn't seem to work. Says I don't have permission to install flatpacks. :dizzy_face:

did you try:
sudo apt install flatpak
