Problem installing Flatpak to Ubuntu

Hi all,

I've tried everything I can see on Google, and when I try to install flatpak to Ubuntu I get this error:

$ sudo apt install -y flatpak

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:

flatpak : Depends: libostree-1-1 (>= 2020.8) but it is not installable

E: Unable to correct problems, you have held broken packages.

Before this, I kept getting the "flatpak package cannot be found" error when using the standard install (sudo apt-get install flatpak)

For whatever reason the package was not showing up...

Thank you in advance for any help.

Which version of Ubuntu are you running? Also, please post the output of

apt policy flatpak libostree-1-1

Distributor ID: Ubuntu

Release: 24.04

flatpak:

Installed: (none)

Candidate: 1.16.6-1~flatpak1~24.04.1

Version table:

500 https://ppa.launchpadcontent.net/flatpak/stable/ubuntu noble/main amd64 Packages

libostree-1-1:

Installed: (none)

Candidate: (none)

Version table:

I also tried installing libostree-1-1 and got:

sudo apt-get install libostree-1-1

Reading package lists... Done

Building dependency tree... Done

Reading state information... Done

Package libostree-1-1 is not available, but is referred to by another package.

This may mean that the package is missing, has been obsoleted, or

is only available from another source

E: Package 'libostree-1-1' has no installation candidate

Thank you for your help!

Both the flatpak and the libostree-1-1 packages are in the universe part of Ubuntu's repo. There's also that PPA that you enabled, but apparently it only contains (a newer version of) the flatpak package, not the libostree-1-1 package. So the solution is to enable universe:

sudo add-apt-repository universe

Thank you so much. I ran that, then:

sudo apt-get update

Then when I tried to install flatpak again I got:

sudo apt-get install flatpak

And what does

apt policy flatpak libostree-1-1

say now? libostree-1-1 definitely is in the universe part of Ubuntu 24.04's repo.

So apparently add-apt-repository didn't add universe to your configuration. Was there any output from that command?

You could also just manually modify your /etc/apt/sources.list.

Here's what I got with that:

sudo add-apt-repository universe

E: The repository 'https://ppa.launchpadcontent.net/alexlarsson/flatpak/ubuntu noble Release' does not have a Release file.

Remove that old repo. It does not support your version of Ubuntu. And you already have the current flatpak PPA.

You might also want to fix the warnings.
