Invalid checksum preventing installation of Flatpaks from COSMIC repository

[r6915ee]

Adding a remote pointing to the current .flatpakrepo and then attempting to install any Flatpaks within this repository will throw an error and then stop the operation.

Attempting to install any of the Flatpaks from the repository in the COSMIC Store application result in an error about a version of the Freedesktop runtime, which is there even when the specified runtime is installed (the Flatpak in the screenshot being cosmic-utils/clipboard-manager):

Attempting to install a Flatpak from the command line results in a different error, completely ignoring the Freedesktop runtime. Below are examples of the error across three Flatpaks from the repository.

The last part of the error suggests an incorrect checksum:

Writing content object: Corrupted file object; checksum expected='cc700d46f407c6c5ab2d5dde474366a928b7398277e61162e7f8ec06f469f07e' actual='194420d44c511b99b60c2dec54f7f9d14a5bfbeb343da0f7619982209cea443c'

This appears to be a distribution-agnostic issue, as the above issues mentioned are on Arch and NixOS respectively. The commands above were run on my desktop Fedora machine, which only had the repository remote added today, and the COSMIC installation from yesterday (not through Fedora's official spin, however, this is from a month-old installation based on the KDE edition. COSMIC was installed from the DNF environment).

I have very recently encountered this on a new install. It seems it happens only when you just have the system flathub remote and not the user one added, so it fails identifying the dependencies.

Not an issue in Pop as a user remote is setup by default, but I've seen this happen in Cachy.

[r6915ee]

Adding the Flathub repository to the user installation manually and then adding the Freedesktop runtime version mentioned seemed to fix this problem, and now the Flatpaks install as expected. However, it's still somewhat strange that this happens in the first place when no user installation is present.

I'm guessing it's an artifact from the fact that COSMIC was originally intended for Pop!_OS back in its GNOME days, but this is still strange behavior (at least from my understanding).

For now I'll close this, just to be safe, but it's still somewhat weird.

[cappsyco]

I would say keeping this open would be a good idea as the system remote should also work, unless I'm missing some technical reason why it can't. I don't know nearly enough but it seems somewhere in the installation process from the repo, it's only looking in the user remote and not falling back to system if needed?

[r6915ee]

Alright, I'll reopen the issue.

Something of note is that the website used to host the .flatpakrepo does mention that the file was recently updated (only a couple of days ago the last time I checked), so that might have something to do with it, but I'm not sure due to my lack of knowledge on Flatpak development.

From my understanding, at the moment, you need to have the Flathub remote added as a user installation.

I've only today reinstalled Fedora to use the pure COSMIC spin - actually, only roughly an hour ago, as I write this. However, I have already added the necessary Flathub remotes and a remote pointing to this repository.

Use flatpak remotes to identify what remotes you have on your system; if the Flathub remote with the "user" option is not available, then add the remote, but explicitly define the --user flag for the subcommand so it will add Flathub to the user installation. It is, from my knowledge, safe to have both of these remotes installed. As an example, here is the list of my current Flatpak remotes (Fedora provides a unique repository, but I removed it intentionally):

$ flatpak remotes
Name    Options
flathub system
cosmic  user
flathub user

For whatever reason, I can safely install the same Flatpak without needing to install the runtime directly into the user installation, at least I didn't install it manually. There is the chance of it being different for you, however. So, when installing the runtime, make sure to explicitly define the --user flag here as well. Afterwards, you should be able to install Flatpaks from this repository.

At least, that's the workaround I know of at the moment.

[cappsyco]

Interesting, I wonder if there's a difference in priority and it's only failing when trying to use the system remote first?

[rayzorben]

Thanks, I removed system, added the platform flatpak to user context, and now it installs!

That's interesting, I have the same exact layout of the remotes. I guess Fedora just preinstalls the necessary version of the Freedesktop runtime for whatever reason?

[ExistingPerson08]

Same issue on Fedora cosmic atomic (with latest cosmic desktop from copr), even if system remote is disabled and user enabled

[ExistingPerson08]

It looks like it works now but only with user flathub remote
