It looks like you are still using the 42 repo on a 43 environment.

Are you using this path?

https://download.opensuse.org/repositories/home:/Slimbook/Fedora_43/home:Slimbook.repo

Just tried today to install this repo after a clean install and update, and got this error:

sudo dnf install slimbook-meta-plasma slimbook-meta-evo
Updating and loading repositories:

Failed to resolve the transaction:

You can try to add to command line:
  --skip-broken to skip uninstallable packages

FYI: Fedora 43 goes with Python 3.14 at the time of writing this comment

Seems to work so far. Had to install slimbook-meta-executive also.

Thanks!

Good morning,

In the last few days we added a repository for Fedora 43 found here, however, even though it exists and it's supported, we still need to test it properly, so beware.

Regards,
