I updated yesterday to Fedora 42, as always the update was super smooth. The only problem I faced was that my Gnome Online Accounts stopped working. After a quick check I found the reason, the Gnome password and key manager (seahorse) has been removed during the update from Fedora 41 to 42. After reinstalling it everything works fine again.
Still, I wonder if this was a small update bug or is Gnome/Fedora in the process of replacing seahorse with something else?
I am not sure what happened, but in a default install, the graphical user interface seahorse (“Keyrings and passwords”) is not installed in Fedora. I can confirm this as I am currently on a fresh installation of Fedora 42. The underlying infrastructure remains the same, though.
If you had Seahorse installed, it should in principle be preserved on an upgrade. Perhaps a bug or issue during upgrade indeed?
