I recently moved from the RPM KeePassXC version to the Flatpak one, because integration with the Browser no longer worked. Simply my RPM version was old.

As a flatpak enthusiast, I installed the Flatpak version. But, it was not without a problem.

The easy way is to just create the link to the flatpak binary.
# sudo ln -s /var/lib/flatpak/app/org.keepassxc.KeePassXC/current/active/files/bin/keepassxc-proxy /usr/bin/keepassxc-proxy
After that, the plugin was able to connect and it worked as with RPM version.

The copy from and to the database from/to clipboard doesn’t work either.
The workaround mentioned  fixes that problem.
Mainly I wanted to share the workaround somewhere, and I think it could be good article.
Nevertheless, also  fixes the issue with the window decoration, it was mentioned in  as well.
