SUMMARY (This bug is filed for informational purpose, not a real bug) Kleopatra Flatpak may not work out of box. It needs an running gpg-agent from host to work, and here are some instruction for this. In order to run gpg-agent in the background, you can run following command from your terminal: ``` gpg-agent --daemon ``` You can add this line in your `~/.bashrc` or `~/.profile`, so that gpg-agent can start on your login. Or you can utilize systemd to start it. See this for more infomation: https://sources.debian.org/src/gnupg2/2.2.39-1/doc/examples/systemd-user/README/
bugs.kde.org is not the right place for documenting how to run the Kleopatra flatpak. I'll close this report. People running into this problem will still be able to find this report.
