A really weird Libreoffice issue that’s related to GnuPG. It’s F39, an nspawn container…when I click “Options” in Libreoffice it freezes, ‘gpg’ process appears and Libreoffice only unfreezes when I ‘killall gpg’ from the terminal. The Options default screen does have OpenPGP key related settings that default to ‘no key’ so it’s probably related but I didn’t have this issue before on F37.
Workaround that seems to work: going to ~/.gnupg/ and edit common.conf file there and comment out use-keyboxd there. Then, of course you will lose some functionality but which may be irrelevant in a container.
