Kleopatra selftest gpg connectivity error, part 2

Dear Trisquel users,

In addition to this [1] thread, which is locked:

- I have the same problem
- Doing what was said there, here are my results:

$ gpg-agent --daemon
gpg-agent[29926]: enabled debug flags: assuan
can't connect to `/home/username/.gnupg/log-socket': File or folder does not exist
GPG_AGENT_INFO=/tmp/gpg-VdLx8g/S.gpg-agent:29927:1; export GPG_AGENT_INFO;

Am I the only one, what can I do? Thank you.
