De alguna manera, hoy, de repente, mi cliente de archivos marinos arrojó este error. No creo que sea un problema de archivo marino, porque mi openssl arroja exactamente el mismo error:
user@nb-user:~$ echo |openssl s_client -connect seafile.mydomain.ch:443

Para mí, la parte de la cadena se ve exactamente como debería. El apache conf también debería estar bien:

No puedo encontrar cuál es mi problema ... (ca-certificados está instalado en mi lubuntu 14.04). Su sitio no es aplicable porque vincularon su certificado de Clase 1, pero el mío es emitido por su Clase 2.
-CApath /etc/ssl/certs/
sucede si agrega o dónde se almacenan sus certificados? ¿Quizás te estás perdiendo el certificado raíz en la cadena?
