Seafile CLI sync certificate error

If you get the following error while syncing your seafile library with a server using a self signed certificate, you have to add the certficate to your certificate store.


urllib2.URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:581)>


  1. Retrieve the self-signed certificate (usually .pem or .crt)
  2. Make sure you have ca-certificates installed
    apt-get install ca-certificates
  3. Copy your certificate into the certificate folder
    cp cert.pem /usr/share/ca-certificates
  4. Activate the certificate
    dpkg-reconfigure ca-certificates
