Package: boinc
Version: 6.4.5-1
Severity: important


Trying to connect to the World Community Grid project I am getting the message
"Scheduler request failed: Peer certificate cannot be authenticated with
known CA certificates"

My ca-certificates package version is 20081127 and even reinstalling it didn't
However, downloading
and saving it as /var/lib/boinc-client/ca-bundle.crt did work
(/var/lib/boinc-client/ca-bundle.crt originally is a symlink to

http://boinc.berkeley.edu/trac/wiki/Error/Scheduler%20request%20failed says
that this error can be caused by incorrect date or a proxy, but this is not the
case with this machine (and I can reproduce it; using the ca-bundle.crt as
symlink to /etc/ssl/certs/ca-certificates.crt, it fails. Using ca-bundle.crt
downloaded from their site, it works).

Is there something else that I can do, please?

Thank you!

Best regards,
